Space Gunner is a shoot 'em up game that allows you to blow up objects. You start off as a turret in the middle of the screen- the object of the game is to destroy the various things that come flying at you; spaceships, missiles, rocks.
Don't think you can just keep on shooting however- you get bonus points for accuracy. Should you get hit by an object, it affects your health- if your health finishes it's game over.
The points you get in each level can be used to buy upgrades- missiles, lasers, mines and even an EMP. As you advance in each level, the amount of enemy spaceships and missiles gets bigger- as does the speed they arrive at.
