Configure your Mech and go to battle! Collect the special diamonds discovered on Mars and bring them back to base. Watch out for evil aliens or better yet, blast them back to where they came from!
Kill the mutant monsters that want to eat you by shooting them down or throwing grenades. Don't forget to upgrade or buy new weapons to get more firepower!
Welcome to alien infested planet! In campaign mode, missions range from offense to defense missions upon which you can build a base to stop the alien horde. Or there is a survival mode with 6 maps, where you destroy wave after wave of incoming aliens.
