  • How to Use a MrAntiFun Game Trainer

    Compatibility: Trainers on this forum target the single-player mode of PC games on the exact version listed in each thread. They do not bypass online anti-cheat systems (Easy Anti-Cheat, BattlEye, VAC) and should never be used in multiplayer or competitive modes.

    Installation (4 steps):

    1. Use the download link in the thread. Check what you receive before running it.
    2. Scan the file yourself before running it. Trainers edit game memory, so antivirus tools often flag them heuristically.
    3. Launch the target game first, reach the main menu, then start the trainer (Run as administrator).
    4. Use the assigned function keys (usually F1–F12) to toggle options: infinite health, stamina, resources, etc.

    If a trainer doesn't activate: confirm the game version matches the "Game Version" header; update Visual C++ Redistributables; and check that your AV hasn't quarantined the executable. Discussion and fixes happen in Trainer Support.

    All tools here are community-contributed, tested, and updated per thread.
