BattlEye was created in 2004 by German developer Bastian Suter as an external third-party anti-cheat tool for
Battlefield Vietnam. According to the official "About" page, support was quickly expanded to
Battlefield 1942 and
Battlefield 2, where the software was adopted by a number of online leagues and server communities. In 2006 BattlEye was integrated directly into the freeware first-person shooter
Warsow and the indie multiplayer game
Soldat, which were the first titles to ship with internal support rather than using BattlEye as a separate tool. The developer later stated that, after the proactive system went fully live in February 2015, cheating in
DayZ had been reduced to a very low level. BattlEye is also part of the standard dedicated server setup for
Bohemia Interactive titles such as the
Arma series and
DayZ. In 2025
Rockstar Games added BattlEye to the PC version of
Grand Theft Auto Online as part of a wider anti-cheat update for the game. == Technology ==
