 # Foundation multi-player map

Successfully complete single player mode on any difficulty setting to unlock the
Foundation multi-player map. Note: There is a glitch that prevents some people from
unlocking the map as it was originally intended. The way it has been done successfully is
as follows: Successfully complete single player mode on any difficulty setting. Create a
new profile. Begin a co-op game on the last level with the newly-created profile with the
second player. When you reach a section where you fly a Banshee, the new profile must
perform a barrel roll and a loop-the-loop. Finish the campaign and the new profile can
access the Foundation map when hosting split-screen, System Link, or Xbox Live games.
Alternately, if you have Xbox Live, go to the Microsoft Content download menu. Then,
download all recently updated content. Go to a game menu. Go to change the options, then
change the map. It should be at the very bottom.
# Infinite ammunition or power

This trick requires levels that have either Covenant or Marines following you. If you have
a powerful weapon that has very limited power (for example, the energy sword, or Covenant
sniper), or weapons that are very powerful (for example, Human sniper or rocket launcher)
give them to the A.I. following you. As they use them, the weapons will never run out of
power or ammunition. Also, they can use them very well.
# Infinite ammunition in campaign mode

To do this trick, your weapon must be reloadable and have at least one clip in it. When
your weapon has no shots remaining, before you reload, switch to your other weapon. Find
an ally that you can switch weapons with, then quickly switch to the weapon that needs to
reload and swap with the ally. If done correctly, you will see your ally reload the
weapon. Swap your weapon back to see that your clip is now full, and it did not take away
any ammunition.
# Have the same primary and secondary weapon while not dual wielding

This trick can only be applied to weapons that can be dual wielded. For this trick to
work, you need four dual wielding weapons in one place. Two or three weapons of the total
four weapons must be the same, but remember a minimum of two of same weapon is necessary
in order to have same weapon for both primary and secondary slot. For example, have two
needlers, an SMG and a plasma rifle. To get two needlers, carry one needler as your
primary weapon then select anything else but the needler (such as the SMG gun) as your
secondary weapon. Note: You cannot select the same weapon as your secondary any way. Dual
wield plasma rifle with the SMG then go to the needler that is on the ground, hold X, and
substitute the second needler with the SMG gun. Then, throw the plasma rifle away by
pressing B. You are left with the Needler as both your primary and secondary weapon.
# Using a destroyed machine gun

You can use a destroyed machine gun; for example, in Zanzibar after you fire a rocket to
one of the turrets on the left and right on the main base. Just go back to them and the
screen will prompt you to hold X to operate. This can be useful during heated sessions.
# Hijack a Bansee

Wait until a Banshee drops quite low (but you still cannot reach it). Jump before doing
it. If it does not say "Hold X to board enemy Banshee", press X regardless. You
might not see Master Chief leap up and hit the Elite (or other alien) out of the Banshee.
Do not go too low, and drive slowly because the Elite might kick Master Chief out.
# Hijack a Wraith

Go near a Wraith and press X. Then, press B a few times. Instead of throwing a grenade,
just hop in. If this does not work, throw a grenade in the Wraith.
# Banshee tricks

When in a Banshee, press A and a direction on the Left Analog-stick. When in a Banshee,
hold A and press Left Analog-stick Down. The Banshee will do a backflip. Additionally, to
do tricks in a Banshee, press Left or Right on the Left Analog-stick and hold A to do a
barrel roll, or hold Down + A to do a loop.
# Ghost tricks

In multi-player-mode, turn on all vehicles and go to a place with open space. Get in a
Ghost and find a tank. Go towards it as fast as you can. You will flip and do different
things, depending on where you hit the tank.

Go to any level (Metropolis recommended, when you have to get on the Scarab). Back the
Ghost up to the side of the bridge. It will start hopping up and down.

Chose a level with the yellowish glowing boxes that blow up (Headlong or Waterworks
recommended). Get in a ghost and boost into one of the tiny boxes and you will be sent
flying. You can repeat this as many times as desired, or you can pile the boxes and be
blown sky high.
# Spectre tricks

When using a Spectre, go at top speed and hold A. You will do a wheelie for about three to
four seconds. This is useful when climbing up walls or going over short walls.
# Stealing vehicles

When playing a multi-player map with vehicles, you can steal vehicles such as the Wraith
from your opponent. Approach the vehicle while holding X. Note: This removes your opponent
from the vehicle only; you must press X a second time to board the vehicle.

To hijack a Wraith, you must get up close to it by first destroying the side guns. You
will get a message to press X. Do so, and you will be hanging on the side of it. Then, tap
B to punch the door in. Next, press L and throw a grenade in. Jump off and go back in by
pressing X, and you will now be driving the Wraith.

When you board a Wraith of Scorpion tank, the "B to melee" message will appear.
Melee until the cover is knocked off, then continue punching. This will kill the driver
without damaging the tank.

