- 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

Troubleshooting

Safety notes for the Nightmare of Decay Trainer:
Antivirus false positives: Nightmare of Decay 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: Nightmare of Decay 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: Nightmare of Decay 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
