The customized map emulates a real-world prison setting, so use your explosives carefully around tight corners and barred areas. The open format also leaves you exposed, so speed is a factor in taking out your opponent. The multiple stairways are perfect for ambushing—and being ambushed—from above.

To increase the challenge, we suggest setting a limited number of lives per player when playing in matches up to four teams. You can also set your teams as Marines vs. terrorists to get the feel of a mission while playing with friends. Try coordinating your skins and using voice chat to make it a true team atmosphere.
