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.


This is Pixeljam's first game, originally released in 2006.  We have made a few updates, like 8-way firing, fullscreen and controller support.

It's free because the original was free.  We hope you enjoy it!

A wonderful little game. At some point it got hard.

Good game.

This is a good game !! also i love the 8 bit music. You guys should download it!! It just feels like you're playing in an arcade. Yeah!

So guys, if you're finding a game to play when you're bored, i think you should play this!

A bit of a silly story (commuting to and from work? seriously?)  but a nicely-polished game made even better with controller support!

Kudos to the devs and much love!  Thanks for bringing this to the itchio community!

Is it really a bit of a silly story? Yeah, OK, I suppose it is, but let's be honest, it makes a nice change from defending the world from the nasty space invaders!

I'll download this when I get home... it looks like fun!

What's even sillier is you responded to my comment made ~2 months ago.  There are many ways to have an interesting story without delving into tropes.  That said, while the 'space commute battle' thing is different, that doesn't really mean that it is better.
Might as well not have a story at all and just say 'aliens are there, go kill em' and just give the player that objective like an old school arcade game.

Very gud


absolute classic!