Use the following trick to knock enemies out of vehicle safely. Note: This only works with
a fast moving, non-flying vehicle. First, stand by a wall or something that they can crash
into. Try to get the opponent to run you over, then jump out of the way after about a
second of contact. He should then crash into the wall. When he does, go directly next to
it and hold X. You should now be in the vehicle.
# Snipe from vehicle

Piggyback on a Banshee. Before one member of your team gets into the Banshee, jump on top
of the Banshee's pilot cover. When you get in, you can just stand on top of it. Only make
turns with the Right Analog-stick. They are slower and do not tilt the Banshee. More than
one player can stay on top of the Banshee. This provides extra fun if you want to do
aerial tricks with friends by jumping from Banshee to Banshee.
# Piggyback ride on vehicle

With almost any vehicle, you can get a piggyback if you are not skilled at driving or need
a fast ride when someone on your team is already on a Ghost. This also works with the
Scorpion, Banshee, and the Warthog when you have someone in the gunner seat, when you are
all far enough away from the enemy.
# Vehicle explosions

In a multi-player level with vehicles (Ghosts recommended), stand in front of one of those
barrel things that explode. Wait until someone in a Ghost sees you, throws it in turbo.
and tries to run you over. At the last moment, jump out of the way. If done correctly, the
vehicle will shoot past you, fly into the barrels, and explode; killing the driver
instantly with a huge explosion.
# Send tanks flying

While playing on a map with two Scorpion tanks available (Coagulation recommended), have a
friend drive his or her tank up against a canyon wall until it flips upside-down, and your
friend falls out. Drive your tank over to your friend's tank. Face the side that looks
like a ramp. Line your tank up and start driving up it until one is on top of the other.
While you are still in the top tank, have you friend walk over to the bottom one. The
"Hold X to flip tank" message will appear. Once flipped, the bottom tank will
send the top one flying high into the air (sometimes above the level), spinning at
incredible speeds. After awhile, the tanks may start to catch fire and wear-down.
# Destroying a Ghost

To destroy a Ghost in one hit (sniper rifle) or three shots (battle rifle), look on the
left side of it, just under the driver's seat. You will see a gas tank of sorts. If you
shoot that directly, the Ghost will explode with one hit or one burst from the battle
rifle.

One of the best ways to take down a Ghost is with a sniper rifle. Wait until the Ghost is
facing away from you and open fire at the pilot. If the pilot does not die, the Ghost may
explode, because it is very vulnerable in the back.
# Destroying a Wraith

Besides boarding, there is one other reliable way to take down a Wraith in single or
multi-player mode. Get a Ghost and hit the booster until you are right up against the
Wraith. Then, circle around to the back of it and open fire. By the time he has fully
turned around to get a bead on you, he will probably be dead. If he tries to get out, you
can simply pick him off as he is climbing out. Note: This may not work as well in single
player mode, as the Wraith has anti-infantry plasma cannons.
# Next generation Warthog launch

This trick is reminiscent of the Warthog launch from the original Halo, but uses different
methods. First, start a split screen multi-player game with just yourself on a map that
has any explosive boxes (Headlong or Waterworks recommended). Then, find any of the
explosive boxes and gather them in a pile near one end of the map. You can move them by
pushing against them or meleeing them. However, do not melee them more than once or they
will explode. After you have gathered enough, park a Warthog over them slowly and fire a
rocket at one end of the Warthog. Depending on how many boxes you gathered, the Warthog
should go incredibly far. Note: This takes a lot of skill and time, and should only be
done if you have nothing else to do.
# Rewards for straight killings

The following is a list of rewards you get from killing people without dying once. Note:
After 25 it starts over again with "Killing Spree".

      5: Killing Spree
      10: Running Riot
      15: In The Zone
      20: Unreal
      25: Unfreaking Believable 

# Melee combo

When caring an item (bomb, flag, etc.) quickly press Melee, X, Melee to perform a combo
melee attack. Continue pressing Melee, X, Melee, X, etc. to make the combo continue
indefinitely.
# Melee, shotgun, melee combo

While equipped with shotgun, get in close range and press Melee, X (reload), Shoot, Melee.
Note: You must press X immediately after the first melee is finished.
# Plasma rifle, melee, shoot rage combo

While holding the shoot trigger, press Melee, and immediately after the hit, press X
(which instantly continues you back into shooting). Note: This can be done as long as you
do not overcharge the plasma rifle.
# Double whack energy sword combo

When using an energy sword, press Melee, X, Shoot. This combination can happen very fast.
# Infinite energy sword ammunition

When the energy runs out, do not trade it for another weapon. When you get to the next
level, try to use the sword. The ammo will be at zero but you will do full sword damage
instead of melee damage and can do sword moves.
# Instant kill

To instantly kill any enemy except Hunters and Bosses, hit them in the back with any
weapon.
# Easy kills

The plasma sword is one of the most deadly weapons in the game. However, there is a way to
make it deadlier. If you are walking up to someone, you will see the aiming reticule turn
red. If you press the trigger or B, you will deliver a deadly lunge that can kill almost
anything in one hit. To make this even deadlier, before you reach your enemy jump and keep
aiming at him. When the reticule turns red, you will still be in the air. As you are in
the air, press the trigger or B and you will lunge forward in mid-air. This is more deadly
because you are above himm and his head is the closest thing to you when you are in mid
air.

