A fleet of huge alien spaceships is heading towards earth and only you, a humble scout ship, can stop them in time. Isn't it fortunate how routine patrols are always around when megalomanic aliens go on the rampage?

Fortunately, (or unfortunately, depending on how good a pilot you are), you decide to do what any empty headed space hero would do, blow them aliens to smithereens! So you zoom along each alien dreadnought and suddenly... you're in a vertically scrolling monochrome shoot em up! As with all blasters these days, there are some bolt on goodies to stick on your ship and great lumpy mother ships to blow away at the end of each level. The scrolling is smooth and the graphics are neat, if not incredibly imaginative, but unfortunately the game itself is incredibly run-of-the-mill. I'm not saying that it's bad, mind, but just that there are better games, in a similar vein, in this price range.
