Valve Anti-Cheat, abbreviated to VAC, is a proprietary anti-cheat solution developed and maintained by Valve Corporation as a component of the Steam platform. Although predating Steam, VAC has been fully adapted to its network and, since the release of VAC2, has seen considerable success in the constant battle against cheating in online games.
VAC was first released with Counter-Strike 1.4 in 2002, following Valve's decision to forego PunkBuster in preference of a proprietary system. The initial version, VAC1, saw success for a period, but in March or April 2004 updates ran dry as the Valve engineers maintaining it moved on to the production of its successor, VAC2. VAC1 swiftly became all but useless during this period of development, but since its 20 June 2005 launch VAC2 has successfully overseen a precipitous decline in the number of cheating players across all games "protected" by it.
VAC2 theoretically supports all games, and has today been implemented in GoldSrc, Source, and Unreal Engine 2 titles. It is included in the Steam SDK for licensees. |