Get two Magnums (pistols) and shoot one trigger at a time. Do not use against the Flood,
as it will backfire and kill you.
# Sword cancel

To sword cancel, rapidly press B + X. This will let the sword swing wildly and is also a
good way to shock opponents. To swing your sword at an enemy but not hit them (canceling
your attack) press R + X. This will only work when you are locked on an enemy.
# Faster reload

When reloading a gun, press melee immediately after the ammo is reinserted into the gun,
press X. This enables you to shoot and/or zoom instantly. This works for any gun that uses
ammunition.
# Accurate SMG Dwing

When DWing SMGs, press one shoot trigger at a time simultaneously. This disables the
reticle/aimer from going upwards. Note: This also works on other DWings.
# Lock on with rockets

To lock on with rockets, target a person, vehicle, etc., then hold R until it says that it
is locked. The red reticle will follow the item. Release R to fire. Additionally, while
using a rocket launcher, you can lock-on to the following items: turrets, vehicles, and
the Phantom's plasma cannons (Covenant Dropship's turrets). To lock-on to those objects,
aim your cross-hairs at the object. By doing this, your rocket launcher's cross-hairs
should have four red squares on the corners. Then, hold Fire so that the rocket launcher
will fully lock-on to the object. While this happens, the lock-on system of the rocket
launcher should make a few repetitive beeping sounds. After the beeping sounds have ended,
the cross-hairs should be completely red and ready to fire. Release Fire and your
spiraling heat-seeking rocket launcher missile will go to the target.
# Switch grenade types

If you have picked up a frag grenade and a plasma grenade, press Black to change from one
to another.
# Practice with the sword

To get some good practice in with the sword, you must have two players, both with swords.
Practice hitting each other. This is useful for combat with the Royal Elites.
# Flying sword

Have the sword when an enemy is very close. You can jump and do it, or run and jump to
them, then press B. This is a one hit kill for Flood, and a two hit kill for some Covenant
and the shield Flood.
# Extra ammunition with dual wield weapons

Have two dual-wieldable weapons (for example, a Needler and an SMG), but do not have them
out at the same time. The Needler would be the weapon that you want extra ammunition for.
Have the SMG out and find another Needler to dual wield with it. Then, find yet another
Needler and trade that with your SMG. You will now have three Needlers, and have three
times the ammunition.
# Dual wielding recommendations

When dual wielding, it is best to think about things before you just grab a needler and a
plasma pistol, and have a pistol as your third weapon. You should make it so you have a
good backup weapon; when dual wielding, ammunition can go quite quickly. Have two plasma
rifles (or your choice) and have something like a particle beam rifle, shotgun, Covenant
carbine, or perhaps a rocket launcher so that you have something to fall back on. Some
suggestions are as follows:

      Needler x2
      Plasma rifles x2
      SMG x2
      SMG and a plasma rifle
      SMG and a plasma pistol 

Note: Having two plasma pistols is not a good choice because you cannot hold the two
triggers down, or you will power them up. You must keep pulling, making this somewhat
difficult. When wielding two weapons at once, use only one at a time, and when that runs
out of ammunition, use the other one while reloading. Do this to keep up a steady stream
of fire.

Dual needlers is probably the most underestimated weapon pairings available in the game,
and probably the most powerful as well. Needlers have an incredibly fast rate of fire, are
heat seeking, do initial damage then explosive damage, and you can pick up usually 80 to
160 ammo after each bout of gun fighting (in campaign mode). The only bad thing about
needlers is the fact that they ricochet off shields and some body armors (for example,
Hunters and the Elite Guard). They are not recommended for fighting shield wielding
enemies, Hunters, Elite Guard, or Infected Flood (as they are extremely quick and will
most likely do damage to you before the needler shots explode in them). In multi-player
mode with friends, there should be nothing more feared then dual needlers.

A great dual wielding combo are two plasma pistols. Early in the game, two blue ones will
do. Later in the game when you begin to fight the Brutes, after they die take their red
plasma pistols. The red ones are slightly more powerful and overheat a little bit faster.
A red and blue plasma pistol is recommended, as they compliment each other very well. If
you have fast trigger fingers, any enemy will die. Even Brutes will die within around five
seconds. Be careful; watch your heat and ammo meters. The plasma pistols are very good
because they are powerful, and get rid of energy shields very quickly.

Use the following trick for easy kills by dual wielding a plasma charger. Get one plasma
and any other weapon of your choice (SMG, plasma rifle, needler, etc.). Next charge your
plasma pistol and keep it charged. If you get a hit on your opponent, his shields will be
down and you can kill him within two seconds with a normal gun.

The best dual wielding combo is the plasma rifle and the sub machine gun (SMG). The second
best is dual SMGs, and the third best is a plasma pistol and pistol combo.

Dual wield a plasma rifle and a plasma pistol. While the rifle is firing you can charge up
the pistol, and while the rifle is cooling down shoot the pistol charge.

Do not be afraid to retreat for a moment to let your shields recharge and reload your
weapons, especially when dual wielding.
# Defeating Brutes

Get a Plasma Sword from a dead Covenant Elite and get close enough to the Brute for the
half-circle surrounding the crosshairs to turn red before attacking. You will lunge
forward and get rid of half the enemy's life. Jump into the air immediately afterwards,
and do this a second time to kill him instantly. Both attacks combined cost only ten ammo
points, so this process can be done ten times in succession, making it an effective way to
crowd-clear Brute patrols near the end of the game. Make sure to jump in-between each
strike so that the Brutes you are fighting cannot continue to ram you and drain your life.
Additionally, on the last level when you are fighting the head Brute, wait for his shields
to go off (when the blue gas-like thing around him shuts off). Then, shoot him in the head
as many times as you can until it turns back on. Repeat this process until he is dead. Do
not use an energy sword. It will not work, and he can kill you with one hit of his hammer.

