0002                            Introduction
-------------------------------------------------------------------------------
===============================================================================
Half-Life: Opposing Force is mainly a mod of Half-Life released by Valve to
continue the story of the original and give us a little something, well there
have been about 15 mods, to hold us over until Half-Life 2 which comes out this
year.  The game is somewhat shorter than the original game but it is still very
entertaining and presents the same gameplay quality and crappy graphics as the
original.  The game follows the story of Half-Life from one of the Marine's
point of view,
Now in this guide I will hold your hand and take through all the necessary
steps and procedures that you will need to pass the entire game.  I wish I had
this when I first started playing this game.
Now if you find anything wrong with the guide, an error, misspelling or
otherwise feel free to contact me about it, I will fix the error and give you
due credit in the guide.  I am also completely open to strategy submissions,
if you have a better way or have a secret that you want to share about the game
then by all means e-mail me and I will most likely put it in the guide, given
that it is sufficently explained.
That's enough chat right?  Okay, let's do this thing.

3.1                             Story
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------
As a soldier sent in to eliminate Gordon Freeman, you are separated from your
base unit and discover a new alien race amidst the chaos. It's quickly revealed
that these highly advanced alien life forms descended upon Earth to pillage
the planet from the Black Mesa facility when Gordon Freeman transported to the
border world of Xen.
Although you were originally sent into Black Mesa to silence Freeman and his
fellow scientists in the facility, you now find yourself stranded and
confused--battling fierce new alien creatures and a variety of other foes in
an effort to save your own life.
But as a military specialist, you are not unarmed. You'll gather a custom
arsenal of new military firearms, experimental weapons and deadly alien
devices.  And, as you explore further areas of Black Mesa, you will encounter
a new variety of human characters to interact with--on both friendly and
unfriendly terms.

3.3                        Difficulty Levels
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------
Easy- Enemies will only take a few hits and don't do a lot of damage.  As the
name indicates, it is quite easy.  For beginning FPS players.
Medium- Enemies are fairly matched for the most part against you.  They deal
out more damage and you deal out less.  They are tougher to kill.  Not too
hard, but a challenge nonetheless.   For the moderate FPS gamer.
Hard- Enemies will deal out a lot of damage, enemies will take more damage
before they die.  Bosses can be quite difficult at times.  Not for beginning
level FPS players.  Assassins now have a cloaking device, which makes killing
them a real pain in the ass.  Also voltiguants now have halved their charge-up
time for their electricity attack.
-------------------------------------------------------------------------------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.4                            Weapons
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------
Pipe Wrench
-----------
The pipe wrench is a more powerful version of the crowbar that you used in
Half-Life. Use the pipe wrench to break through boxes, grates, and whatever
else you feel the need to personally destroy. Use the pipe wrench to take out
the simpler aliens such as headcrabs and regular zombies (until you get a much
faster knife, that is).
First Seen: Welcome to Black Mesa
Desert Eagle .357
-----------------
The Desert Eagle is the cool new sidearm that you get to use throughout
OpForce.  It is very accurate and very powerful. Use the secondary attack
option of a laser-sight to help make those crucial shots. It holds 7 bullets
per clip with 36 max. The Desert Eagle cannot be used underwater.
First Seen: Welcome To Black Mesa
Knife
-----
The knife is a sharp alternative to the pipe wrench. It is just as powerful as
the pipe wrench, if not more so. It is also much faster to use. When holding
down the primary attack button, you are nearly invulnerable to hand-to-hand
attacks.
First Seen: Welcome to Black Mesa
Shotgun
-------
The shotgun is the weapon that you want to be carrying when you are unsure of
the situation you are going to be dealing with. It is powerful and the ammo
isn't very difficult to find. It is not very accurate except at close range,
though.
Use the shotgun when you want to save the ammunition for some of your other
more specialized weapons. The primary attack is a single shot, but the
secondary attack utilizes both barrels of the shotgun, producing a powerful
double-shot. The shotgun carries 8 bullets at a given time with 125 max. It is
not water-resistant.
First Seen: Welcome To Black Mesa
Hand Grenades
-------------
Hand grenades are the standard-issue weapon of choice for clearing out rooms
and tossing around corners. They have 3-5 second detonations (depending on how
quickly you release them) and bounce accordingly off of whatever they hit, even
enemies.
