GTA: Tequila Zombies
You are out having the time of your life outdoors when the zombie apocalypse happened. When you return to civilization, you realize that the world you once knew has changed into the worst. Now, you need to depend upon yourself to survive and with all the zombies everywhere, you would need to fight them to survive. The idea of the game is to survive as long as you can. You would need to get some money to buy some guns, but money isn't easy in this game as you need to pick it up from the fallen zombies.
