Walkthrough

Warning the Following is a walkthrough of Half-Life. Please, DO

NOT READ FROM START TO FINISH. If you do, you'll just ruin the game.

And this is one heck of a game - so try not to spoil it. Enjoy!

Half-life: Walkthrough

Three basic tips can help you get started.

First, even if you are an experienced HEV suit user, you should

avail yourself of the Hazard Course. It teaches you how to use the

suit (the equivalent of armor in other games) to its fullest

advantage, and that special long jump module could save your life.

Second, as Black Mesa deals with a wide variety of "special"

experiments, it is important to remember that many useful items are

stored in the plethora of wooden crates and containers throughout the

lab. Smash 'em all and look inside-but avoid the ones marked

"Explosives" if you know what's good for you.

Third, remember that the guards and scientists are your friends;

they can watch your back, heal you, and even get you out of a sticky

situation. Often, if one dies, you cannot continue. Save early and

often.

Chapter 1: Anomalous Materials

This is mostly cinematics, an intro that sets the mood and is

pretty cool in its own right. Not much to do, though. After the intro

train ride, explore the lab a bit, talk to people, find your (Gordon

Freeman's) locker, the HEV suit, then proceed to the test chamber. In

the test chamber listen to your instructions, and follow them to the

letter. Then watch as all hell breaks loose….

Chapter 2: Unforeseen Consequences

Now you're into the game proper. Use the sputtering retinal scan

device to get the door to open slightly. As you make your way out

don't miss the crowbar on the floor (you will need it). You will need

to have a scientist follow you to activate the next retinal scanner.

In the main lobby go through the hole (smash the vent) to enter the

next room. Proceed to the area with the hound-eye beasts (they look

like Smithfield hams with legs). Find a square vent hole leading

downwards (to save health, kill the zombie on the other side of the

bars first). Enter the sewer, find the other square hole vent (in the

ceiling this time) and the valve. Turn the valve, which floods the

tunnel, swim up through that second hole.

On the descending platform dodge the falling head crabs by moving

side to side. Later use ledges to avoid the falling floor pipes. And

you can use the crates to make a bridge in the water, or just swim

around until you can ascend on the other side.

Chapter 3: Office Complex

Avoid the dangling live wire and use the vent to enter the room

with the scientists (watch out for the 'fisher-tongue' critters on the

ceiling). There is an electrical room, and you can shut off the power

there. Exit through the door and now you can safely bypass the live

wire.

When you find the guard in the little control room, try and save

him by killing the zombie who attacks him. Do it fast enough, and

he'll survive to let you in, where you can pick up a shotgun, some

ammo, and other nifty toys.

In the flooded room turn the power off with the light-switch,

making the water safe to navigate. Open the vent and exit the room,

but beware of the fan blade in the vent shaft (duck to proceed).

Guards make good diversions for the annoying head crabs and

security guns you'll find on the stairs. Proceed to the freezer….

Hit the red switch at the far end, and use the ladder to enter

the duct system. Jump onto the moving platform from the upper levels

of the shelves, and move on through the vent.

The elevator is out. Make a running jump and push 'up' to grab

and climb the ladder. Continue moving around the shaft climbing

ladders until you reach the top of the elevator, and break the vent

with the crowbar to drop down.

Chapter 4: We've got Hostiles

Jump or duck to avoid the red or blue trip lasers (red activates

sentry guns, and blue sets off nasty explosions).

Fight the soldiers, but if aliens are around, let them kill each

other. Beware flanking tactics and grenades from the soldiers (they

are very smart). Continue on until you can take the elevator to the

surface.

An Osprey drops guards on the surface to massacre you. Kill all

on the ground and make for the bunker (if you wait, the plane airdrops

more, and more…). Don't hesitate, explosions are constantly rocking

the ground and will eventually get you if you dally.

In the vent system avoid the fan, kill the soldiers, and use the

middle vent (the other two go nowhere) and find a computer panel;

activate it to exit.

Chapter 5: Blast Pit

Find the train/tram, jump on it and hit 'use' to activate it

(forward makes it go faster). Best of all it runs down a lot of the

monsters in the tunnel. Note: at full speed the train will break

through the barrier and send you flying (not necessarily a bad thing

as you can still continue providing you can afford the health), use

the boxes to climb past the slime to the pipe.

Continue on and see what is happening at the Test Fire Chamber.

Its not a pretty sight, but that horrible monster needs to be killed…

how convenient that it is sitting under a rocket engine. To fire the

engine and kill the critter, you must provide oxygen, power, and fuel.

To do this you must get past the tentacles….

