After the earth was nearly destroyed by an all-out global war, much of its land has become a wasted desert. You're one of the few survivors who must defend your settlement from hordes of mutants.
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.
