I was looking for cheats and i found the UBI forum for Rainbow Six Vegas, and someone from UBI said that there isn't any cheat for this game.
And all the posts about cheats in the forum were closed.
Weird!!
If it doesn't have cheats, why would it be so much references to words like "GodMode" and "Cheats" and all the other lines in the post made by MDJ2K and in various .ini files in the game???
Sry for the bad english.
maybe its an anti-cheat system which disable anything that runs with the game and includes those words [god mode, etc...]
