Click ~ to open console.

Use the following map names with the "/map [map name]" code:
Single player

If you have console on your game press the`~ button to the left of the 1 a black thing with orange letters should come up at the top of your screen. Then you just type in noclip and press enter then you can fly and go through walls

After the accident, when you go to the area where there
is a scientist sitting on the floor and another is comforting
him, enable the /impulse 101 code. When the man that is
sitting down is talking, beat the standing man with your crowbar
until he dies. When the old man is done talking, the dead man
will talk to you.
When you are done with the first part, after all of the destruction
starts, you will be in a room where two scientists let you into
the machine that you put the sample in. If they are dead, then
this trick will work -- it is after the accident, and not before.
Enable the /impulse 101 code and use the eye scanner that
is lop sided, next to the door. Go through when it allows you
to and you should see a scientist giving Barney CPR. Use any weapon,
preferably the crowbar, and hit Barney. He will talk even though
he is dead on the ground.
Kill A Barney or Scientist. If the body does not disappear, crouch
next to it. Press [Use] and the Barney/Scientist should
talk.
Strategy: by Stalker

Get health in a pinch by diving in the nearest water (not toxic waste) and staying under until the O2 warning flashes. Quickly surface, and you'll get 10-15 health.

This is cool! Call up the console by pressing
the ~ button and type any of these. They do all sorts of camera things:

"chase_active 1" - puts the camera on
"Tomb Raider Mode"
"thirdperson" - Puts the camera in a "Third
Person Mode" where the next
2 codes are useful.
"+cammouseactive" - activates "Camera Looking
Around Mode" which can
change your view in
"Third Person Mode"
"-cammouseactive" - deactivates "Camera
Looking Around Mode"
"chase_active 0" - deactivates "Tomb Raider
Mode"
"firstperson" - returns you to "First Person"
mode.
