Unlike complex mods that require file injection or Cheat Engine tables that break with every update, MrAntiFun’s trainers are standalone .exe files. You launch the trainer, launch the game, and press hotkeys (like F1, F2, etc.) to toggle cheats on the fly.

While using a trainer enhances the fun for single-player campaigns, there are risks involved.

: Game trainers hook directly into the game's executable memory. If Rockstar releases a launcher update or minor patch, a specific version of the trainer may cause the game to crash. Always ensure your trainer version matches your game version.
