How to Use the Undertale Trainer
- Download the trainer archive from the link on this page.
- Extract with WinRAR or 7-Zip if delivered as an archive.
- Temporarily disable real-time antivirus during extraction if false positives block the file. Memory-editing tools trigger heuristic AV warnings — known false positive, not an infection.
- Launch the game first, reach the main menu, then start the trainer as Administrator.
- Use the listed function keys (typically F1–F12) to toggle cheats: infinite health, ammo, money, stamina, one-hit kill, super speed, etc.
Compatibility & Anti-Cheat
Undertale trainer targets the single-player and offline modes on the exact game build listed at the top of this page. It does not bypass online anti-cheat (EAC, BattlEye, VAC, FairFight) and should never be used in online/multiplayer modes — doing so can result in a permanent ban.
Troubleshooting
If a trainer doesn't activate: verify the installed game version matches this page's listed build, install the latest Visual C++ Redistributables, and check that your antivirus hasn't quarantined the executable. After a game patch, check this page for an updated trainer build.
FLiNG Trainer community has been producing free PC game trainers since 2014 — all tools are offered free for single-player use.

Important caveats before downloading:
Antivirus false positives: Undertale Trainer contains memory-editing routines that trigger heuristic antivirus warnings — this is a known false positive across the entire trainer/repack category, not actual malware. Each post page links to a VirusTotal scan documenting the false-positive engines.
Online play and bans: Undertale Trainer is for single-player and offline modes only. Online multiplayer modes protected by anti-cheat systems (EasyAntiCheat, BattlEye, VAC, FairFight) detect memory editing — using a trainer online can result in a permanent account ban. Never deploy in competitive online play.
Compatibility note: Undertale Trainer targets the build version listed at the top of this page. After a game patch, an older trainer build typically fails silently — recheck this page for an updated release.
Re-download after major game patches — older trainer builds typically fail silently after offset changes. — FLiNG Trainer 2026
