1. Prologue
I plan to do this faqs a little differently. Instead of giving heavy spoilers
and all that mess, I plan to simply answer questions on sticking points. For
example, I’ll ask, How do you solve so and so and I’ll answer afterwards.
Also, like always, this guide has its own legal exclaimer.
Update:
Some faqs authors believe I'm simply not giving substance. I believe
that the average pc gamer is smart enough to make his own computer let
alone find their way through linear parts. I just believe in addressing
legitimate sticking parts (namely those that hindered me and others).

2. Helpful tips
This game uses advanced physics like no other game before it. What
I mean is that the environment can, and most likely after you get the
gravity gun, will be your secondary weapon. Here’s some
things to remember before going far in this game.
- Watch out for Headcrabs. They are everywhere.
- Barnacle tongues can be useful for getting to high ledges.
- Flammable barrels should NOT be grabbed and pushed by the gravity gun.
Just kidding! This is a VERY useful tactic.
- Using grills and barrels as bullet shields saves your life in Nova
Prospekt, or anywhere for that matter.
- If you can run away, do so.

4. Monsters
- Combine Soldiers: These hapless souls are simply humans who have
given up on life and work for the Combine themselves. They range from
easy to hard, depending on what weapon they are using. They use all
sorts of weapons: Pistols, Energy rods, fists, Shotguns, and Pulse Rifles as
well as Magnums and Grenades.
Difficulty: 1-5 to 4-5.
- Combine Elites: All of them use Pulse Rifles as well as the
secondary function on them. They also have reinforced white armor
and can take a beating.
Difficulty 5-5.
- Headcrabs: As annoying as usual. Hops up, Slice, dice, hide in
boxes, corners, come off the faces of Zombies. Their difficulty
is based on their element of surprise. Difficulty: 2-5.
- Black Headcrabs: These tough guysdrops your health to 1 in one
bite and take a little to kill. However, your suit gives you
a neurotoxin that brings your health back to whatever it was.
What makes these guys difficult is if they have standard headcrabs
with them and they drop you to one.
Difficulty: 3-5.
- Barnacles: They are pushovers who grab you with their tongues if
you run into them. What makes them a pain is that at points, they
are clumped together.
Difficulty: 1-5.
- Zombies: The zombies are pretty easy, slow moving, and susceptible
to head shots.
Difficulty: 1-5.
- Zombie Hulkers: They are humans who have been taken over by the
Black Headcrabs and they have up to 4 of them on their bodies. Also
they fling them at you too.
Difficulty: 3-5.
- Zombie Runners (Leapers): These skinny alien monsters are fast, climb poles,
and are relentless.
Difficulty: 3-5.
- Scanners: They are the flying orbs that follow you and relay your
position to Combine
guards. Difficulty: 1-5.
- Manhacks: These little orbs have rotating propellers and attack
you. You’ll know one’s near when you hear a loud whirring sound.
Difficulty: 2-5.
- Gunboats: Tough, tough, tough. RPG’s are the only things that
can take them down. They are fast and can take you down quickly.
Difficulty: 5-5.
Suggestion by Roman G.
I found this strategy very useful against gunships. You know how
they shoot down rockets from your RPG? Well, here's a suggestion.
Instead of firing all those rockets and having them shot down by
that huge machine gun, wait until the gunship strats firing... at
you, your rebels, antlions, etc. Once it starts firing, shoot the
rocket! It will ignore the rocket completely, giving you a free hit.
Have fun!
Roman G
- Helicopter: These things drop mines and shoot pulse rifle charges at
you.
Difficulty: 3-3
- Mortar Tanks: Tough tanks that can level you in a few shots.
Difficulty: 4-5.
- Antlions: Fast, brutal, and they attack in packs. If you have the
unfortunate luck of fighting them, cry when your weapons go empty.
Difficulty: 4-5.
- Antlion Guard: This bad boy is a toughie who can take hits and runs
at you as an attack. Sidestep him and he’s cake. He gives you your
Antlion Lure.
Difficulty 3-5.
- Striders: These things are Tri-legged 50 foot tall monstrosities
that are just…a pain to take down. They take at least 8 rockets on
Normal mode to take down. They have a pulse rifle
and a reality distorting beam as well as they can impale you.
Difficulty: 5-5.
- Turrets: Annoying things that can be knocked over.