Use hand grenades to clear out rooms, to trigger explosives, and to surprise
your enemies. You can carry 10 hand grenades at any given time. They can be
used underwater as well.
First Seen: Welcome to Black Mesa
9mm Handgun (Glock Pistol)
--------------------------
The 9mm Handgun is not as useful in OpForce as it was in Half-Life. I recommend
using it when ammo is short, when you are dealing with simple enemies like
headcrabs and regular zombies, and when you want to destroy those annoying
little wooden boxes on the metal shelving units. Otherwise, use the Desert
Eagle as your standard sidearm. The 9mm holds 17 bullets +250 max, which it
shares with the 9mm Mp5 Automatic Machine Gun. It can be used underwater.
First Seen: "We Are Pulling Out"
Mp5 Machine Gun (9mm Assault Rifle)
-----------------------------------
The Mp5 is the best machine gun you've got. It is not as powerful as the M-249
SAW, but it is much more accurate and does not produce the kickback the SAW
does. Besides, it comes with a grenade launcher.
The Mp5 is very good for unloading a 50-round clip into some of the more
difficult, lightweight aliens. It holds a 50-round clip internally with 250
bullets max. Ammunition is shared with the 9mm Handgun. 10 AR grenades can be
carried as well. The Mp5 does not work underwater.
First Seen: "We Are Pulling Out"
C4 Satchels
-----------
C4 satchels are the most powerful explosive you carry. When selected and used,
a C4 satchel slides along the floor and waits for you to detonate it via the
remote control that pops up. If you want to add more C4 detpacks to the
trigger, use the secondary attack to drop more satchels. When the handheld
trigger is visible, the primary attack button will detonate all C4 satchels.
C4 satchels work well as standard weapons and as traps. They also float and
detonate underwater, making them very useful for underwater combat. You can
have 5 C4 satchels at any given time.
First Seen: "We Are Pulling Out"
Tripmines
---------
Tripmines are the ultimate in silent traps. Set one on a wall, tempt your enemy
from behind and watch as your enemy unknowningly breaks the tripmine's laser-
beam, triggering the explosive. It is very fun to use tripmines creatively,
outsmarting both NPCs and human players, either in singleplayer or multiplayer.
Tripmines must be attached to some form or structure. They cannot be set in the
air. You can hold 5 tripmines at any time. They are functional underwater.
First Seen: Missing In Action
Rocket-Propelled Grenade Launcher (RPG)
---------------------------------------
The RPG packs a lot of punch. It launches rocket-propelled grenades in one of
two modes. The first is a straight-shot (dumb-fire) where the rocket hits the
initial target no matter where your view shifts. The second is a laser-guided
shot whereby the rocket is guided by a laser that you control until the rocket
detonates. Hence, you can guide rockets around corners, up stairwells, and
towards moving targets. The RPG carries 1 rocket at a time with 5 max. It can
be used underwater.
First Seen: Missing In Action
M-249 SAW Light Machine Gun
---------------------------
The M-249 is the new powerhouse weapon in OpForce. It is very powerful, but at
the expense of accuracy. Use it on larger aliens like shocktroopers and
particularly voltigores. The kickback from the weapon will drive you backwards
and throw off your accuracy, but when something is caught in the M-249's line
of sight, it won't survive very long. The M-249 runs through 50-bullet clips
very quickly at any time and can have 4 clips max (4 * 50 = 200 bullets) in
reserve. The M-249 does not work underwater.
First Seen: Friendly Fire
Displacer
---------
The displacer is a very interesting experimental weapon. Its primary attack
shoots out a glowing orange orb that will do severe damage to anything within
its blast radius. The secondary attack, however, will displace you in space. In
single-player, you will end up displaced to the alien world Xen, where you can
grab some supplies and then return near where you left by nearby portals. In
multi-player, you are merely displaced to some other position in the level.
The displacer takes nuclear battery packs and its "ammo" is really the
percentage of battery power left in the weapon. Primary attacks take 20% of the
battery power and secondary attacks (displacements) take 60%. Gather new
batteries to restore power to the displacer. The displacer can be used
underwater.
