|HALF LIFE: Guia del joc|
This Prima Fast Track Guide
provides a quick walk-though of the entire single player Half-Life
game. While it provides enough information and strategy to complete the
game, Half-Life: Prima's Official Strategy Guide contains
additional material such as maps, tactics for using each of the weapons
and how to deal with each enemy as well as other hints and tips to help
you not only complete the game, but master it.
As the game starts, you're on a train
bound for the heart of the Black Mesa Federal Research Facility. A
Security Guard approaches. Follow him through two doors. You're inside
the Anomalous Materials Lab of the Black Mesa Federal Research Facility.
Locate the Suit Room. Press the button
on the computer console to lower the glass that guards your Hazardous
Environment Suit. Walk onto your suit. In the locker room, approach the
locker labeled "Freeman". Take the Battery from inside the
locker. Proceed to a checkpoint. Go through the door. Beyond the
checkpoint you'll come to a large elevator. Take it down to a lower
Follow the corridor on the lower level.
You'll pass through another guarded checkpoint and into a room with
three Scientists. Stop and listen to what they have to say. One will
unlock a door. Go through the door and follow another corridor. Then
take the corkscrew-style elevator at the end of the corridor.
Downstairs, go through the door labeled "Test Lab." You'll
find yourself in an antechamber with two more Scientists. After speaking
to you, the Scientists open the door to the Test Lab. Enter the Test
Climb the ladder and press the button
on the computer console on the balcony. Then climb back down and watch
the machinery spin. After a while, a metal cage on one side of the room
slides away to reveal a cart. Push the cart into the machine in the
center of the room. A huge explosion ensues. Back up and watch the
machinery break down.
Go through the half-open door into the
Test Lab's antechamber. There, press the box on the wall. The door
eventually will slide open far enough for you to exit. Walk down the
corridor. Return to the corkscrew elevator and ride up. Upstairs, a
standing Scientist tends to an injured one. Use the standing Scientist
to have him follow you to the door at the end of the hall. He'll unlock
the door. Walk a step or two through the newly opened door. Bolts of
energy from the Test Lab shoot through a window and destroy a door on
the far side of the room. After this happens, cross the room and run
through the destroyed door.
Run through a hallway where a single
Headcrab roams. Ignore the Headcrab. In the next hallway, you encounter
a pair of runaway laser beams. Avoid them as you run to the end, where
you'll find a Crowbar. Use the Crowbar to smash the glass in a jammed
door. Crawl through the opening. Walk through a hallway to the main
elevator shaft. Smash the glass door that leads to the shaft. Enter the
shaft. Descend the red ladder to the bottom of the shaft where you'll
find a Battery in the rubble. Crawl back up the ladder and then up a
second. Exit the shaft.
Outside, a Mawman attacks a Security
Guard. Kill the Mawman with your Crowbar. Take the Security Guard's
Pistol if he doesn't survive. Kill a second Mawman nearby and make your
way back to the locker room. You must kill two more Mawmen along the
way. A new locker has opened in the locker room. Take the Pistol Clips
you find in it. Proceed to the Anomalous Materials Lab entrance.
Crawl through the hole at the base of
the wall. Move slowly to kill a Headcrab that lunges at you and avoid a
falling bank of computer equipment. In the room beyond, kill a second
Headcrab; then leap onto a series of fallen computer towers and go
through a hole in the wall. Proceed through the hallway beyond the hole.
The hall ends in a checkpoint where a dead Security Guard and a Mawman
lie on the floor. Take the Security Guard's Pistol and crawl through the
broken doors of the checkpoint. Kill a pair of Houndeyes that teleport
into the vicinity and explore the area beyond the checkpoint. Kill two
more Houndeyes and look for a door with a yellow triangle beside it. Go
through the door and kill the Headcrab beyond. Equip your Pistol if you
haven't done so already. Then climb the ladder behind the yellow
triangle door. As soon as you climb the ladder, you'll see another
Headcrab and a Mawman. Shoot the explosive tanks behind the Mawman and
drop back down the ladder to avoid the explosion. The blast will kill
Now you're in a small network of
tunnels ankle-deep in water. Explore the tunnels. You'll find two open,
unbarred holes in the ceiling. Locate a valve wheel. Turn the wheel to
flood these corridors with water, and then swim to the hole in the
ceiling. Climb out. Now you're beyond the metal gate. Explore the
hallway. You'll find a large mechanical lift. Throw the lever you find
above the lift; then board the lift as it slowly lowers into new
territory. As you descend, Headcrabs slide down to harass you. Avoid as
many Headcrabs you can, and shoot the one that gets dangerously close.