Difficulty: 2-5
- Dr. Breen: The Central Antagonist. He is responsible for the post-
apocalyptic nightmare that has become Earth.
Difficulty: 3-5
5. Weapons
- Crowbar: The trusty crowbar from the first Half-Life. It is a pretty
useful headcrab killer and is the second best for killing Manhacks.
Attack Power: 3/5
Stopping Power: 1/5
Speed: 5/5
- Pistol: It is a simple gun that is useful for situations but, not
something you want to rely
on unless you have to.
Attack Power: 2/5
Stopping Power: 1/5
Speed: 5/5
Reload Speed: 3/5
- Magnum: A powerful gun that can kill almost all enemies in one hit.
Attack Power: 5/5
Stopping Power: 4/5
Speed: 2/5
Reload: 1/5
- Submachine Gun: It’s a fast shooting weapon but it’s rather weak in
overall power. Its secondary is a useful explosion.
Attack Power: 3/5
Stopping Power: 1/5
Speed: 5/5
Reload: 3/5
- Shotgun: Spread Fire? Power? Nice! Its secondary function is a
double power shot that can floor almost anything.
Attack Power: 5/5
Stopping power: 5/5
Speed: 2/5
Reload: 2/5
- Pulse Rifle: This is a machine gun that has a very powerful fire
power and is very fast too. Its secondary is a powerful plasma bomb.
Attack Power: 5/5
Stopping power: 1/5
Speed: 5/5
Reload: 4/5
- Crossbow: The equivalent of a sniper rifle. The secondary is a zoom.
Attack Power: 5/5
Stopping power: None. It either kills instantly or seriously maims.
Speed: 4/5
Reload: 5/5
- Rocket Propelled Grenade: It is a rocket launcher that shoots
user directed rockets.
Attack Power: 5/5
Stopping Power: See Crossbow.
Speed: 2/5
Reload: 1/5
- Grenade: An explosive that can be thrown. Secondary attack
is pulling the pin before throwing for premature explosion.
Attack Power: 5/5
Stopping Power: None.
Speed: 3/5
Reload: None.
- Spore: This can be used in the sand traps stage and
Nova Prospekt to summon the Antlions as your servants. The primary,
when thrown, directs the Antlions toward the object of attack.
The secondary is that they come to your side and follow you.
- Gravity gun: This useful weapon manipulates boxes and other
movable objects, pulling them to you, as well as propels them with a
forceful push. Surprisingly this gun can be used to kill headcrabs
and not only kill Manhacks but it can be used to make Manhacks
portable shields AND a spinning weapon of death.
Attack Power: None.
Stopping Power: None.
Speed: 5-5
Reload: None.
Alternate Strategy by Henrik:
IMO the gravity gun is the best for taking out manhacks, they often
explode at the first burst if you let them get close.
You can do the same thing with scanners also.
And to save ammo, it can be used against the headcrabs.  Three hits
and they are dead (in normal difficulty). And they are stopped nicely
;-)
- Gravity Gun Redux: In the final two levels, your Grav gun becomes
an unstoppable weapon of mass destruction. It can pull heavy items,
propel them and even pull Combine guards to you. It can also
shoot a massive ray at close range that incinerates weapons and kills
guards instantly.
Attack Power: 10/5
Stopping Power: None.
Speed: 5/5
Reload: None.

“Point-Intersection”
Length: Very Short
Fun Factor= 4
Rise and shine Mr. Freeman. It’s time to wake up.
1.1: What do I do now?
- Get off the train and follow the people on it. It should lead you to a
turning door. Enter it from the left side (This IS Europe after all), and
find your way to the Security door.
1.2: Should I enter Nova Prospekt?
- No. The Combine guard should lead you to his office.
1.3: Oh wow it’s him from HL1! What do I do now?
- Listen to him and create a stack of boxes and climb out of the window.
1.4: This guard is making me pick up his mess. Now what?
- Run away and have him chase you or…pick it up and have him snicker at you.
1.5: City 17 is scary. Where do I go now?
- The right side alleyway.
1.6: Now what?
- Find the right side alley with a ladder and climb up it. Then jump from
the other side. You’re over the fence.
1.7: Ok and?
- Follow the path and find the open apartment building.
1.8: Where do I go now?
- Third floor. Then go across the building and go to floor 4. A group of
people should invite you in.
1.9: Looks like they are in trouble. Now what?
