Cheat Codes:
set ai_disable 1 Prevents the enemies from moving or attacking
set cg_drawFps 1 Graphical Frames Per Second displayed on-screen
set cg_drawTarget 1 Show information about an enemy or object that
is within your targetting reticle.
This one is neat; it will show you which body
parts you are aiming at, such as Head, Arm.
set cg_drawWeaponStats 1 Display statistics about your weapons fire,
such as the Number of bullets fired, damage
dealt, etc
set developerMenu 1 Enable the Developer Menu items
adds extra options in the Main Menu system and
other menu's. However, the extra options seem
pretty worthless.
set god 1 Enable God Mode
This one is a bit strange.
Attacks from enemies will still damage your
armour, but not your Health stat.
Also, if you or an enemy explodes a Red Box
which is very close to you, it can still
instantly kill you.
It is still useful though; you can stand in the
middle of 6 enemies who are shooting the hell
out of you and not die or lose health.
set physics_disable 1 Disable the laws of Physics
Rather useless, because it prevents both you
and the enemies from moving at all. You can
rotate/pivot around with the mouse. If you
kill an enemy, it will still stay standing up.
set r_debugVis 1 Show Debug Information about meshes and such
set r_debugVisBox 2 Show Debug Boxes (like wireframe) on objects
set showNavForPlayer 1 [unknown]
set wheelSpeeder 1 [unknown]
