GTA: Zombies at the Gate
The world was peaceful and everything seems to be at place. The king is very happy and he would often go out. However, that doesn't last long as the dead began arising. The gates must be fortified. You would need to gather resources to build your gate. You control the king and you need to gather resources and beat those zombies whenever you see them. You need to gather as much resources as you can before you can build the gate and be able to move up towards the sky. There is no hope left in this land.
