Jailbreak is a Mulitplayer Teamplay mod for Half-Life.
Jailbreak continues the eternal battle between the reds vs. the blues.
The difference in Jailbreak from other teamplay mods, is that in Jailbreak instead of trying to capture a flag or a goal, your team must capture the entire enemy team. When you have fragged an enemy player they are captured and placed in the jail of your team's base. When all of the enemy players have been captured, then they are executed and your team scores the capture point. But there's a catch. There is a jail release button in your base, if an enemy player infiltrates your base and presses this button, then your jail doors fly open and all of the prisoners are set free.
