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.
A violent fighting game with 5 different types of armies to battle against, cutting them in half, decapitating them, impaling them on spears and kicking heads at them. Pretty similar to God of War game.
