Terrorists: You are holding political hostages in Habana Vieja, awaiting a chopper lift which will arrive to evacuate you immediately after the round ends.
Counter-Terrorists: You have control of the perimeter and must now rescue all of the surviving hostages before the terrorists manage to escape.
