Gamma Bros

Gamma Bros puts you in control one of a pair of brothers who are intent on getting in their little spaceships and cleaning the galaxy of wave after wave (after wave) of enemy spacecraft. With a great range of powerups, multiple boss levels and even a shop system (where you can buy both upgrades and health boosts), Gamma Bros is a pretty immersive game for one so simple. The controls are easy to master and very intuitive, with graphics that are stylistic if a little chunky. Either way, the game play is enough to keep you playing for a good while, particularly after you see the range of enemy craft out there to hunt down and destroy.
