I’m aware Infinity does not support Multiplayer games but some bits of the game are non multiplayer and there is a virtual “backyard” and the game would be fine with a trainer that gives coins only and would not be patched. It would be patched due if you create a trainer with invincibility or 1 Shot = 1 Kill
