CosmoStation Noah in Spiral Galaxy IX is being held captive by a group of intergalactic terrorists known as the Molok Wardrivers. The only hope against this ruthless armada is the station's RH 119 warship, equipped with barrier shields, laser cannons, a life support system, and a bio-computer called Adam. However, only one can take control of this ship. That one person is you.

In Star Voyager, it's you against the Molok Wardrivers in an intergalactic war. In addition to blasting away enemy ships via a first-person perspective, there is also some strategy involved. You must use your map of the galaxy to initiate battles, refuel at other space stations, or visit planets which may give you more powerful resources. Be careful not to visit an asteroid field or black hole, though. Your game will most certainly end, just as it will if you are destroyed by the enemy, you run out of fuel, or the enemy destroys CosmoStation Noah before you can stop them.

The fate of millions of innocent people rests on the shoulders of you, the Star Voyager.
