Here they are!!  The codes for GOD MODE, NO CLIPPING, etc!  They were posted 
on the Internet by some guy.


You just have to type the following magic words while playing:

 iddqd               Degreelessness mode (God mode)
 idkfa               Very Happy Ammo. (full ammo +  200% armour, no backpack)
 idspispopd          No clipping (SPISPOPD?)
 idbehold            followed by S, V, I, R, A, L for various things (menu)
 idclev              followed by episode number and level number: warp
 idmypos             prints your co-ordinates in hex
 idchoppers          prints 'Doesn't suck - GM' (What ??????????)

Have fun!
