Mission Objective - Prevent
	Marine Objective : Protect the control rooms
	Alien Objective : Destroy the 3 computers

Incoming Transmission : This is an emergency alert marines, the bugs have caught us completely off guard. Our supply ship just came down on schedule, but somehow it’s completely infested with xenos – our supply ship must have been lost as well. Get your gear and get out into the base, the bugs are swarming in from the launch pad outside. They’re attacking anything and everything they can, but base defenses are at least keeping the underground levels secure. It’s your job to make sure it stays that way. Our security control systems are enclosed in three sheltered rooms separated around the base. When the alarm sounded they sealed up tight so that no human could possibly access them. Unfortunately, we haven’t yet adequately prepared for the xenos. Each of the rooms is cooled by a separate ventilation shaft high above the floor that a xeno can easily break through. Our marines won’t be able to get into those vents, so you’ll have to stop them as best you can from the ground. If the xenos smash all three computers before reinforcements arrive, they’ll have free access to the base’s underground area and we won’t be able to stop them. Prevent them from gaining access at all costs.
