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.
