Planet Master Zero

Planet Master Zero is a defense game where you must do everything you can to save your planet in the face of invasion! Astronauts from many planets will try to come and destroy your power plant. Your job is to build structures that will kill the astronauts and eventually upgrade the power plant so it's harder to eliminate. Check out your power meter in the top of the right hand corner. That will determine if you can purchase certain objects. There are structures that will shoot at aircraft, infantry, and upgrades for all. See how long your planet can last in Planet Master Zero.