You can wait until the bottom of the lift to get off, or if you're fast,
you can get off on a raised area that has an extra First Aid Station.
On to the Canal
Kill a Houndeye that materializes
nearby; then go around a bend. A metal bridge lies ahead. Approach the
bridge slowly. A Houndeye suddenly materializes above it, drops, and
breaks off a span. The remaining span is fragile. Run across and leap
from it to the silvery pipes to the right. Walk around the perimeter of
the room on the pipes, jumping when necessary. The pipes lead to a grate
near floor level. Break it and crawl into the exposed ventilation
tunnel. Crawl until you reach another breakable grate beneath you. Break
it and fall through. You're in a short hallway. Pick up a nearby Battery
from the floor, and then break several crates to reveal more Batteries.
Collect them all.
From here you can look out over a
large, partially water-filled canal with a Bullsquid and several
Headcrabs on the ground and Barnacles on the ceiling. Don't jump down,
but do shoot the Bullsquid and any Barnacles you can see from here. Go
through a door labeled Lower Canal. Go down the ladder beyond and enter
the canal area. Shoot all remaining Barnacles in the canal area. Heal
yourself with a First Aid Station in a dark corner, and then dive into
the canal. On one end of the canal you'll find a ladder leading to the
other side. Climb up the ladder, go through a door, and then locate and
proceed through a second door. Travel through the tunnels beyond the
second door, to a large room filled with suspended boxes. Climb up two
ladders and then slowly, carefully, jump across the boxes to the other
side of the room. From the other side of the box-filled room, go through
a short tunnel, up a ladder and through a couple of doors. You'll find
yourself in an area where you can look out over the canal again. Follow
the hallway to an elevator and get inside. Press the button to ascend.
Exit the elevator and shoot the nearby
Headcrab. Note the locked red doors nearby and the hot, sparking wires
blocking the hall. Break a grate near the floor next to the electrical
wires. Crawl into the newly exposed ventilation duct and take a right.
Shoot out another grate and drop into a room filled with vending
machines, Barnacles, and frightened Scientists. Kill the Barnacles and
then go through a door labeled "High Voltage." Flip the lever
beyond the door. Exit this area through the big red doors that had been
locked. You're back in the corridor, near the elevator where you started
the level. Walk down the hall, past the now-dead electrical wires. The
door at the end of the hallway is locked, but you can shoot the large
window beside it and jump through by crouching as you jump. Beyond the
window is a flooded lab, a big pair of locked red doors, a wooden door
leading to a small storage closet, and more corridor. Approach the
wooden door, stand nearby and beat on the door with the Crowbar until a
Mawman breaks down the remainder. Then kill it and take the Pistol Clips
from inside the closet.
Locate a large storage area. You must
break down a wall of boxes to get there. Inside, you'll find a chest
with a Shotgun on it. At the opposite end of the room is a locked metal
fence with a Security Guard behind. A Mawman attacks him as you
approach. Shoot your Pistol at the Mawman as soon as it appears, and the
Security Guard will survive. Then he'll open the gate and let you in.
Behind the gate is an armory packed with useful ammo and a First Aid
Kit. Take everything and return to the storage room. A ladder leads
downstairs. Take it, and in boxes downstairs you'll find another First
Aid Kit and a Battery. Return to the flooded lab. Jump in through the
window, using a crouch-jump, and then hop across tables and countertops
without touching the electrified water on the floor. When you reach the
light switch on the wall, activate it. This turns off the lights, but it
also makes it safe to touch the water. Turn on your flashlight and look
around. You'll find a Battery in a half-open metal filing cabinet.
There's also a ventilation grate on the wall. Break it and get into the
ventilation duct. Save the game and move forward slowly with your
flashlight on. Hold down the Crouch key, even though it may seem
unnecessary. Kill three Headcrabs as you proceed. Eventually the ceiling
gets higher, but there's a deadly spinning fan overhead. If you don't
hold down the Crouch key until you're past the fan, you'll stand up and
When you reach a grate, destroy it and
crawl past. The floor will fall away beneath you, and you'll find
yourself in a new section of the main hallway. Walk down this new
section of hallway and another section of ceiling falls just ahead.