First Seen: We Are Not Alone
Shockroach
----------
The shockroach is the standard weapon of shocktroopers. It is basically an
alien unto itself that fires up to 10 bolts of electricity very rapidly. The
shockroach is constantly generating electricity, so there is no need for ammo.
The shockroach may work underwater, but it will kill you if you try.
First Seen: Crush Depth
Snarks
------
Snarks are little aliens that run around and attack any living beings in the
relative vicinity. Use them to clear out rooms and to determine what type of
enemies may be waiting in the next room. Drop a few snarks into a room and
listen for what types of weapons and cries are heard. You should be able to
determine what might be waiting for you around the corner. You can carry 15
snarks at any time. Snarks can be used in water, but as they can float, they
aren't very useful there.
First Seen: Vicarious Reality
Barnacle
--------
The barnacle is one of the coolest weapons you get to use in OpForce. It can be
used as a weapon, which latches onto enemies and drags them into its tooth-
filled mouth. However, the barnacle is especially useful in that it can latch
onto fixed organisms (such as spores and alien moss), effectively dragging you
along as it tries to reel in its catch. Thus you can swing your way into out-of
reach areas and out of harm's way. The barnacle will only latch onto organic
matter, though.
First Seen: Vicarious Reality
Spore Launcher
--------------
The spore launcher is a cool new alien weapon. You gather spores from small
alien lichens that constantly produce them and use them with your new weapon.
The creature that is the spore launcher eats spores and then spits them out
when you give it a squeeze.
The spore launcher has two modes. The primary attack spits out a spore-rocket
relatively straight ahead, whereas the secondary attack tosses out a bouncing
spore-grenade. The spore launcher can have 5 spores in its mouth at one time,
and up to 20 more spores can be carried. The spore launcher can be used
underwater.
First Seen: Vicarious Reality
M-40A1 Sniper Rifle
-------------------
The M-40A1 sniper rifle is the best weapon for long range and precision-made
shots. If you want a dead-aim headshot on your favorite enemy, take out your
sniper rifle, switch to your scope (secondary attack) and line up your sight.
The sniper rifle is very slow at both resetting a shot and reloading a clip. It
uses 5-shot clips with 3 clips (3 * 5 = 15 bullets) carried. It cannot be used
underwater.
Also note that if you load a saved game while the sniper rifle's scope is on,
then it will remain on no matter what weapon you have readied. However, this
can be inconvenient, so either ready the sniper rifle and hit the secondary
fire button a couple of times, or just quit and rerun the entire game.

3.5                            Enemies
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------
Regular Zombies (Hybrids, Mawmen)
---------------------------------
Regular zombies are the slow-moving products of successful headcrabs who have
taken over their host's body. You may remember regular zombies from the
original Half-Life, and you may remember that they aren't too difficult to beat
A few shots to the head and they are down. If they get close enough, they will
slash at you with their powerful claws. Avoid this if possible.
To kill a zombie with the knife or wrench, walk up to him and whack him once
and then back off quickly. If he starts his slow two-arm swing attack, move in
as soon as he swings his second arm and get in two or three good whacks before
retreating. If he uses his faster attack, you should only risk one hit after
it.
First Seen: Welcome to Black Mesa
Headcrabs
---------
Headcrabs are little quadrupedal aliens that lunge at your head. If they were
to succeed in killing you, they would tie into your brain and turn you into a
zombie. Headcrabs are for the most part easy to kill. They mainly walk towards
you and jump at you. Pull out your knife and carve them up before they hit you.
One way to kill headcrabs without using any ammo is to dodge when they leap at
you, then quickly run up to them and whack them with the knife or wrench. They
can't jump backwards or sideways, and it takes them awhile to turn in place and
prepare for another jump.
First Seen: Welcome To Black Mesa
Alien Slaves (Vortigaunts)
--------------------------
You may remember alien slaves from Half-Life. They are relatively fast creature
that discharge a powerful electrical bolt that can quickly cripple whatever it
hits. It takes slaves a few seconds to power up, which gives you a chance to
disable them. Slaves can also fight up close, hand-to-hand. A single shot from
the Desert Eagle will usually down an alien slave with relative ease. Just
avoid the electrical bolts and you should be fine.