When you are facing several Brutes together, such as in the Uprising level, use a weapon
with good accuracy, such as the pistol. However, this may be difficult because it no
longer has a scope on it. The Covenant Carbine is a good choice because it has great
accuracy, a zoom, and a usable clip size. When using the carbine, aim for the skull
plating they have on the top of their head. If you are a skilled shot, this should kill
the Brute in about four to five shots. Have something like the energy sword as a backup in
case there are too many and they charge.

Two direct head shots with a beam rifle are required if they are wearing a helmet. Pack
some heavy artillery. A fuel rod cannon or rocket launcher may be cheap, but they cannot
charge you if they are blown up. A few hits with the brute shot can also work; there
should be plenty of ammunition for it. If all else fails and they charge, a shotgun or the
blade on the brute shot can work, but it will require three shots to the face with a
shotgun and three hits with the blade.

The best combination of weapons against a Brute is to use two plasma rifles. Brute plasma
rifles are recommended, as they are slightly stronger and shoot faster with a slower
heating process. Run up to any Brute (this actually works for all enemies except Hunters)
and fire both of your plasma rifles in sequence. This means that first you fire the right
(or left) gun until it is nearly overheated, then stop firing that one and begin firing
your second one until it is nearly overheated. Again, start firing the other one. Keep
doing this in sequence and the only thing that will stop you from shooting is running out
of ammunition. A good way to do this properly is to count how long you have been shooting.
Shoot with one gun at a time for about three to five seconds, then begin shooting the
other one. This is very useful for big groups of opponents as you do not have to reload or
wait for your weapon to cool down.

On the final level, once you reach the door that leads to the final battle, a group of
Brutes will come out. Instead of fighting them, use your invisibility gear and sneak
through the door without having to fight. Note: You must be fast or the door will lock.

The Brutes' weakness are their heads. That is why they usually have metal plates. Shoot
them in their heads for an easy kill.
# Defeating Elites

When battling with Elites, do not hit them once with your weapon. Always hit them multiple
times. If you hit them once, they will have a faster time and kill you with one hit or
take down your shield. Additionally, an easier way to kill Elites quickly is to
double-wield the SMGs and aim for the head. Be careful, as the SMGs tend to send the
reticle upward. Also, try meleeing him before using the double strategy.

You can outsmart Elites in some battles by finding cover and returning fire as usual.
However, when they stop firing, relocate to other sources of cover and have a few seconds
before they notice. Also throw grenades before they get all the way out, if they are
appearing from a door or a ship portal.

Dual wield a plasma pistol or rifle and a Human pistol. Use a plasma pistol or rifle to
knock down the shields quickly, and then shoot them in the head with the magnum.

The best way to quickly kill an Elite is to hit them multiple times with your weapon.
First. hit them so they are stunned for a few seconds, then shoot them quickly. They
should die easily.
# Defeating Floods

Get a Plasma Sword from a dead Covenant Elite and get close enough to the Flood for the
half-circle surrounding the crosshairs to turn red before attacking. You will lunge
forward and kill the enemy instantly, sometimes killing two or even three if they are in
close-enough proximity to the target. This attack only uses between two to five ammo
points, so it can be repeated at least twenty times. Note: Do not use this trick on either
the small spider-like Flood or the large bulbous Flood, as the explosion that follows will
damage your shields. Additionally, to kill the Flood easily, use the sword. It cuts right
through the Flood in one shot, unlike any type of plasma gun.

To make fighting Flood easier, use a shotgun and an energy sword. The Flood levels are
mostly close quarters -- shoot them in the face with a shotgun. This will take down even a
shielded Flood in one hit. Then, use an energy sword to vaporize the bodies so that they
cannot get back up. The best part is that it will not use any energy sword power.

You can actually kill the human and elite Floods with one shot of the Covenant carbine.
Aim directly at the stomach for the human-type Floods (with no long tentacles in their
left arm); and aim high in the middle where the head would usually be for the Elite-type
floods (with the long tentacles).
# Defeating Grunts

With big groups of enemies, kill off the Grunts first, as they are easier to kill and
become less of an annoyance. Additionally, two slashes with the plasma swords are good
against Grunts. However, hitting them with the grenade launchers three times can kill just
as easily and does not use any ammunition.

Get a needler. Find a grunt and aim close to his head. Shoot him and he will jump in the
air and die.
# Defeating the Heretic Leader

It is best to have dual Needlers and a Sentinel Beam when you are playing under the
legendary difficulty setting. As soon as game play resumes after the intermission
sequence, press White to turn invisible. Then, press Y to get rid of one of your guns and
stick a plasma grenade to one of the guys. As soon as you do that, run to the left and
behind a column. You should see a hole/hallway kind of thing. Go in there and hide a short
time. You can then run out of the hole, turn invisible, and stick another grenade to one
of them. If a grenade explodes and you hear a grunt or yell, you have hit the leader and
not the copy. Go back and hide in the hole. This will save a checkpoint. The guy will
start talking and more copies will appear. Repeat the process until he is dead. Note:
Whenever you kill a copy of the Heretic Leader, it will drop several grenades, allowing
you to restock.
# Defeating Hunters

Get a beam rifle (the Covenant sniper rifle) and fire it in the middle of their bodies
where it is pink. This is more effective then pumping shell after shell into them. Because
they have the new gun, getting close to them no longer works. There is another way to
defeat them, but it is more costly. First, take your plasma grenades and throw about two
or three of them on their pink skinny area. Then, get a shotgun (or the strongest gun you
have) and pump the pink spot full of rounds until it is dead. Since they usually appear in
pairs, this can waste a lot of ammunition and grenades.

