GTA: Alien Anarchy
On a distant planet, your crew crash landed and the ship was heavily damage. To make it simple, it needs some serious repair before the crew can come home. Meanwhile, they were heavily attack by the inhabitants. Did I mention that the crew were aliens and the planet they land upon is called Earth? In this game, you are among the crews and you need to defend your ship from attackers. You would earn some resources and you can use it to upgrade your ship or repair it. The game would be harder and more difficult than before as you make some progress. Try to upgrade your defense to make a better defense.