Shoot a pair of Headcrabs that come down with it, and then arrange boxes
on the floor so you can jump up to a ladder in the ceiling. Climb up the
ladder and break the floor grate you find upstairs. Drop down, kill a
Headcrab, and you'll see another grate. Break it, but take care not to
venture too close to it. An Automatic Turret lies in the room beyond.
Save the game. Watch as a Scientist runs into the room beyond the grate
and the Turret guns him down. A Headcrab is the next to get shot. When
the Headcrab is dead, leap into the room below, run toward the Turret
(breaking wooden crates with the Crowbar to clear a path), and crawl
beneath the metal platform the Turret is mounted on. Flip a switch below
the platform to deactivate the Turret. Explore a small storage room
nearby. There you'll find Pistol Clips, Shotgun Shells, and a Battery.
Kill the Headcrabs guarding a stairwell, and climb the stairs.
A Security Guard stands at the top of
the stairs. Have him follow you and provide fire support. Destroy nearby
crates for ammo, and then enter a long hallway. Explore an office left
of the hallway; you'll see a pair of hapless Scientists being dragged
into a ventilation duct by an unseen creature. Take the Battery and
First Aid Kit in this room. Move farther down the hallway cautiously.
Where the hallway broadens, several Alien Grunts attack. Fall back and
gun them down. Explore the area. More Alien Grunts lurk around here, and
you'll find both Pistol ammo and First Aid Stations in various offices.
Watch out for Headcrabs that burst from
the ceiling. Locate a lounge with a couple of plaid sofas and a
bookshelf. Shoot the ceiling above the sign that says "Maintenance
Access" to reveal a ladder. Climb the ladder and slide to the
right. Nearby, an Automatic Turret starts powering up. Quickly locate
the metal fuse box mounted on the wall nearby and flip the lever to
disable the Turret. Also, collect a Shotgun on the floor near the
Turret. Climb down when you're done. At the edge of the cluster of
offices is a broad staircase. Kill the Barnacle at the foot of the
stairs and then go up, prepared to shoot the trio of Headcrabs at the
Administration Level 2
Take the corridor at the top of the
stairs. Destroy the lone Mawman you find here, but avoid the nearby
boxes: one will explode if you damage it. Proceed along the corridor,
killing two Alien Grunts, and go through the red door at the other end.
Have the Security Guard on the other side of the door follow you down a
nearby ramp. Downstairs you'll find a Bullsquid, Shotgun ammo and some
Grenades. Kill the Bullsquid and take the loot. As you try to leave the
area, two Alien Grunts teleport in. Gun them down as soon as they
appear, preferably with the Shotgun. Go back up the ramp. Proceed to an
area with a sunken floor. Down on the floor are several broken tables
and a Mawman. Shoot Mawman and any Headcrabs that drop down from the
ceiling. Do this from upstairs, avoiding the sunken area.
Go down to the sunken area and break
apart the wooden planks nailed over the doorway. Go through the doorway
and down a dark hall. You'll reach an alcove where two Mawmen feast on
dead Scientists. Kill the Mawmen and press a lever next to the nearby
door. The door opens, revealing a huge freezer. Go inside. Explore the
freezer thoroughly, killing the scattered Headcrabs and pair of
Bullsquids inside. Locate a glowing red switch on the wall and throw it.
This starts a big red cart moving back and forth overhead. Return to
where you entered the freezer. Climb a stepladder and break open a
ventilation grate up there.
Crawl into the ventilation tunnel.
Follow the tunnel to where you can see and crawl onto the big moving
cart as it slowly moves past. Get on the cart. Break the crates on the
cart and collect the Batteries. Then crawl off the far end of the cart
into a wall duct. Crawl through the duct, collecting a Battery near a
dead Security Guard. Break another grate to exit the duct; you'll find
yourself in a large, blue ventilation junction. Methodically kill all
the Barnacles there, and then jump up a series of stair-like ducts into
another ventilation shaft.