You can kill Hunters without using any ammunition. If there is a Human turret nearby, use
it. You will do so much damage that they will drop quickly. You can also still get close
to them. Remember that you are a lot faster than they are, and pay attention to where the
other Hunter is located. Sometimes you can get them to hit each other. It is also possible
to melee attack them to death, but a lot of your Marine allies will probably die.

When you encounter a Hunter on any level, use your melee attack and hit them in the head.
They will stand there for a moment, stunned. This is just enough time for you to get
behind them and kill them. Depending on how skilled you are, it may take a few times to
take them down.

When you see a Hunter, find a turret close by. Man the turret like in the Outskirts level.
You must kill two Hunters to move on. There will be a turret upstairs, and when they come
out, open fire on them.

When a Hunter charges, move out of his way. When he misses you, the pink spot on his back
will be wide open. Use the weapon of your choice to blast him.
# Defeating Prophets

To kill Prophets, you must dodge there laser attacks and get up close until the message to
hold X to board appears. Do so. Once onboard, tap B to attack them. Three hits should kill
them. If not, repeat until it falls.
# Defeating Regret

To easily defeat the prophet Regret, jump on his vehicle then hold X to board it. You can
then press B to melee him to death.
# Defeating Royal Guards

To easily take down Royal Guards (red Elites with strange helms), attack them with the
energy sword. Do not be afraid -- keep slashing. They will fall after about three hits.
Note: If it has a energy sword, you must get the first hit or it can kill you with one
shot. Do not let their armor fool you -- they are still Elites. Knock down the shields
with a plasma weapon, then shoot them in the head with the pistol.
# Defeating the Scarab

Instead of following the Marines, go staight across the bridge. You will find a sniper.
Take it, then jump on the Scarab and shoot all the Elites and pilots. Additionally, if the
people on the Scarab are taking down your shields, get on the gun turret. Fire at them
madly. They will hide and allow time for your shields to recover. Then, jump on the Scarab
and blow their head off by surprise.

When you fight the enemies on the Scarab, mostly Elites and Grunts, start running down the
path. You will see rocket launcher ammunition. Collect it if you have a rocket launcher,
as it will make battle easier when you enter the Scarab. Your second weapon should be a
shotgun or dual plasma rifles in case you lose rocket launcher ammunition.
# Defeating Tartarus

When playing in co-operative mode under the legendary difficulty setting, get a grenade
launcher that is left over from the Brute on the bridge. When Tartarus jumps onto the
spinning disks, jump onto the platform with your partner, then jump on the three disks for
safety. Let your partner have a carbine rifle on the top level and have him snipe
reinforcements when they arrive. Run around the middle circle, waiting for Tartarus to
lose his shield from Sarge sniping him. Hit him with your grenade launcher. Hit him three
times, then run away and wait. His reinforcements may appear. If they do, camouflage and
run to the top level. Allow your partner to kill the Elites. Camouflage if Tartarus or
Elites come to the top level. Note: Use your Brute plasmas if you run out of ammunition.
There are some on the middle level, and perhaps the bottom level. Make sure your partner
conserves his carbine rifle ammunition. Never fight a Brute Elite, as they will kill you
in a few hits. Also, never hit Tatarus with a melee attack. Never use grenades as Tartarus
will just jump. The most important thing is to not allow your partner to die. When doing
this in single player mode, use the same tactics except when Elites arrive, camouflage
yourself then go to top level and snipe with the carbine rifle.

When the intermission sequence ends, do not rush towards Tartarus like the others.
Instead, just wait until they all jump to the other side, then jump over there. Or, you
can wait for the moving platform to help you get to the other side. After you have done
that, Tartarus will have a sort of "fog" around him. Get a plasma gun. Note: If
you cannot find one, go to the lift, and on the top floor behind a wall there should be a
box from which you can get one. Dual wield the plasmas and fire at him until the fog goes
away. Then, keep shooting at him with the plasmas until he dies. Alternately, when his
shield depletes, drop your gun and throw a grenade until he dies. Be careful though --
stay a good distance away to avoid being hit and killed.

When playing on the legendary difficulty setting, instead of getting out of your Banshee
when entering Tartarus' base, fly it inside and up, using the boost. You will scrape the
ceiling and run into the wall at the end of the tunnel, then run into the door. Get out,
open the door, and take your Banshee inside the door. Kill the Covenant with it, or get
out then keep flying through the doors. When you get to the intermission sequence, you
will be out of your Banshee on a platform with Tartarus in front of you with some Brutes.
Kill them, then turn around and go back down the hallway the intermission sequence
skipped. Your Banshee will be sitting there, ready for takeoff. This makes defeating
Tartarus much easier. Continually fire at him and when the sergeant takes out his shield,
it will hurt him until the point that he dies. If he tries to jump on you, just boost
under him. Watch out for his Brute friends that he calls -- they are very accurate with
Brute shots and plasma grenades and will kill you. Also, do not fly under the platform.

