GTA: Zombie Demolisher
No one knows where they come from, but they have eaten most of the people in your neighborhood. Now, they are going to eat more people if you are not going to stop them. The game is played with a mouse and the idea here is to bomb the undead with the wrecking ball. These undead won't be exposed, so you need to find a way to get them. There are no timer in this game, so take as much time you need to find a way to figure how it should be done. The game becomes more challenging as you move form one level to another.
