Play as a pilot of gigantic alien mech. Crash and destroy everything around to conquest the earth. Warning: It contains scenes with ultra violence and mass destruction.
Defend the space carrier with a turret by gunning down as many enemy spaceships as possible. Get additional help by sending out carrier fighters of your own.
We're under attack! Man the turret and shoot the creeps that are overwhelming the planet. Help is on the way but it'll take 100 more days. Can you survive till then?