Inside the new ventilation shaft, take
a left and proceed until you hit another grate. Shoot it and drop out;
you'll find yourself at the foot of yet another broad staircase. Nearby,
a Security Guard crouches over a dead comrade. Shoot the approaching
Mawman, and then have the Security Guard follow you up the stairs. At
the top is a locked door with a small window. Watch the window. The
dark-suited man appears again, but you can't get at him through the
locked door. Proceed down the nearby corridor and watch as a Scientist
leaps through a window to escape a Mawman. Shoot both Mawmen and jump
through the window to collect some ammo.
Walk to the edge of the empty elevator
shaft at the end of the hallway and look up to see a hapless Scientist
clinging to a ledge. Save the game, and then run and jump to catch the
ladder mounted on the far wall of the elevator shaft. Climb to a ledge,
and then climb a second ladder to another ledge and a third ladder. From
the top ledge, jump to a ladder hanging from the elevator car in the
center of the shaft. Climb that ladder and you'll find yourself atop the
elevator car. Break the ventilation grate atop the elevator car and drop
in. Flip on your flashlight and press the elevator button. Prepare for
the next level.
Exit the elevator and take a few steps
forward. Watch the panicked Scientist bang on the window of a guardroom,
and then run headlong into a Laser Mine. Charge up your health and HEV
Suit at a nearby First Aid Station and an HEV Station. Walk down the
corridor. Around a corner, a pair of red laser beams block your path.
Beyond them lies a stockroom filled with crates. Save the game before
crossing the beams. Dash through the beams. As you do so, a
Tripod-Mounted Chaingun starts firing at you. Sidestep as you fire your
Shotgun repeatedly at the Chaingun. Then kill any nearby Headcrabs. A
Combat Rifle lies on the stockroom floor; you may unknowingly have
walked over it and picked it up as you fought the Chaingun. Take the
Combat Rifle and destroy the crates in the room for a few supplies (such
as a Battery). Avoid the explosive crates. A few extra Headcrabs
teleport in as you explore, but they'll pose no threat.
When the stockroom is clear, find a
hall out the other side. Move slowly! A blue-green laser beam blocks
your path. This beam is attached to a Laser Mine, which will explode if
you disturb the beam. Throw a Grenade so it lands squarely under the
laser beam. The Grenade will explode, taking out the Mine in the
process. When the Grenade explodes, a heavy fire door descends
automatically. Dash forward under the fire door before it closes all the
way. Around a corner is a second Laser Mine. You can destroy this one by
lobbing a Grenade at it or by shooting the Mine itself from as far away
as possible. Proceed along the hallway.
A Vortigaunt teleports in up ahead.
Kill it, and any other Vortigaunts that warp into the same place. Use
the First Aid Station on the wall nearby, if necessary. Proceed along
the corridor and down a ramp. At the base of the ramp is a red laser
beam at floor level, with a Tripod-Mounted Chaingun in the room beyond.
Throw a Grenade at the Chaingun before crossing the laser beam. Beyond
the beam lies a crate-filled room. A Vortigaunt teleports in behind you
as you enter; kill it and jump to the top of the pile of crates. From
the top of the crates, you could jump down to the other side
immediately. Before you do, shoot the two Tripod-Mounted Chainguns on
When both Chainguns are gone, equip
your Pistol and drop down to the new area. Several Headcrabs teleport
into the vicinity; shoot them with your Pistol. Walk through the nearby
web of red laser beams. Jump up on a pile of crates, and then down the
other side. Ahead lie a pool of water on the floor and an open elevator
shaft. Save the game before proceeding. The water will cause you to
slide, and falling down the shaft is deadly, so walk onto the water very
slowly. As you move forward you'll see a pair of red laser beams and two
Tripod-Mounted Chainguns. Lob a Grenade so it lands just behind the
first tripod, and then backtrack. The Grenade should take out both
Chainguns so you can cross the red beams. Go through the laser beams.
Ahead you'll see another storage area with some red laser beams, two
Laser Mines on the walls and a red wall-mounted ladder. Throw another
Grenade toward the two Laser Mines, and stand back while they detonate.
When the Mines are gone, explore the
storage room and destroy all remaining boxes to collect ammo. When the
room is clear, climb the red ladder to a platform, and from there climb
a second ladder to the catwalk the dark-suited man stood on. Cross the
catwalk to another platform. Save the game and approach the top of the
stairs, Combat Rifle at the ready. Kill the Grunt you see down there. Go
downstairs and destroy the crates. Avoid the explosive barrels, or
detonate them from a distance. When you're finished, press the button
near the elevator and get inside.
