Take control of a mining station on an outer planet that's crawled with alien bugs. Defend the station by deploying barracks and towers, train new troops, summon powerful aid from heroes, air strikes and more.
Defend your invasion forces from attacking ships while they retake solar systems from a malicious computer virus. Use your special vessel, the Nautilus, to manufacture ships to assist you in the battle.
