Star Marauder is the thinking person's ''asteroids'': an arcade challenge above and beyond blowing up rocks. It's a mobile version of the classic, rare, and much-loved arcade game "Star Castle".

Take your craft behind enemy lines and destroy their bases, one by one. The farther you go, the better defended they get.

Shoot out the shield segments to clear a path to the base. Be careful: when you collapse an entire shield ring, a new one will grow in its place.

But watch out! Avoid the guided smart-bombs: they're slow-moving, but difficult to destroy. And the base will fire its powerful cannon if it gets a clear shot.

Star Marauder works on color and black-and-white devices with any screen dimensions.
