3D Lunar Crabs is a simple defense game in which you will have to shoot down the crabs that approach your base on the Moon. There are a lot of them but they will come gradually and they will approach the base slowly, at least in the beginning.
The crabs will approach faster as you progress with the levels but you will also be able to use power ups in order to make your task easier. These power ups will appear at random times on the field and you will simply have to shoot them in order to acquire them for the gun.
