From Team Jailbreak:
This is a full install of Jailbreak 2004a, a mod for Unreal Tournament 2004. Jailbreak adds a new team gameplay mode to Unreal Tournament 2004. Each time you kill an enemy they are sent to jail, a specific closed portion of the map. Once all the members of the opposing team are in jail, your team scores a point. However, there is a switch that will unlock each jail cell, thus releasing any captive players. The gameplay alternates between fragging enemies, breaking your teammates out of jail, and defending the control switch to make sure your enemies dont escape. The result is fast, frantic, and fun. In this version several bugs have been fixed and the netcode has been reworked to enhance performance.