Things Get Rough
At the top, you'll find yourself in a
large storage area. A metal platform looms overhead. Several Grunts wait
here, and you'll do best if you hang back and duck in and out of cover,
firing off a quick Combat Rifle burst whenever they're in your sights.
When the Grunts are dead, destroy the crates in this room for extra
supplies and use the First Aid Station and HEV Station built into the
wall. Climb the stairs to the metal platform. Follow the platform to a
room with Barnacles hanging overhead. Kill the Barnacles with Pistol
fire and proceed. Past the Barnacle area is a T-junction. To the left
are a pair of Laser Mines, and beyond them lie red laser beams and three
Tripod-Mounted Chainguns. Detonate the nearby Mines with Pistol fire
from a safe distance, and then take a right. You'll come to a room with
boxes on the floor, Barnacles overhead and a conveyor belt on the floor.
Kill the Barnacles and get on the conveyor belt. Follow it into the
You'll come out in a room with a First
Aid Station, HEV Station, and a pile of boxes. Jump up on the boxes.
From the top you can locate another conveyor belt high off the ground.
Jump onto the new belt and follow it into the wall. Follow the new belt
to a small room with a Grunt. Kill the Grunt and use a nearby First Aid
Station, if necessary. From this little room, you can look down on a
corridor filled with Laser Mines, Chainguns, and laser beams. Save the
game. Throw a Grenade down there to clear out the nearest Mines, and
with luck, destroy a couple of Chainguns. Then jump down and go through
the fire door that descends automatically.
To the Surface
Get away from the closing fire door and
look down the hallway toward the big open area. Grunts appear at long
range, intent on killing Scientists. Shoot the Grunts whenever they
appear. When you see no more Grunts ahead, advance. Climb a flight of
stairs to a platform, and then climb a second flight of stairs. Follow a
catwalk to a third flight, and climb them. At the top, you can go two
ways: to the right a catwalk leads to a First Aid Station or to the left
a ramp leads down. Use the First Aid Station, if necessary, wary of the
Barnacle above it, and then descend the ramp. The ramp leads across a
bridge with dead Barnacles overhead and onto a catwalk overlooking a new
area. Look over the edge of the catwalk and shoot a pair of Grunts down
there. Break the boxes on the catwalk nearby to collect a Battery, and
then descend the ramp to the main floor. Downstairs, break more boxes
and collect another Battery. Then locate the Surface Access elevator and
press the button to open it. Get inside and press the button to ascend.
Leave the elevator. You're in a small
concrete structure that's missing one wall. Look out through the open
wall and kill several Grunts running toward you. Strafe as you fire, but
don't leave the shelter of your building. When the Grunts are dead, heal
up at a nearby First Aid Station. Turn on your Flashlight and run out
into the open. Locate the sunken concrete bunker and run inside. It's
dark but your Flashlight illuminates a ladder leading down. Crawl down
immediately. Downstairs, the ground still shakes from rocket attacks but
you're safe from the Osprey, temporarily. Charge up your health and HEV
Suit at nearby stations.
Approach a door labeled "Vent
Access." Open it but don't go through it immediately; instead,
stand back as an explosion drops tons of debris down the vent. Go
through the door. You're in a vertical vent that's open at the top. If
you look up you'll see the Osprey hovering overhead and occasionally
dropping Grunts down the vent to attack you. Look down. You'll see
several ledges or platforms. Jump to a lower ledge, and then jump to a
still lower ledge. At the bottom ledge, you can crawl into a wide
ventilation duct. Crawl into the wide ventilation duct and follow it
around a corner.
Proceed down the dark ventilation duct
to a small vertical shaft with a fan near the middle. This shaft has
four exits, including the one you approached through. You want to reach
the bottom exit. Drop to the bottom of the shaft without getting hacked
to bits by the fan. Do this by crouching, and then inching forward and
right until you fall onto a very narrow ledge. Then creep farther to the
right (still crouching) until you fall to the bottom. Crawl into the
ventilation duct at the bottom of the shaft. Follow it. This shaft opens
into yet another vertical shaft.
