GTA: Temple Guardian
For centuries, the world is a quiet place to live, but now monsters have come to plague the land. As the current ruler of the land, it is your job to stop these monsters from entering the city. You need to set some defense to intercept them before they can even come close to the city. You need to put some defense around the temple, so the monster cannot get close. Each kill would earn you gold and you ca use the gold to build some towers to stop the invading force. You need to kill lots of monster to be able to afford more defenses.
