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.
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.
Your chopper crash-landed at an urban war zone. Use your machine gun to get through the hostile enemy soldiers while moving closer to the extraction point.
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.
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?
