Geo Shooters is a Galaxian-type game, but with some new ideas. The enemies move back and forth like the classic Space Invaders, but they shoot directly at your ship. Some drop down and try to hit you, and some come up from behind you. One really nice feature of this game is that your health increases when you stop shooting. This allows you to gain back some health if you are really low on it, but only if you are willing to stop shooting. This is similar to Power Shooter, which you should also check out if you like this game.
