Cheating-Death (C-D) is an anti-cheat system which includes both a server and client. Unlike HLGuard, which is a server-side only anti-cheat, C-D offers more protection by blocking the cheats themselves before the player joins the server. While in optional mode, players are checked for a running C-D client and will rename the player if they don't have C-D currently installed and running. For optimal protection against cheaters, servers can be configured to only allow players running the C-D client. Unfortunately, the C-D anti-cheat system is incompatible with VAC secured MODs. As of v2.2.0, C-D can work with VAC supported MODs as long as VAC is disabled. Otherwise, C-D will shutdown if VAC is detected.
