Tempest

99 Hyperspatial Wireways have long been crucial to man's ability to travel quickly through space. Thus, when aliens invade them, it becomes necessary to fly into and clear them. Tempest is a shooter using wire-frame graphics. Each Wireway is taken on in turn, and has a network of lines guiding the movement paths of both yourself and the aliens. You remain on the outside and keep shooting as the aliens move towards you. Any that reach the outside are fatal to touch, thus limiting your range of movement greatly if 2 or more achieve this. Some aliens move sideways - in dealing with these, plan ahead allowing for the time your shots to take to travel. You have a Super Zapper, which can be used once on each level to wipe out all aliens currently active, but this scores no points.