Get two Brute plasma rifles and run away. When his shields are down, throw grenades then
shoot him. He should die quickly.

In the last level of the campaign called The Great Journey, get to the part where you
enter the control room. Instead of walking through, bust your Banshee through. When you
enter the room with the Brutes, get out of your Banshee and kill them. Note: They might
destroy your Banshee. Then, kill the Honor Guards. Make sure your Banshee is in the room
where you fought the Brutes. Continue on foot until the intermission sequence starts. When
it ends, turn around and run back. On your way through, your friends will teleport there.
Keep going and get in your Banshee. Note: Do not go below the last platform levitating in
the main room or the game will automatically kill you. Then, drive your Banshee to
Tartarus and shoot him. Pressing B will shoot your bomb. When his shield gets down, shoot
him as hard as you can.
# Defeating hijackers

Use the following trick in multi-player mode with someone that is trying to steal your
vehicle. When you definitely know that they are trying to board your vehicle, press X to
hop out as they board. This will give you about three or four seconds to blast them before
they can get a bead on you. This requires some skill, but works very well. It is possible
to take out a Banshee, Ghost, and Warthog with one SMG by doing this.

When someone tries to steal your vehicle (and it is not a Banshee), allow them to do so.
When you hit the ground outside the vehicle, press X as fast as possible. You should steal
the vehicle back from the person. Move quickly away from them or they will do the same
thing to you.

When someone is hijacking your Ghost, Warthog, Specter or Banshee, wait for them to almost
take it away from you (just before you lose control of it). Press X quickly to get out,
then immediately after you press X, hold X. You will ditch your Ghost or other vehicle,
and will not kicked off and can now hijack it back.
# Defeating opponent that has an energy sword

Your best chance of killing your opponent before he slashes you is to dual wield SMGs.
When you see the enemy from a short distance, just let loose. The bullets will most likely
stop the enemy from advancing and will kill him.
# Grunts Birthday Party mode in The Arbiter

Play the mission on the legendary difficulty setting. Proceed until you reach the first
Banshee section. Immediately fly straight down to the bottom of the level. Search the
cracks where the large cylinders connect to the station to find a circle of Grunts dancing
around a skull. Get the skull and the words "Grunt Birthday Party" will appear.
When you get the skull, all headshots that kill the enemies will cause them to explode as
if a plasma grenade were attached to them. This works well if you aim for a Grunt in the
middle of a group of enemies. Also, this may only work for projectile weapons, but does
work for the Covenent carbine and the Covenent sniper rifle.
# Run extremely fast in The Arbiter

On the first Arbiter mission, go to the Banshee part. Find a steeply slanted beam. Fly to
it get off and go up to the top. Jump once, and once you land, jump again. Do until you
die and it will look as if you are running down the beam very fast.
# Skull in Armory

Complete the mission orders until someone asks you to go in the elevator. Wait until he
says "Will you come in if I say please?" and walk in. When you get into the
tram, face the Earth and hug the wall. Hold X for the entire ride. Eventually you will
pick up a skull that says no clue to what it does (no word will appear, as with the other
hidden skulls). Note: You cannot keep it as a weapon, as it is taken away after the
intermission sequence. However, you can beat up the man with it.
# Easy completion in Armory

When playing on the legendary difficulty setting, get to the part where you are in the
shuttle bay where the Covenant have boarding craft attached. You can complete this level
two ways. The first is to kill the Grunts with the battle rifle, then pick up a plasma
pistol. Use the plasma pistol to lower the Elite's shields, then quickly take out the
battle rifle and kill them before they take cover. The other method is to get a number of
plasma grenades and stick them on Grunts. They will run to the Elites and kill them.
# Sniping locations in Ascension

There is a great sniper location in the Ascension multi-player level. Get the sniper rifle
and an SMG or a rocket launcher and grab the Banshee. Fly to the space between the two
slanted forklift-type things immediately above where you would start if you were player
one. Land, and get out. The Banshee will probably fall. Run up the slanted area and you
can see the entire field. Because you cannot die from high places, you can drop down for a
reload then fly back up.

Take the Banshee and park it on top of the tower with two beams coming out of its top.
There should be a good location for your Banshee at the beginning of the two beams. On a
team, have one person takes one and the other use the other beam. Remember to go to the
end of them to get the best view. If you are alone, you have an advantage. If someone
starts shooting at you, you can jump to the other side. You should be too far away for
them to notice. If you fall off, take the rocket launcher or duel SMGs to protect
yourself.

Use the Banshee and fly up to the two poles above Sniper's Roost. Make sure you have a
sniper rifle.
# Fly very high in Ascension

Play the Ascension map in multi-player mode. Take a rocket launcher and before you go on
the thing that shoots real high in the air, shoot downwards. You will fly up twice as
high, but will be dead.
# Hidden weapon in Battle Creek

Go to the Blue base. Run to the end of the base where the ramp is located. Tilt your gun
to the bottom in the "northeast" direction. You should see the "Hold X to
pick up weapon" message. Hold X to pick it up. This is a hidden weapon which is
useful when cornered without any ammunition.
# Hidden message in Beaver Creek

In multi-player mode, go to the sniping location where you are able to push the rocks down
in to the creek. Roll down all the rocks and look at the spots along the wall where the
rocks were placed. You will find a message that reads "Why am I here" with
someone's initials under it.
# Fall through level in Beaver Creek

