The year is unknown, but it is sometime in a grim future. You're a soldier in charge of a computer room holding secret files to your faction. One night, an explosion caused by the rival faction destroys the room, and kills your team. You've survived the explosion, but you now must fight off waves of droids sent by the enemy to prevent them from seizing any equipment that survived. You reported the explosion to HQ, and backup's on its way. Your objective: survive until backup arrives.
