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.
Do not waste precious pistol ammo on headcrabs. Use
your crowbar, as it is more useful.
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.
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: Partial invincibility
When in decay mode and are playing both people, the
second person is not invincible, even if you enable the "Invincibility"
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
