We currently don't have any Halo 3 trainers, cheats or editors for PC. We previously evaluated this title and a trainer was not possible or the game is multiplayer/online only so it has been marked as RETIRED. If the state of the game changes where we are able to create a trainer it will be listed on our requests page. Cheat Happens does not support or condone the use of cheats in a multiplayer environment and will never create multiplayer based cheats or trainers.
CoSMOS is a free self-service gamehacking tool and memory scanner designed by Cheat Happens. Search and change in-game values, load pre-made scripts and much more. Simple to use even for beginners with plenty of tutorials and videos to get you started.
You may be able to hack Darksiders Genesis yourself using our FREE gamehacking tool CoSMOS while waiting for a trainer to be made.