You have two choices: you can walk and crouch past and descend to

the various hallways that lead to the controls rooms, or you can use

grenades or shotgun blasts to cause the tentacles to retreat briefly

(then you run for it, repeating the blast at every platform). When

going after the oxygen, fuel and power switches, remember: the order

is not important.

Oxygen & Fuel switches: Go down to the level directly below you,

and break the boards with your crowbar to exit the chamber. Cross the

bridge (hint: don't shoot at the alien on the bridge, those boxes

explode and will make you have to jump across) and follow the red and

blue pipes down the hallway. Break the sewer grate and drop into the

pipes, follow the pipe and turn left, then climb up.

Approach the huge fan and before pushing the button you'd better

save the game (this is dangerous). Hit the button and run up the

ladder hopefully avoiding the fan blades now in motion. Once the fan

hits full speed jump toward it and ride the air current up to the

boarded up ceiling (use your crowbar to break them). Use the vent to

get to the Oxygen/Fuel control room and activate both. Exit by using

the ladder and head back for the test chamber and the giant tentacle

monster.

Power switch: Descend to the lowest level, avoiding the tentacles

as you did before (explosives or skulking). The walkways have huge

holes in them and these jumps are tough, save first. It helps to look

downward to time the jump better.

Once across you will see a huge puddle of water on the floor

(this will become electrified soon, so you might want to arrange the

boxes to form a bridge now) move across it and enter the room. Avoid

or kill the fisher/tongue creatures that hang from the ceiling and

activate the elevator with the button.

Look to your right when it arrives; see that ladder? As the lift

descends, but before it breaks and falls, make a flying leap for that

ladder. Descend the ladder to the radioactive goo and piping. Walk on

the pipes to avoid damage. Find the generator room and activate both

switches (do not do this while on top of it though, or you'll become

all dead and crispy). Watch the spinning platform to get the timing

right and exit the generator room safely. Climb the ladder again, and

look for a platform to jump to.

Once you reach that puddle again you will either have it easy

(you made a box bridge before hand) or hard (you didn't); the

electrified pool is extremely damaging. If you have set up the boxes,

cross using them. If not you can move two crates to form a bridge most

of the way, but it will still cost you around 20 health to make it

across.

Now that the oxygen, fuel, and power are on, you can make some

fried calamari by ascending to the top and hitting the now active test

fire button. Watch the tentacles go boom (you won't take damage if you

back away as far as you can go away from the window, but you'll miss a

pretty explosion).

Exit through the hole once occupied by the tentacle monster. Fall

through the center or you will die by hitting the slanted ground

first. Grab the .357 magnum at the bottom of the pool. Swim around

until you find a broken pipe to swim through, walk on the pipes until

you reach one suspended by cables.

Look across and see a very hard jump to an opening with a broken

grate. Make the jump and beware, the pipe ahead will break (note the

wall discoloration); if you fall with the pipe you will perish, so

jump back as it falls. Use the small ledges on the sides to make a

controlled descent into the room. Kill the head crab under the table

and collect the power-ups.

CHAPTER 6: Power Up

Through the tunnel you come upon an open area where there is a

massive firefight going on. A gargantuan armored alien beast is making

short work of a handful of the government's best and bravest. They

don't deserve your help; after all, haven't they been trying their

best to perforate your geeky skin? Make a break for the open

passageway (across from you, behind the beast) as soon as you can.

Waiting for the soldiers to die just makes the beastie gun for you

(not good).

When you reach the red doors, find the valve-wheel, turn it until

the doors open and climb up through the opening. Follow the signs to

the Power Generator (signs mark the route). Shoot the trip mines below

you, or simply send a detpack (those explosives you may have found)

down the elevator without you.

After the elevator take the stairs down to the bottom, enter the

flooded room (watch out, those fish-things pack a tiny bite, but you

can kill them with your crowbar) and destroy the boxes obstructing the

generator. Climb up one level of those stairs to turn on the fan. Then

head back to where the gargantua is waiting (by now all the soldiers

are dead). Rush past the beast and go immediately to your left down

the corridor. Find the switch, and then head back to the corridor you

that you just came from.

You need to find the track control room. You'll find it by going

up and leaping across the hole. There is a wounded guard there who'll

talk with you a while — if you like. Turn on the power and the beast

will eventually walk into the electric stream and die. Or, before you

do any of this you will find that monster killable if you use

explosives. Grenades, detpacks, — whatever you got so long as it goes

boom. Frankly, though, it's not worth the ammo. Fry him.

Ride the train to the middle of the room, go back to the track

control room and use the switch to turn the train to the other track.