A note for Difficult-level players is that the slaves' power-up time is cut in
half, allowing them to fire much faster.
First Seen: Welcome To Black Mesa
Barnacles
---------
Barnacles latch onto the ceilings of buildings and dangle their tongues down
from above. The tongues will grab onto whatever happens to step into them. Once
caught, the tongue is quickly retracted, elevating the victim to the barnacle's
tooth-filled jaws.
You can usually just avoid the tongues if you see them. In OpForce, though, the
developers made specific use of light and dark to help conceal the tongues of
barnacles. Pay close attention to avoid being caught in them. If you are caught
switch to your knife and start slashing at the barnacle immediately, regardless
of how far down you are. You want to hit the barnacle before it hits you.
First Seen: Welcome To Black Mesa
Houndeyes
---------
Houndeyes are the dog-like creatures from Half-Life. They travel in small packs
and produce a shrill sonic burst that can injure their victims. Houndeyes are
very easy to deal with. A shot to the head will kill them immediately. Make
sure to take out the houndeyes that are starting to "scream" before they
unleash their attack on you.
First Seen: Welcome To Black Mesa
Shocktroopers
-------------
Shocktroopers are fast, lightweight, bipedal aliens. They carry shockroaches,
which rapidly fire electrical bolts at you. Don't get caught in the
shockroach's line-of-sight, as the bolts of electricity can quickly kill you.
The shocktroopers also carry spore grenades, which they use when they can't
reach you with the shockroach. Avoid these as well, since they can inflict
severe damage to you.
Shocktroopers are quite smart and fast. They will work in primitive squads and
they are particularly good at investigating peculiar disturbances such as the
death of their squadmate. When you kill a shocktrooper, the shockroach left
behind will attack you until you either kill it or it expires. They usually
expire after five or six seconds.
If you don't have a shockroach as a weapon yet, you will pick up the shockroach
before it can hurt you. Otherwise, it will attack. The first time you see a
shocktrooper is in "We Are Pulling Out," but you don't actually fight one and
gain a shockroach until Crush Depth.
First Seen: "We Are Pulling Out"
Advanced Zombies (Hybrids, Mawmen)
----------------------------------
Advanced zombies are headcrabs that have fully overtaken their hosts' bodies.
Advanced zombies are very powerful; they are a bit faster than regular zombies
and they can now launch acidic globs of mucus at you.
It is better to stay back, avoid the globs of mucus, and plant a few shots in
their foreheads. One or two shots to the head from the Desert Eagle will kill
an advanced zombie. They may be somewhat challenging but they aren't very smart
Use that to your advantage.
First Seen: Missing In Action
Pit-Drones
----------
Pit-drones are small, quick little alien creatures that have two sickle-like
arms that they use to slice through their victims. They can also spit sharp
teeth at you from a distance.
For the most part, pit-drones are simple to deal with. They merely spit from
afar and then run up to you to attack up close. Plug a few shots into them and
they will go down quite easily. Watch out for entire packs of pit-drones,
though. They can swarm on a victim, making things very difficult.
First Seen: Missing In Action
Bullchickens (Bullsquids)
-------------------------
Bullchickens are fairly large, bipedal aliens that will spit green globs of
mucus at their enemies. They will charge at their victims as well. Try to take
out bullchickens from a distance. Their green globs of mucus are quite slow-
moving and you can easily avoid them. Bullchickens will attack any type of
organism, including their own species. Hence, if you find a bullchicken hanging
around some other aliens, let it clear the area for you. (There are some types
of alien they won't ever attack, such as alien slaves.)
First Seen: Missing In Action
Alien Grunts (Xen Soldiers)
---------------------------
Alien grunts are the large, hornet-shooting aliens from Half-Life. They do not
appear very much in OpForce, so deal with the three or so that you meet in any
way you want. They fire heat-seeking hornets at you that chase you down. Grunts
take quite a bit of firepower to put down, but compared to newer aliens such
as the voltigore, they should be pretty easy. Always aim for the head of a
grunt, though. Body armor helps protect them, although the body armor is not
impervious to your weaponry.
