Antivirus False Positive Notice
This trainer uses memory-editing technology to modify game values in real time. Some antivirus programs may flag it as suspicious — this is a known false positive common to all memory-editing software, not an indication of malware.
Verify the file yourself: Upload it to VirusTotal.com to scan with 70+ antivirus engines before running.
How to Install the Under The Island Trainer
- Download the trainer archive from this page (button above).
- Extract with WinRAR or 7-Zip — password if any is shown beside the download.
- Disable real-time antivirus only if a false positive blocks extraction. Trainers modify game memory; many AVs flag this as a generic heuristic. The included VirusTotal scan is your sanity check.
- Launch the game first, reach the main menu, then start the trainer as Administrator.
- Use the listed function keys (F1–F12) to toggle each cheat — health, stamina, money, ammo, instant skill cooldown and so on.
Compatibility & Anti-Cheat
Under The Island trainer targets the single-player and offline modes on the exact game build noted at the top of this page. It is not designed for online or multiplayer play and should never be used with Easy Anti-Cheat, BattlEye, FairFight, or VAC-protected lobbies — running a trainer there can result in a permanent ban from the game's matchmaking servers.
Troubleshooting
If the trainer hotkeys don't activate: confirm the game version above matches your installed copy (Steam → game properties → Updates), install the latest Visual C++ Redistributables, and verify your antivirus hasn't quarantined the executable. After a game update, check this page for an updated trainer build before reporting a problem.
