Here you go Stomp...

It's fairly simple to use.
just drop the exe into your c:\Program Files\Ubisoft\Far Cry 2\Bin folder and shortcut it to your destop. open the trainer before opening the game (it will show a full list of each hotkey and their action)... while in the game menu press F1 to activate and then load the story mode.
I always activate F1, F3, F4, and F6. press any of them again to deactivate them. Basically, anything on the number pad hotkeys are pretty much cheats, anything on your F keys are to make the game more enjoyable.
