Intro In 2002 Valve created an Anti-Cheat solution called “Valve Anti-Cheat” aka VAC. The first game they implemented VAC into was Counter-Strike. When VAC was introduced it only operated in User Mode (Still does) meaning it runs entirely in user space 1 and has no kernel component. Below is a list of games that use VAC.. 2 Call of Duty: Modern Warfare 2 Call of Duty: Modern Warfare 3 Counter-Strike (video game) Counter-Strike: Condition Zero Counter-Strike: Source Counter-Strike 2 Day of Defeat Day of Defeat: Source Deathmatch Classic Half-Life 2: Deathmatch Half-Life Deathmatch: Source Ricochet Team Fortress Team Fortress Classic A longer list can be found here 3.
