This mod is a server-authoritative anti-cheat designed to block common exploits by making the server the source of truth for player actions. It is highly configurable, allowing hosts to tailor the detections to their server's specific mods and balance.
All detected infractions are logged with player details in the BepInEx\plugins\HardAntiCheat\HardAntiCheat_InfractionLog.txt file for server admin review.
