From the publisher's website:

XenoShyft is a game for 1-4 players, with each player controlling one of the Divisions of the NorTec Military: The Science Labs, Med Bay, Armory, Weapon’s Research, Barracks, and Command Center. Each of these divisions represents one part of the overall NorTec Base, and it is your job as commander of these Divisions to protect the base while its field operations are completed. You and your teammates will have to work together to survive the continuous onslaught of powerful alien threats and horrors- the goal of the mission is not to wipe out these threats, it is merely to outlast them! Survive through nine rounds of combat with these horrors and the base will have succeeded in its mission, and you and your allies will have survived to fight another day!