Then ride the train through the boxes.

Chapter 7: On a Rail

Tips for the enormous train areas:

Shoot the arrow-signs to switch the track. Stop the train

whenever you find an area with monsters, doors, or ladders. It is much

more dangerous to go through this area without the train (but it can

be done) as the water and train rail are electrified. Look for

switches, boxes, sentry guns, and monsters. If you seem to be going in

circles on the train find an arrow sign to shoot so you switch tracks.

When you come upon soldiers using mounted rocket launchers get

off the train, crouch, and use your big weapons to fry them. The

rockets pass harmlessly overhead if you are crouched (the train can

protect you from these as well, simply crouch and speed by them, but

you will sometimes miss power-ups).

Finally, after much rail travel, you will come upon a nasty

situation. A huge bunker with a cannon in it, a machine gun nest on

the left, and an open area with lots of soldiers around the corner.

Use a grenade to take out the machine gunner, and hide behind the

boxes to avoid cannon-fire. You can push the boxes ahead of you to get

in closer to the bunker. If you are lucky you can run past the bunker,

into the corridor, guns a'blazing and hope to take out the soldiers

fast enough. But you can buy yourself a little time to snipe if you

take out that cannon. Rush it, climb atop it, and drop a grenade or

detpack into it is one way. Or throw grenades at the top and hope you

get lucky by killing the gunner.

Now you come upon a staircase, with lots of red-laser trip mines.

Since there are no sentry guns you may figure you can jump these

safely. You thought wrong. See the explosives lining the walls? What

you need to do is push the boxes under the second laser, run back and

up the stairs, moving under the first laser (crouch). Then jump onto

the box, then over the last laser and to the door. Watch out for a

couple of soldiers nearby.

Move along until you find the launch controls. Launch the rocket,

and stay at the window for the show! Remember you have to exit the way

you came, which means avoiding the trip mine staircase!

Chapter 8: Apprehension

Get on the train and start her up, you are in for a hell of a

ride. You get the opportunity to get off the train before it crashes,

and you can do that, but you can also ride it all the way down the

hole into the drink. Swim to the bottom of the pool and release the

crates down there, when they float to the surface you can use them as

a bridge to get to the other side corridor.

Lots of swimming, lots of searching, but soon enough you'll enter

a large room with a pool and a suspended cage. Climb up to the top of

the cage and grab the crossbow before descending into it. Use the

switch to drop the cage into the drink. Kill the LARGE fish monster

with the crossbow (the 9mm pistol also works —none of your other

weapons work underwater… except the trip mines, which make for a

satisfying, but difficult, kill).

If you are fast you can skip the fish, but it is much easier to

open the grate and leave the room by killing it first.

When you reach the large control room with the three huge pistons

you have to turn them on, and then jump from one to the other to reach

the suspended catwalk. Kill all the monsters and then the scientist

will let you into the room. He tells you there isn't anything but

danger in the cold room (believe him) and run like mad through it (the

cold does damage) until you find the ladder that leads out.

After the nice guard gets assassinated mid-sentence you will have

to face one of the greatest enemies a 3D action game has given us. The

leather clad sniper/assassin girls. These quick moving targets are

best dispatched with the crossbow from afar (use zoom mode) or by

relentlessly chasing them through the room with the machine gun or

shotgun blazing. Once they are all killed (there are three), you can

move up the catwalk to the platform and use the wheel to open the

door.

There appears to be no way to avoid what happens next. Gordon

gets captured by two sadistic guards who figure its better to kill him

and hide the body than deal with the paperwork. So they place you in a

Batman TV series (the Adam West 60's version) deathtrap, and then they

don't wait around to see if it works.

No weapons, but you still have your HEV suit and the walls start

closing in on you. Carefully but quickly, climb the crates to the

ledge, wait until the walls close and use them as a bridge to the

other side. Grab the crowbar and break open the grate to leave the

room.

Chapter 9: Residue Processing

Lots of traps, noxious gasses, radioactive mess, and danger in

this sprawling jump-fest of a level…

BASIC TIPS:

Save often, jump carefully, and time your movements through

moving machinery well.

When you reach the large vats use the plungers to make it to the

other side. Duck under the grinding wheels. Upon reaching the control

room note the conveyer belts and the massive pounders, move all three

switches to the up position and go and press the green button. Don't

dally, they pounders don't stop for long, run up either conveyer.

Jump from conveyer belt to conveyer belt until you see two

conveyers side by side, get to the one of your left. To get rid of the

nasty trip mine around the corner you want to drop a detpack on the

belt, wait around five seconds, and detonate (be sure to backpedal to

avoid the blast).

