GTA: Zombie Hordes
At a cemetery, people were partying. The grave keeper was so furious that he runs amok and start killing people. Each people he killed turns into the undead and fight by his side. The game is played via mouse and the idea here is to create more zombies that would fight by your side. You would earn some money by killing people. You can use the money to buy some upgrades. The game gets harder and harder as you make some progress. You and your zombies can be killed so turn corpses into zombies. You can replenish your life by raising the dead.
