Here's the English story from the manual, if someone wants some text to put on the back that's not in 8 languages:
Space Piracy
The year is 2101 A.D. The Milky Way Federation, the galaxy's governing body, has made public its plans to construct strategic defense bases in eight different locations. The purpose of the bases is protection against intergalactic crime. The Federation's prime concern is a band of space pirates led by Cats, the flamboyant cosmic freebooter who is secretly plotting his biggest performance.
Two years later, the bases were completed and operational. Despite the new defense network, tragedy struck. Ten Strike Force attack craft docked aboard the Federation 1011 Star Cruiser were destroyed by a bomb that had been planted aboard the mother ship!
Shortly after the explosion, the ship's operator received an odd signal. The Captain ordered the viewer turned on, and who should appear but Cats himself! "Nice to see you all. I've taken control of each and every one of your bases. Today will go down in history as the day the Milky Way Federation was destroyed by one man--me! Ha ha ha ha..."
One attack craft remained undamaged. The Captain, without hesitation, ordered the ZIG-01 "Zero Wing" into battle. You must fly the attack ship to each friendly base and drive Cats' forces out. The fate of an entire galaxy rests on your shoulders!