Play the Beaver Creek map in multi-player mode. Go up to the sniper rifle and walk across
the edge so that you are behind the rocks. Turn to your right and look at the tree in
front of the sniper rifle area. Jump and land directly in front on the tree. You will
sometimes fall through the level and the game will say that you were killed by the
guardians.
# Sniping location in Blood Gulch

At the Red base, get a Banshee. Get on top and face toward the Blue base. Turn right and
go over. Follow the wall up and close to the top. You can get out there and snipe from
this location.
# Get on top in Burial Grounds

Use the Ghost or a miss with the energy sword to get up on the level. You can walk around
the dunes, but invisible walls will stop you.
# Sniping location in Burial Mounds

There is only one sniper spot, and one turret. If you are on a team, try to stay in the
turret and on the following sniping spot. When you are alone, just take the sniper spot.
To get to this sniper spot, take a Ghost and use boost to get on top of the sand hill on
the side of the level, around the purple machine things.
# Get on top of level in Cairo Station

When you get to the air lock part where the screen enters a cinematic view and the phrase
"Authorized personnel only" appears at the bottom of the screen. Elites with
jetpacks will come to attack you. Run past the flying Elites. Run out into space where in
front of you is a pillar that slants upward. Walk all the way up to this pillar and jump
on it. You should now be on the pillar's slanting portion. Walk up the pillar and you
should be on top of the ship. Turn right and go straight until you pass two hallways to
the right of you. You should now still be on the silver-brown part of the ship. At the
very end of it you will see your path slant to the right slightly. You now can see that
the only place to go is on the blue part of the ship. Jump from the silver-brown part of
the ship to the blue part. Look to your right and you should see a upward path. Climb it.
If desired, you can go sightseeing to your left "towards earth"; there is
nothing but the cannons of the ship. Once up on the elevated part of the blue ship, you
will see a gap between the blue ship and the silver-brown ship. Jump on the silver-brown
part of the ship. Once on there, run towards your right. Do not go down the orange glass
plated window that slants down; this will leave you at a dead end. If choose to go that
route, there are pillars here that will allow you back up, like on the first step of
getting up on the ship. You will come across orange windows. You will fall through some of
them, but not enough to not be able to get back up (simply a few feet). You can look down
into the ship from the top plated part of the glass. Jump out of these if you come across
many of these non-solid pit holes. Some orange plated windows laying on the ground that
have force fields. Hold Forward and jump to clear them. This can go on for a very long
time.
# Marine in machine in Cairo Station

Go to where the bomb is. Go out of the elevator and turn directly to your left and move
down the hallway. Turn right and you should see no enemies, but a Marine. You will need to
do this quickly. Push him up the stairs, but do not attract the guards. This will make him
move. Then, push him into the ammo feeder and watch him get pushed into the wall. He will
disappear. Note: If you do this, you will die and fall through the level or land on other
platforms you previously visited, like the Pelican in the hangar.
# Johnson's cigar in Cairo Station

In the first level, as soon as you get off the lift do not go on the train. Instead, look
to your right to find a trash can. Go over to it, crouch, and look in between the can and
the wall. There should be a Johnson Cigar burning away. Additionally, go to the armory. As
you are coming up the stairs, you will hear the man shooting his shotgun and talking. Kill
the Elites and go through the door. Jump over the turret and look to the right. Jump on
the lights sticking out of the wall, then jump over the rail. Get on one of the beams and
jump off it onto one of the rails. There will be a small room with no doors. Jump onto
that and bash the trash can. When you look on the floor, you will see Johnson's cigar.
# Johnson floating hat in Cairo Station

After things start and you are getting some weapons, go down the stairs. You will see a
hat on a box of gear. Melee attack the box from under the hat, and it will float.
# Sniping locations in Coagulation

The best sniper spot is at the Blue base (the one with all the shadows), on the rocks
above. Fly your Banshee there and land on a flat rock. You will be covered by shadows and
have a view of the entire level.

Near the Blue base there is a sniping location at Mt. Erectus. You can get up there with a
Banshee, Ghost or a Specter.

At the Red base, get a Banshee. Get on top and face toward the Blue base. Turn right and
go over. Follow the wall up and close to the top. You can get out there and snipe from
this location.

Find a Banshee and a sniper rifle. Fly to the Red base. Turn so that you looking at the
Blue base, and then look to the right. You should see the boundaries. Fly over to the wall
and you should see a slant. Land on the slant and you should be able to snipe from there.

Go to the Blue base and when looking towards the Red base, look to the right. You should
see a shadow from a big piece of rock sticking up. This is a good sniping spot, because
when you are in danger you can hide behind the piece of rock sticking up. A Banshee is
needed to reach this location.
# Banshee snipes in Coagulation

Get a Banshee and fly directly behind the Blue base. Land up there, then get left (behind)
the Red base. Then, get in the peak of the rock point by the Blue base.
# Ride the walls in Coagulation

Take a Spectre, Ghost, or Wraith and use boost to get behind the Red base. Ramp over any
ridges and rocks. Go up on different rocks and ride along the walls sideways.
Additionally, on the right side of the Blue base, take a Ghost and boost at the wall.
There is a location that lets you drive straight up the wall. This trick has no strategic
advantage, because as soon as you hop out of the Ghost both you and the vehicle will fall
down.

