Team Fortress 2
Attack/Defend maps play asymmetrically. RED begins with all the points in their control. BLU wins if it captures all of RED's points, but RED wins if the timer runs out before BLU can capture them all. Points may only be captured in a set order (though some maps, such as Gravel Pit and Steel, may make exceptions). RED wins if it prevents BLU from capturing all points before the timer expires. Points captured by BLU are typically locked and cannot be captured again by RED.