- Exit the window and climb the rooftops. Don’t fall. Enter the building
and go down the stairs.
1.10: I’m so screwed. No way out.
-Enter stage right: Alyx Vance.
“A Red Letter Day”
Length: Short
Fun Factor: 5
2.1: Ok so what am I supposed to do in this lab?
- Listen to Barney and Dr. Kleiner and Alyx and follow what they say.
2.2: Why am I outside instead of with Eli Vance?
- Good Job Hedy Lamarr. I’d have shot the thing if I could.
2.3: Now that Dr. Breen knows I’m around, what do I do?
- Run toward the Train tracks and avoid enemy fire.
“Route Kanal”
Length: Medium
Fun Factor = 4
3.1: Where do I go now?
- Downstairs?
3.2: What do I do about the couple being attacked by combine?
- Kill the Combine. That should Score you a pistol and some ammo. When
you leave, you should be ambushed by a combine that is waiting on the
stairs. Kill him and then go downstairs.
3.3: The path has no ladder! What should I do?
- Wait for the train to come. Then reclimb the stairs and jump on top
of the train.
3.4: OK so now what?
- Crowbar the wooden planks, walk through the building, take a right,
and then follow your way to a bent grate. Jump over it and then take
the right and crawl underneath the hole at the floor.
3.5: OK I'm past the barrier.
- Keep going and drop down into the train pit. Then fight your way up
the stair case and make sure you utilize the flammable barrels. Then
work your way around and then then take the exit and fall into the river
stream. Beware. A train might run into you. :D
3.6: Down the river, eh? I feel like a tadpole.
-Ah poor baby. Keep going til you climb on top of the car. Then fall through
the hole up top. The vortigan will give you a jolt and the man will open
the car for you. Break the wall of wood and crawl under the truck carrier.
Also, avoid the barnacle. He makes his appearance by devouring a bird.
3.7: The couple just got shot to death. Am I next?
- Maybe. OR maybe not. Once you hang right, avoid the plasma mounted gun
guy and hit the tunnel to your right. Take it up and kill all resistance
as you go. Then, climb the inside ladder and take out the gunners.
Don't waste your time, though or you'll encounter resistance and
a few flash happy scanners.
3.8: It's just me and an endless barrage of combine. What do I do?
- Aim for the barrel up top that scaffold and blow it up. It should
knock down a path for you to cross. Then, keep going and then jump down
off the platform and follow the way forward. Avoid barnacles.
3.9: So where am I headed now?
- Hit the pit and then head toward the left open grate. Enter and climb
up the platform. Then, go into the next pit and fall into the water. Do
your best to avoid the falling flammable barrels that fall from the top.
They should blow open your exit.
3.10: Ok so I've fallen off the platform and now I'm being ambushed by
combine. Yikes!
- So use cover and aim for flammable barrels. That should kill a few
combine at once and open you a way out. Keep heading forward.
You should encounter two barnacles. Kill em. Also, experiment with
the physics engine. That should give you some...explosive...results.
Or incase you don't get what I mean, roll a flammable barrel toward
the barnacles and detonate it when it's close to their mouths.
Lots of dead barnacles. Remember this trick for later.
3.11: Next?
- Follow the path and swim to a ladder, dodging combine fire. Then, climb
it and walk along the planks, and then jump over the fence. Swim to the
plank that will accept you and then run toward the open grate, avoiding fire.
3.12: I can't figure out this see saw puzzle!
- See them bricks? Try stacking em.
3.13: Choppers! Ohes Noes!
- Um avoid them and sprint toward your left, finding cover where you can.
Avoid the barnacle and throw the barrel that's obstructing your path. Enter
the door.
3.14: Remember when I said "remember that trick with the barnacles?"
- Navigate the tunnels and use any flammable barrels against them. If
you can't find any, use a normal barrel and run underneath the preoccupied
one. Both ways out are to the left down the ramps.
3.15: Where to now?
- Follow the path. Avoid gunfire. It's pretty linear. Kill the manhacks
that arrive. Stack barrels to get the goodies upstairs. And then follow
the tunnel and exit.
3.16: OK.
- After heading out of the path, fall into the water with the spinning
windmill and follow it, entering the hole on the wall. The path should be
pretty straight forward toward the large pipe with the staircase next to
it. Climb it and then hop on the pipe. But don't head toward the
sunshine. Instead, head toward the steam, walk the pipeline, and
break the wood and drop down.Taking you outside. Fire on the flammable
barrels and make the combine's lives miserable.
