I couldnt find any cheats for this game, so i did a little trainer for it :) 
It has two options: Unlimited ammo and unlimited health. This trainer is 
known to work with the store final version of the game on Windows ME
and Windows 2000.
I looked into doing a "all weapons" cheat, but the way the game is programmed
makes it very hard (and time consuming). Maybe I'll do it some time i'm
intensely bored :P

Enjoy!

BTW:
I found four ways to die that I had to patch out (explosions, falling from 
heights, being hit and being shot). If there are any others please let me 
know and I'll take them out too :] Also, remember that if you give yourself
unlimited ammo then your enemies will get unlimited ammo too!!

This is version 1.1. The first one i gave out had a little typo in the source
code that made you loose health when you were hit.