Get a Ghost and ride into the wall while holding A. You will begin to go straight up the
wall. This only works in some places, like behind the Blue base and slightly to the left.
# Get near top of level in Coagulation

Play a game at Coagulation and make sure you have Ghosts. Play as the Red team and get a
ghost. Get on the hill behind the Red base. Lean up against the right side of the lower
rock (if you are looking at the Blue base). Turn slightly uphill until you see a vertex
where the land goes upward and meets the cliff. Face it. Strafe right about five game
feet, but do not move your aim. Press L and hold Forward until you reach the top. You may
need to turn slightly once you Ghost moves up the wall a short distance.
# Run on air in Coagulation

Set the game so that the main weapon is the energy sword. Get a Warthog and put it at one
end of the level. Have one person get in the passenger seat and look at the other player.
When you lock on, hold R. Then, have the second person to go to the other side of the
level. Have the other player hold X. When the player gets out, he will run in air. He will
run until he gets above the other player. If you are skilled, you can get the player on
the top edge of the level.
# Boost high into the air in Coagulation

This trick requires a Wraith with overshields on. Locate the rock that sticks out. Stand
up against the wall that sticks out and have someone hit you with the Wraith when they
boost. If done correctly, this should shoot you extremely high in to the air. This also
can work on almost every map with a wraith, but you must have oversheilds on to avoid
getting killed.
# Fly to rock in Coagulation

Get a Warthog and face the passenger seat to a rock far away. Get a sword and get in the
passenger seat. Then, have a person out of the Warthog stands by the person in the
Warthog. The person in the Warthog must lock on, and when the reticule turns red, attack.
It will make a sound. The person who is out of the Warthog should get to the rock and
stand on it. Then, have the person in the Warthog get out. They will fly across the
stadium to the person on the rock.
# Spinning tanks in Coagulation

This trick requires a Wraith, a Scorpion tank, and oversheilds to be turned on
(recommended). Have the Wraith and the tank ram each other. As they hit, have the person
in the Wraith hit the turbo. This should glitch the tank and cause it to start spinning
uncontrollably and bounce off of a lot of things. this glitch is alot of fun to do but it
can be hard to do.
# Grenade does not move in Colossus

Throw a grenade on a conveyer belt. It will stick to the ground, but not move with the
conveyer belt.
# Envy mode in Delta Halo

Play the mission on the legendary difficulty setting. Continue until reaching the area
during the "push through the covenant held ruins" phase where a landing zone for
the Pelican to drop weapons must be cleared. When you reach the area where Cortana says
"They're pouring out of the center building", note the plasma turrets along the
borders. A short distance after the turret on the left side is the outline of a sealed
door in a wall. There is a rock in front of the door. Jump on the rock, then jump onto the
ledge above the door. Next, jump to the ledge to the left. Then, grenade jump onto the
building with the sealed door. On the roof of the building are two dancing Elites and a
skull. Get the skull and the word "Envy" will be displayed. You can now use
active camouflage.
# Warthog in Delta Halo

In the beginning of the level when you are storming the hill, it may be tempting to pass
by this part. However, stay in that area until you survive both waves of Covenant that the
Phantoms drop off. A Pelican will appear afterwards and drop off a Warthog for you and
your teammates.
# Flying tank in Delta Halo

Drive the tank around until you get to the part with all the stationary Covenant shields.
Blow the shields up then quickly park the tank on several of them. Get out of the tank and
then watch as the shields reform. The tank will fly, doing spins. This is even more
enjoyable when you are in the tank. You will die when in the tank and it flies very far.
You can also try this with other vehicles.

Get the tank and go to the area with the big castle in the middle, where you get men and
ammunition. Bring the tank up to the shields (four or five), and shoot the shields with
the main cannon. Go onto the shields and wait until they respawn. You will see the tank
spin very fast and go very high. Note: You will die and respawn.

You will get the Marine tank after activating the bridge. You will reach a structure which
the Marine will point out is the second structure. After you hear one of the Marines say
"A pelican is coming in. Let's clear an LZ", you will come up on some Covenant
hiding behing about six or seven lined up shields. Destroy all of them, then wait for the
shields to reappear. Then, shoot them all to make them deactivate. Immediately park the
tank across as many shields as you can. Get out, stand back, and the watch the tank fly.

Acquire a Scorpion tank. Then, proceed with the mission until you reach the ruins of a
complex. Slaughter all the Covenant, then reach the top platform where the energy shields
are located. Knock out the shields, then drive your tank on top of them. Position it
correctly, and when the energy shields appear your tank should go flying through the air.
# Get on top of the level in Delta Halo

By doing this trick you will be able to drive around the mountainous rim of the entre
level and to actually drive or walk under the water and all the structures. After crossing
the drawbridge and taking care of a few Ghosts, continue until you reach a courtyard with
a pond in the middle and a stone structure in the middle of the pond. For the next part
you will need a Ghost. At the entrance, turn to your right and you will see a few trees
sort of all clustered together. There is a stone wall there that you cannot jump up.
However with the Ghost, you will be able to get onto the green patch and beyond. Boost if
you need to and be careful going around the mountains. You can still fall to your death.
If you make it all the way to the opposite end of the level, you will find yourself on a
very flat piece of land.
