EasyAntiCheat is a program that runs on your computer and checks for known cheats or scripts. Not too different from an anti-virus program. EasyAntiCheat (EAC) is the world’s leading third party (external) anti-cheat program.
All the servers on Challengermode are EAC-protected unless otherwise noted.