3.17: Why did you skip huge section?
- I don't need to direct you all on a linear path.
I only need to address the problem parts.
3.18: Guess what. I just hit one. I'm in the room with the barrels
and a few manhacks. What now?
- This is a good sticking point. Kill manhacks, climb the ladder.Walk
along the pipes. Walk to the other room. Fall down the pipes and turn the
valve. Then return to the room with the barrels and climb down the ladder.
Enter the open hole and climb up to get some air. Afterwards, go back down
and break the wood planks that obstructs the platforms that you can jump on.
Careful, you can break the wooden platforms easy.
3.19: OK I'm in the canal and combine and manhacks are everywhere.
- Kill all resistance, take the left entrance deep into the sewers.
Climb the ladder and cross the scaffolding, and then, crouch and land all
the way at the end of the walk. This should lead you near the end of the
stage.
3.20: Now what?
- Follow the path. Find the rebels. Continue to follow the road and
kill headcrabs and zombies. It should be pretty straightforward, the
road to the hovercraft.
3.21: I'm lost... (god knows how), how do I exit with the hovercraft?
- Well, find the main gate, get out of the craft, and open it.
“Water Hazard”
Length: Medium-Long
Fun Factor = 5
[Warning. I will not walk you step by step through this from here on out.
I plan to address specific sticking points since the game is very linear.]
4.1: Hmm...blue barrels.  Lowered ramp. What do I do?
- Find all five barrels. 2 are upstairs, one is already loaded, and 2
are at the bottom. Plant all five underneath the exterior ramp that's
closest toward your goal. This should lower the other side and make a
jump possible.
4.2: Combine soldiers!
- If you can run them over, do so. If you can run into the planks,do
so. If you see a ramp, the game wants you to jump it.
4.3: Closed gate!
- Park near the ladder and climb it. Enter the building. Kill all
resistance. When you encounter the gunner, grab a barrel and charge
into him, holding the barrel in front of you. This should shield you
from gunfire til you get there. Afterwards, open fire on him and the
three men waiting for you inside. Once there try to activate the switch.
Wait you can't. It's broken. Shoot the flammable barrels and then that
should easily send a plank that slams into the gate opening it. Once
done, escape the building, killing all resistance, and return to your
craft.
4.4: Got some advice?
- Yeah. If you don't have to stop, don't. If the mortars are shooting
at you, try to slalom. Also, when you get to a place where it looks like
there's an exit straight ahead, don't take it. Cut a right and then ramp
up o your right, avoiding the flames. Also, ram weak wooden planks
for an exit and avoid barnacles.
4.5: Another closed gate!
- Drive toward the center of the opening toward the left and exit the
boat. Shoot off the lock and then enter. Grab the Magnum and work
your way around into the warehouse. Avoid the chopper firing and climb
the catwalk. Jump across the ground cars toward the other side. Do I
have to mention the words Kill all resistance? Afterwards, avoid the
chooper again and work your way around the truck cars toward the ladder.
climb it and turn off the gate. USe the cannon gun and then shoot the
chopper down. Climb down the ladder and then return to your ship.
You can jump a few fences or you can take the long way. Exit and then
leave the gate.
4.6: Those pesky choppers!
- Cut a quick right and then do your best to avoid the bombs the
chopper drops. When you come to a section where there's pipes that
are empty, enter them and then follow them. Near the end of this path,
you should see the pipes go into the ground. So instead of going through
them, you should try to keep a good balance and skate on top of it,
sliding into the exit hole.
4.7: The chopper is back. Yikes.
- Again, avoid the bombs it drops. Try to dodge it's firepower, and
when you can. Later on during the track, you should come to a part with
4 barnacles and a path that is all the way on the right wall. Take the
path and then ride your craft over the path, trying to stay as center
bound as possible. This should get you over the way and toward the gate.
Watch out for mortar tanks and the chopper and you should make it to the
exit hole just fine.
4.8: Another puzzle.:
- Park your craft near the ramp and get out of it. Find the ladder on
the left hand side of the entrance and climb it. Walk your way to
the washer machine and push it straight. Then climb down and push the
mechanism. This is a weight distribution device that raises a ramp if
a sufficient amount of weight is pushed on it and then activated.