Chapter 10: Questionable Ethics

Shoot the electrode switch on the fence to open the door. Once

inside note the terrifying monster behind the glass, take a deep

breath, then break the glass over the switch, and press the button.

Fight the monster with whatever weapon you wish but note the armored

areas, only fire into areas that give you that yellow-green blood

reward.

Run around and try to let the monsters fight the soldiers for

you, once the battle is over pick off the survivors. Find four rooms

with switches and turn on all the lasers. Then find the room with the

sign that says "Do Not Obstruct Laser Shield". Move the box underneath

the laser and then press the button, which lowers the shield and the

box obstructs it from blocking the beam. The beam burns through the

wall and you have your way out… but be sure to pick up the funky gun

from the scientists in one of the other laser rooms before you leave.

Chapter 11: Surface Tension

A situation like this isn't pretty. You have a dam in front of

you, with a bunker shooting bazooka rounds, a long drop off to one

side, and a pool of water with a vicious monster fish on the other…

oh, and don't forget the lethal attack helicopter circling above. You

can destroy the chopper but it is extremely difficult and not really

worth the effort. Head immediately into the water, and up the ladder

to the tower on the far side. Try and keep the tower between you and

the chopper, also beware the snipers on the dam; head inside and pull

the switch. Jump back into the water and kill the fish, or avoid it.

Make for the wall of the dam and find the red wheel. Turn it and swim

through the open grate.

In the next clearing you'll find another seemingly bad situation,

a familiar looking tentacle monster guards some ammo and power-ups

(again a grenade will buy you time to grab it, but it isn't

necessary), the attack chopper is still tracking you, and these odd

bulges in the ground keep sending head crabs your way. Best to head

over to the small hole to the right. Watch out… there is a mine field

beyond.

Use grenades or your machine gun to detonate the mines before

proceeding. Continue on until you find a red wheel to turn and then

head back to the now open grate. Be careful, this fall will kill you…

use the ladder to descend.

This next area, an open area of pipes, canals, and sand bunkers,

displays Half-Life's brilliant soldier AI perfectly — much to your

chagrin. The best way to handle this situation is to climb up the

ladder, pop up fast like a gofer, use the crossbow or .357 magnum to

quickly dispatch nearby soldiers, and pop back down fast. Move

quickly, as the soldiers will soon begin sending grenades down all

nearby holes. Repeat this process with as many of the pipe tunnels as

possible. As far as the tank is concerned — the laser guided missile

launcher is recommended, as is jumping on it and dropping a couple

detpacks. Strafe and try to use grenades or missiles to destroy the

next armored vehicle, which while somewhat lighter than the tank is no

less deadly.

In this area proceed cautiously. Avoid trip mines and land mines,

and watch out for snipers (two of them) in the windows (a rocket or

grenade works wonders here). Blow up the barrels to knock out the

power and crawl under the barbed wire to get to the fallen power

lines. Climb to the roof and jump into the hole.

DO NOT SET OFF ANY TRIP MINES IN THE NEXT AREA! Why? Because

there are a couple of nukes in the warehouse and some idiot decided to

trip mine the entire area. Be careful when moving crates as some of

them can pass through, or are connected to, trip mines. The easiest

way to handle this tense situation is to turn your computer off — just

kidding. Find the crate that rests on a simple lift and destroy it.

Push a crate to the stairs and jump over the laser line, enter the

control room carefully and activate the lift (if you didn't destroy

that crate… boom). From the lift at its highest position jump into the

central area and descend to safety.

Around a corner you'll find some big aliens; let the soldiers

take care of them for you. Round the corner and kill any survivors and

strafe to kill the tank. As you continue, watch out for a sniper in

the window as you round the second corner (this sniper can make

continuing impossible if she kills the nearby guard). Go up the stairs

and find the guard. Have him open the locked storage room for you, and

grab the power-ups. Go through the window and leap to the opposing

ledge. Climb up on the roof and drop down to take care of any

opposition. Then climb back up and proceed to the opposite hallway

(use the rafters).

The next clearing features more of those hornet gun armed aliens

and a circling transport regularly dropping troopers. Let them fight

it out while you make a dash for the tunnel. Move through the tunnel

until you reach the alley where you left that guard you needed to open

the locked door. Enter the room, grab some health from the station and

move up the stairs and up to the big cannon. Use the cannon to kill

any soldiers and blast open the big door you can barely see to your

left.

