GTA: Hold the Line - Zombie Invasion
When the zombie apocalypse happened only few was prepared, so much of the population were erased. The government send some men over, but sadly you are the only one who was left on that batch. The reinforcement will come, but you need to hold them back till that time. The game is played with a mouse and you need to hold the line till the reinforcement. Even the supplies won't be available till then, but the good news is that there is a contractor to which you can buy some supplies. Zombie kills would make you money and you can buy supplies with the money.
