Warhammer 40k: Dawn of War
I know a lot of you have been having trouble with the Dawn of War trainers (basically, like the new Space Marine game, the devs don't want to allow cheats in the campaign), but I found a really excellent Cheat Engine script that works well. It has: Unlimited Requisition, Unlimited Energy, God Mode (Buildings and Units), Unlimited Squad and Vehicle Cap.
It is the only working trainer for Dawn of War 1.51 that I have found, and there are equivalent trainers for each Dawn of War expansion pack.
P.S. This Trainer is not mine, I just decided to share it.
