After the "accident", you will discover a
scientist giving CPR to a security guard. Wait 15 to 20 seconds
to see the outcome, which usually results in the security guard
being revived. He is not useful at this time, but return to him
after getting the crowbar. Kill him with the crowbar so he can
not fire back to get his gun and ammunition.
Soon after this, you will ride an elevator upward. Have the gun
ready. Shoot the monster attacking the security guard; a couple
of shots should do it. This security guard can cover you until
you reach the main entrance area.
One important tactic in the early game is to use your "allies"
to your advantage. When you no longer require the services of
a security guard, kill him and take his ammunition. A scientist
is also useful in drawing enemy attack. Be careful not to harm
an ally when another security guard is present, as he will attack
you. Also be aware that monsters can sense your allies; and even
if you crawl, monsters can hear your allies' walk.
The beginning of the game also has the following glitch. There
is a scientist sitting in front of a damaged instrument panel,
in the area of the first scientist who opened a door for you.
This scientist is invincible. You can shoot or beat him with a
crowbar, and all he will do is whine. This also saturates the
area with a large amount of blood.
Buy a soda from the random soda machines. If you are
impatient, shoot the soda machine.
The Long Jump module can be used for more than moving
between floating platforms. You can get extra height when you
jump into a wall or other object. When you first get dumped in
Gonarch's lair, to your right you may see white "plants"
coming out of the ground. You can use these as stepping stones
to get up on the raised area in the middle. This may not easy,
but if you get up there Gonarch will have trouble hitting you
with any attacks. It is best to use weapons like the crossbow
for this part. You can also use the long jump technique to get
to other places you are not supposed to, and it is useful for
getting past annoying opponents quickly.
Do not waste precious pistol ammo on headcrabs. Use
your crowbar, as it is more useful.
Using the pistol
Use the following trick to save ammo for all guns other
than pistol. Most creatures or persons can be killed with five
or less direct shots of the pistol.
Crabs: 2 shots or 1 crowbar hit
Zombies: 4 shots
Electric Aliens: 3 shots
Trip Bomb: 1 shot
Machinegun on stand: 5 shots
Soldiers: 5 shots
Dogs: 3 shots
Spitters: 4 shots
If you have a guard, get him close enough and he will
take care of almost anything for you. The only time you ever need
to fire is if the creature is close to the guard.
Barney gets cut in half
When you enter the room where the lasers are shooting
out the walls, run through. There should be a Barney (security
officer) on the floor. Watch carefully and you can see the laser
go across and literally cut him in half.
Glitch: Floating doctor in wheelchair
Note: This trick requires a second player. When playing
a Decay game with another player, get to the Rift level. When
the handicapped doctor tells you to follow him and opens the door,
do as he says. He will get in the elevator. Block his path so
he cannot get in the elevator, but the door is open. Next, back
up slightly and let him enter. Get behind him and run forwards
while the other player pushes you from behind. The doctor should
start to go down, and the door has closed on you, but it is still
open. Jump frequently and press [Forward] quickly. If you
jump onto the safety bar where the top of the other door is, he
will get to the bottom of the elevator. If you stand on the bar,
and he gets to the bottom, then he will launch back up and will
float in the air. You cannot kill him with a regular gun from
below. You must shoot him with the bazooka or from above to kill
Glitch: Man in blue
Enable the "Alien mode" code and start a
new game. Go through the hall past the main security room and
go straight instead of right. A short way down that hall is the
man wearing the blue suit. Use your electric attack to break the
window and jump in. If you try to attack the man with the blue
suit, it will not work.
Glitch: Dead guard talks
After the experiment goes awry, go get the crowbar
and come back to the place where the scientist is performing CPR
on the dead guard. If you smack the guard with your crowbar, he
Approach a guard or scientist that tells you information about
something. Use a gun that will kill them in one shot, such as
the caliber pistol or the crossbow. Shoot them just as you approach
them, immediately before they start talking. If done correctly,
the guard or scientist will fall to the ground dead, but will
still tell you what they originally intended to say.
Glitch: Look through dead scientist's eyes
When you walk around, you will at some point encounter
dead scientists, sitting with their back towards a wall. Crouch
and then crawl toward the dead scientist. You will glide through
him. Continue to walk until you reach the wall, then turn around.
You can now see the way the developers have made the skins for
eyes and mouth and everything else. You can actually look through
the scientist eyes.!
Glitch: Partial invincibility
When in decay mode and are playing both people, the
second person is not invincible, even if you enable the "Invincibility"
Glitch: Sniper target
Get to the part in the Surface Tension level where
you are outside the building with all of the tripbombs and missiles
overhead. Kill the aliens dropped by the alien ship. Then, continue
to the right and go through the "alley", then go left
to see a man on the ground. Note: Do not kill any snipers. Continue
straight and over the barbed wire to the left. Go up the fallen
tower and jump over both vent shafts. To the left, you can see
a broken building with a flat surface , Jump to it. On your right
will be a broken wall. Jump and climb up it. Go to the right until
you see a small crack on the roof that you are standing on. Go
down it carefully. Turn on your flashlight and look to your right.
You should see the sniper as a target with a gun.
Glitch: Extra lasers
In the Surface Tension level, when you get to the storm
drain hatch switch go to the tent to your right. Send one or two
grenades behind the green boxes to blow up the Laser Trip Mines.
Then, go back there and you should see a laser with no trip mine