First Seen: Friendly Fire
Military Turrets
----------------
These are automated target-seeking machines that the military has set around
for automated defense. They can't walk around, but they can swivel 360 degrees.
They start out dormant, but activate and scan for targets when you (or someone
else) walk through their red laser alarm beam, brush up against them, or start
damaging them.
The best way to take one of these things out is to shoot it in the leg or in
the top of its "head" while keeping something solid between you and it so that
it can't shoot you. Bouncing a grenade around a corner also works well.
First Sighting: Friendly Fire
Assassins
---------
Assassins are particularly worthy enemies. They are fast, agile and smart. They
work in teams and can quickly surround you or flush you out of hiding. Try and s
stay covered but don't be restricted by cover, and concentrate on taking out
assassins one at a time.
There are two types of assassins: female assassins fire silenced handguns and
do a lot of running (you saw these in some places in Half-Life); male assassins
carry heavier machine guns and grenades and they don't do quite as much running
around as the female assassins do.
Never expect to hit assassins up close with a handheld weapon; it just doesn't
work. Instead, pull out your Mp5 or your M-249 and send up an impenetrable wall
of bullets, or set a strategic tripmine or C4 satchel. Be sure to pick up the
ammo left behind by fallen assassins.
First Seen: Friendly Fire
Alien Controllers (Xen Masters)
-------------------------------
Alien controllers are aliens that fly around and toss glowing orange orbs at
their enemies. They are the aliens that you first meet in the Lambda Sector's
gateway to Xen, both in Half-Life and Opposing Force. Avoid the orange orbs
and take aim at their massive skulls. Use the Mp5 to keep a constant wall of
bullets up in the air for them to run into. Otherwise, don't worry too much
about alien controllers. You only run into them during Gordon's infamous jump
into the gateway to Xen.
First Seen: We Are Not Alone
Larvae (Hagworms, Leeches)
--------------------------
Larvae are small little worms that swim around underwater. You usually don't
meet many in OpForce. They are very easy to kill. One swipe from the knife or
the pipe wrench will put an end to their existence. Larvae will swarm on and
eat away at their victim. They do not do much harm even in large swarms. Just
be sure to deal with them before they do any real damage to your health and
PCV battery power.
First Seen: Crush Depth
Ichthyosaurs
------------
Ichthyosaurs are the alien equivalent of sharks. They look, act, and exist like
sharks. You will only find them in water. Ichthyosaurs will pace around the
container they are in and they will usually circle their prey before they
attack.
They will charge and attack their enemies in one swift motion. Their attacks
can easily confuse you, preventing you from recovering quickly. Hence, avoid
direct attacks from ichthyosaurs. It is often better just to swim quickly past
them before they can attack. Few weapons work in water so unless you can fight
them, you might as well just avoid them if possible.

Voltigores
----------
Voltigores are large, quadrupedal animals that are very powerful. They have
sharp points for feet that they use to gore their victims up close. From a
distance, one will generate an electric field that travels towards its victim,
severely crippling it.
It takes a lot of ammunition to take out a voltigore. Use weapons like the
M-249 SAW and the RPG to maximize the damage you inflict on voltigores. Avoid
the purple electric fields that they produce. Also realize that voltigores will
almost always chase you down. Hiding behind a corner doesn't usually work. Baby
voltigores are just like adult-size voltigores, only much easier to kill.

Snarks
------
There is only an isolated incident (at least that I've found) where you have to
deal with snarks. Most people may never even see the live snarks throughout the
entire game. Snarks hunt down and viciously swarm on their victim. They are
quite fast and can jump over barriers and such. Snarks will expire after maybe
ten seconds or so. A shot or two from the Mp5 will kill a snark; it is just a
matter of hitting them.
First Seen: Vicarious Reality
Giant Tentacles
---------------
Giant tentacles are huge, well, tentacles that have a very sharp beak on one
end. Tentacles are unbeatable using conventional weapons. You will usually just
have to avoid tentacles rather than fight them.
Tentacles can only hear noise. They cannot see you. Hence, you can either creep
past them using the walk modifier or you can distract them by tossing grenades
in the opposite direction. Just remember, one hit from their beak will usually
kill you.
