GTA: Boxhead - The Zombie War
Out of nowhere, the zombie begun appearing and started devouring people. The people that they killed become one of them. Soon, the whole place was filled with zombies. You know that there would be less zombies in the forest since there are few people there. But, then again, zombies travel to different places too. When you got to the forest, you found out that the place is filled with zombies. You need to defend yourself. The idea in this game is to stay alive and by no means, you need to eliminate all of the zombies. You would start with a hand gun and the bullets are unlimited. Eventually, you would unlock other powerful guns.
