Compatibility & Anti-Cheat
Mary Skelter: Nightmares 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.