4.9: The vortigan has installed a brand new gun!
- So use it. ^_^ First target should be the pesky chopper. Next, any
combine in your way.
4.10: Barnacles are a little more than just a minor annoyance now.
-  I agree. Try your best avoid them. What with flaming barrels,
mortar shells, loads of combine, and zombies? Also, Just to let you
know, when you hit the ambush, take your craft up the right ramp and
escape it going straight. Then you'll encounter the flying barrels and
the pain in the neck barnacles. Keep moving. When you find a split in
the path with the combine shooting you on you right, go left.
4.11: Two tanks and no obvious way out?
- You could always kill the tanks and then get out of your vehicle,
go to the car, and shoot through the crack at the flaming barrel with
your handgun. OR you could simply avoid the shells, and shoot through
the crack with your hovercraft. OR you could let the mortar shells
shoot the path open for you. Either or, the car opens up and a
ramp based path is opened for you. This is right near the end of the
stage.
4.12: Final battle with the Chopper
- You versus it, eh? Take it down like the rest but do be warned. It
will use nasty attacks when it's close to death like dropping
loads of bombs and rapid firing it's pulse rifle. To your advantage?
You have loads of space to move around in.
4.13: Me and Eli.
- Head toward the main mill and cut to your left, exiting the arena.
You'll see the exit is closed. Climb the ladder and then open it.
Hop the ramp and deal with the last few Combines. Walk around
and head toward the Observatory. Then activate the switch,
return to the arena, find the now open turbine hole, and hop the ramp.

5.1: Where do I go?
- Around the back. The rebels should let you in.
5.2: Nothing's happening.
- Look at the picture of Alyx, Eli, and his wife. Also
check the wall. This should help you understand the plot.
5.3: How do I climb the way and meet Alyx?

5.4: Dog wants to play fetch.
- So play fetch. Use primary and secondary to propel and pull.
5.5: Scanners!
- Follow Alyx, then follow Dog.

“Highway 17”
Length: Long
Fun Factor = 5
7.1: Hmm the car is upside down and Antlions are after me.
- Kill anything that tries to kill you and use the gravity gun to
get your car back on its wheels. Then, drive and follow the road. Take
the left that leads up the hill and turbo over the ramp. Follow the
road into the tunnel.
7.2: Ok where is this...barn?

- Take the right side road and head toward the warehouse.
Advise by Gameguru 007:
Before you put your buggy over on the opposite dock, wait and several
combines will come out. Use the crane to pick up some shipping boxes and
drop them on the troops. NOW, you can put the car on the other side and
knock the bridge down. Only, NO TROOPS!!!
7.6: Gee a crane. Whatever could THAT be for?
- Position your buggy by the boat and get out. Sprint toward the
pier landing, killing antlions and combine. Get up, drop a ladder, and
use the crane to move your buggy onto the main warehouse dock. Also
knock down that pesky bridge too. Cross the bridge, kill Combine, open
the warehouse side door. Drive through and then drive through the huge
plate of glass.

- Turn it off. Go to the houses and go down the cliff underneath
the bridge. Trail the bridge and go to the other side and turn off
the force field. Kill all Combine and then return. It's not an easy
job but someone's gotta do it.
7.12: I'm still blocked off.
- There's a path between the train cars. hit it and ends the level.
7.13: Those blue balls are a pain.
- Grav gun em into the sea. Don't let them stick to the car.
“Sandtrap”
Length: Medium-Long
Fun Factor = 6
8.1: Augh no more freaking zombies!
- Kill them if they get too close. Otherwise, grav gun yourself a path
and drive.
8.2: Spooky old house on the side of the road. Should I go there?
-If you like zombies and ammo, SURE!
8.3: Another roadblock.
- Hmm...kill, kill, kill.
8.4: Need two batteries to raise the gate.
- One is in a car out back of the battery shed. The other is on
the dead rebel's bed.
Update: I've been also told that there is a hidden battery
underneath the upside down tub.
Alternate suggestion by yelsewniklac:
In the Highway 17 chapter, there is an alternative method to bypass
the barrier that requires batteries to open.  Simply chunk a car next
to wall with the gravity gun, then make a ramp from sheet metal found
among the rubble.  There are at least four bits of it.  Hit that at
full speed in the buggy and you're over.
