Gamma Bros
Guide the Gamma Brothers through waves of alien attacks, blasting your way home from work in this frantic twin-stick space shooter about brotherly love. The Gamma Brothers spend their days working hard aboard a massive space station near Jupiter. What are they building? Something very important, probably. The Gamma Brothers also understand the importance of not working. Every day at quitting time they hop into their commuter vehicles for the long, difficult journey back to earth. Every day on their way home, they are attacked by ships and creatures of unknown origin. Swarms of alien vessels, bizarre creatures, and relentless attacks stand between them and getting home for dinner. Gamma Bros is a fast and frantic arcade experience inspired by classic twin-stick shooters. Blast through waves of enemies and switch between brothers on the fly to keep your run alive! Whether you're chasing high scores, reliving the feel of classic arcade shooters, or just looking for a quick burst of action, Gamma Bros keeps things simple, challenging, and fun. After all, their family is waiting. Feature List: Frantic Twin-Stick Shooting: Take on waves of enemies with fast-paced, arcade-style dual-stick combat.

Just a good eye for composition.” Jay Is Gmes