Whew! Use any of the mounted machine guns to clear the waves upon

waves of aliens coming at you and use the 'bounce crater' trampoline

to jump the wall. Break open the grating and beware the insect-things

(called snarks). Kill or avoid them (they self-destruct after around

25 seconds). Enter the shaft, kill the soldiers in the next room, and

use the tank to kill the aliens that appear. Use the mechanic's lift

to exit the room , then use the bounce crater to get to the next area.

Now use the green map to call in airstrikes to get out of here.

Call one on the wall across the moat, the fortress door, and the tower

before you. Climb across the moat on the fallen tower and you are

done.

Chapter 12: Forget about Freeman

No real puzzles here, just a lot of enemies and killing. Have

fun!

As the ceiling and walls come down try to climb up and through

the newly created hallway. Proceed and fight your way through. Hint:

You can avoid the tank by running like mad to the elevator. Watch for

ambushes, sentry guns, and trip mines.

Chapter 13: Lambda Core

After the snipers are dispatched kill all monsters you find. Once

finished the scientist opens the door; grab the big experimental gun

he's been building. Activate each cooling system switch and enter the

water, swim to the reactor and activate both switches. Climb out and

hurry as the reactor begins shooting lightning.

Time it correctly to use the teleporter to get yourself inside

the core and on the rotating platform. Jump across to each door in

turn, then up to the next level of the puzzle. It's challenging but

fairly obvious once you get a good look at it. Once finished open the

door and meet the scientist and the guard, listen to their story and

grab everything they offer you.

Once the process for activating the big teleporter (that allows

you to bring the pain to the alien world) starts, try and kill the

flying aliens as fast as possible… don't let them kill the scientist

opening the 'porter. Once he says go… you'd better hurry.

Chapter 14: Xen

Welcome to Half-Life Super Mario style. Use your super long jump

ability to go from floating platform to floating platform, and don't

fall. If you see a pool of water from now on, stand in it and it will

slowly heal you.

In the big chamber on the center island 'use' each of the strange

mushroom things, then break the webbing imprisoning the floating

lights (butterfly things). They each go to an open mushroom and

activates the teleporter.

Chapter 15: Gonarch's Lair

Head crabs have to come from somewhere right? Ugh, she is a bad

momma. Aim for the egg sack on the bottom of this exceedingly strange

monster. If it releases pupae versions of the head crabs, use the

hornet gun on them. Once Gonarch runs away follow her to the next area

and keep fighting, while trying to stay alive. If low on health try

and get to the hole and drop down to the ledge below, watching for

adult head crabs. In the tunnels down there you'll find some ammo and

a healing pool. Then use the bounce crater to re-enter the fray.

After you do enough damage a third area opens up and you fall

into a pit. Fire at the sack repeatedly until Gonarch drops down with

you. Then hide behind the strange tree things until you eventually

kill her. Note that you can, if careful, avoid being sucked into the

pit until you're good and ready. Toss some grenades and det packs in

on top of old Gonarch to soften 'er up before getting up close and

personal.

Chapter 16: Interloper

Look for a yellow colored area inside the cave, remove the webs

and ride the white tower elevator to the top. More jumping, just like

in Xen, but this time it's much harder. Jump from floating rock to

floating rock until you come within range of those strange winged bird

things - jump on one of them and ride its back to the teleporter.

Use a grenade or walk slowly past another tentacle monster and

proceed to the next teleporter. Once you enter the factory you'll see

why those lightning spewing beasties are called slaves --kill them if

you like, but they won't attack you. The fliers are what you need to

worry about. Take the lifts to the conveyers and enter the one that

doesn't have a blue forcefield. In the next area avoid destroying the

large barrels… they contain hornet toting aliens with a bad attitude.

Enter the red vents to find a large room with spinning cog-like

lifts, ride them all the way up to another teleporter.

Chapter 17: Nihilanth

Welcome to the end boss… watch out, he may look like a big baby,

and he is quite cranky, but he has powers that will annoy the hell out

of you. Avoid the lightening balls he throws, but most of all use the

rock formations as cover when he tosses a green energy ball. These

teleport you to the most annoying mini-levels you'll face.

The idea here is to destroy the three triangles. You have to use

the bounce craters to get high enough to nail the last one and then

start shooting at Nihilanth's big ole head. After enough hits his head

opens up and you need to send a couple detpacks, grenades, or yourself

inside there to destroy his brain. Good luck, you will need it!

Once the big baby is destroyed you are treated to a wonderful

cutscene featuring that suited character you may've seen. He sheds

much light on this affair and gives you a choice of outcomes for the

endgame. I won't reveal these to you, though; after all, you have to

do something for yourself!
