WeMod is always safe and always free because of our community of millions of gamers around the world. We are supported by WeMod Pro subscribers. Check out our reviews on Trustpilot.

How do I use the cheats in Halo 3: The Master Chief Collection?

WeMod will safely display all of the games on your PC. Open a game from the list and simply press play. After the game loads and once you’re in-game, you can start enabling different cheats!

Will this work with my game version?

WeMod uses advanced technology to detect the game version you’re running and will let you know if it’s supported. If it’s not, you will still have the option of giving it a try or requesting an update!

SGTJCH Very hard to get game to launch and have Wemod work. Can you fix this so that when you launch the game from Wemod the game will start with cheat enabled?

CKoppl Worked well on Halo 3 but completely non-functional on Halo 4. I am going to test on other games. I would purchase this but will not pay a monthly subscription