Approaching the Silo
As the level starts, you face a
barricaded passage. Use your Crowbar to break down the barricades and
boxes. Beyond the barricades are a few Headcrabs. Kill them and look out
over the large loading area. There's a Bullsquid out here you can kill
easily with your Pistol. To the right lies a ramp. Go up the ramp to a
control panel with a lever. Throw the lever to summon a freight
elevator. As you do, a Mawman bursts from a door to your right; kill it.
Enter the room the Mawman came from. This room is packed to bursting
with explosives, so don't fire your weapons. Just take the ammo and
First Aid Kit you find there and get out. Descend a ladder to the
loading area's lowest level. Get on the big freight elevator you just
summoned with the lever, and press a button to descend into darkness.
Downstairs you'll find an abandoned rail tunnel. Several Houndeyes
scamper below you. Shoot any that get too close, and jump onto the rail
cart. Press the Use key to activate the rail cart's control panel, and
then press the Forward key several times to make the rail cart blast
forward at full speed. Press the Use key one final time when you're at
Stand still as the rail cart hurtles
along the tracks. Don't bother shooting the Houndeyes and Bullsquids you
pass; they'll attack but you're moving too fast to hit. Eventually the
cart breaks through a wooden signpost and approaches a bumper. When it
hits the bumper you'll hurtle through the air into a pile of crates in a
shallow green lake of radioactive water. When you hit the water,
immediately run in the same direction you were flying in—toward the
opposite side of the water. As you run, kill a nearby Bullsquid with
your Combat Rifle. To get up on the far shore, you must jump on the two
boxes. Jump on the lower box, and from there to the higher one. On
shore, climb a ladder to the top of a giant pipe. From there, walk onto
a somewhat smaller pipe with a hole in the top. Fall into the hole and
crawl forward in the dark.
When you reach another hole in the
pipe, you'll be tempted to get out immediately. Instead, hop up and down
in the hole to spot a Bullsquid just outside. Shoot the Bullsquid at the
top of your jumps. This way you can put a few rounds into the Bullsquid
every second or two while avoiding return fire. When the Bullsquid's
dead, jump out of the pipe using the jump-and-crouch technique. This
area features several pipes and a pool of radioactive water. Get back
atop the pipe you entered through (if you fell off), and jump from it to
the topmost of the other two pipes in this room. Line yourself up
carefully for the jump, or you'll find it very difficult. Walk along the
new pipe. Shoot a Bullsquid in a nearby toxic pool as you balance on the
pipe, and then leap down to the balcony. Beyond the balcony is a room
with Batteries and First Aid Kits. Collect as many as you can, and then
Entering the Silo
Go through the doorway from the room
with the First Aid Kits and Batteries to a ledge overlooking a lake of
toxic slime. A missile silo lies beyond the lake. Kill a Bullsquid in
the water below. Hop on a pipe that leads out across the water toward
the silo. Before it reaches the silo, however, this pipe nearly
intersects another pipe that leads to a lift. Hop down onto the new pipe
and make your way onto the lift. Watch out for another Bullsquid hiding
in a corner of the toxic lake. Press the button on the lift and ride
Upstairs, walk slowly down a corridor. As it broadens, you'll find a
Bullsquid to your right near a pair of explosive barrels. Kill the
Bullsquid, but stay well away from the barrels if you shoot them. Follow
a catwalk, killing Houndeyes as you progress, to a bridge. Collect a
pair of First Aid Kits near the bridge before crossing.
A single Houndeye is trapped between
barrels of explosives on the bridge. You can either shoot the Houndeye
and blast a hole in the bridge, or simply run past it. Blasting a hole
in the bridge kills the Houndeye, but then you must jump across the
hole. It's your choice; both methods work. Kill a pair of Headcrabs on
the other side of the bridge. Then enter a small room with a security
door and throw a wall switch. The door you entered through closes, and a
new door opens. You've reached the missile silo's inner chambers. Kill
the Mawman on the other side of the door and walk along the hall. Listen
to the dying Scientist on the floor. Then kill a Barnacle on the ceiling
and keep going. Go through another security door to see a Scientist
standing in the missile silo's control room. After a moment, a massive
Tentacle bursts through the glass overlooking the missile chamber and
grabs the Scientist.
