Jailbreak: Source is a multiplayer team-based first-person action video game, developed as a total conversion modification on the Valve's proprietary Source engine. The game was in beta development stages before it was abandoned, with its first public release on 14 February 2007. 0.2 followed a week later as a patch. The third major public version was released two months later on April 21, 2007. The next release was made available just over a year later, on May 3, 2008 with the latest version (0.6) being released on 15 January 2010.
