  • 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. Download the trainer archive from the thread's attachments.
    2. Run a fresh scan — the VirusTotal link in each post is your sanity check. Disable real-time AV only if a false positive blocks extraction.
    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.

    MrAntiFun has maintained free PC game trainers since 2015. All tools here are community-contributed, tested, and updated per thread.
