-GAMMA BROS is now available to all for FREE-

We've released the game from Early Access, and it's now free for everyone to play. This build should be stable, but if you encounter any issues, drop us a note in the forums.

Windows 10 "ANE" bug has been fixed + up/down control stick inversion option added.

If you have Windows 10, and the game wouldn't start because of an Adobe AIR bug, try it now - this should be fixed.

Current version is 1.2.

This also adds the ability to invert the Y axis, for some controllers that had trouble with it.

“Believe it or not, this simple, Robotron-esque space shooter contains one of the most simple, subtle, and clever methods of developing player/character empathy I've ever witnessed.”

“Gamma Bros. is proof you don't need fancy video cards and polygons to make an immersing game. Just a good eye for composition.”

About This Game

The Gamma Brothers spend their days working on a huge space station near Jupiter. No one works harder than the Gamma Brothers. What could they possibly be working on? Something very important, no doubt.

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. Every day, to and from work, they must survive many vicious and clever alien attacks!

It is up to YOU to guide the Gamma Brothers home. Prepare yourself for the ultimate space commute battle! After all, it is dinner time on earth, and the Gamma Brothers' families will not be pleased if you don't get Buzz and Zap home safely.

Gamma Bros is totally FREE. Isn't that nice?
