Enter an infected zone called "Romero E5". Don't let zombies spread over the city's borders by assigning soldiers to repair barricades and shooting at incoming infectees.
As the first line of defense, you must bring down everything in front of you to ensure victory. You have been equipped with four guns, including an anti-aircraft gun to assist you in trouble.
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.
