You are one of the last survivors of the apocalypse. Zombies and street gangs roam the streets of the city. Both are dangerous. Eliminate zombies and gang members to earn gold to buy more ammo and better guns. Visit the clinics to heal up, or the gun shops where you can hire the owners to help with your battle. As you roam the streets and subways, keep an eye out for the storm, which moves quicker towards the end of the three rounds.
