Apparently, you have been deserted in space by your escort whilst test-flying a new starship. Confronted by an Imperial Strike Force, the starship is incapable of out-running the enemy; all that can be done is to stand and fight until your almost inevitable destruction. The imperial mothership is protected by four types of defence fighter. These must all be destroyed before it is possible to attack the mothership herself. To make it more difficult, you are only supplied with three shields and a limited amount of laserbolt energy.
Little can be said about Starclash, except that it is only one step up from Space Invaders. Undebiably, the game is addictive but hardly original. Action is too slow to start, and your laserbolts travel painfully slowly. Action is reasonably smooth, the graphics are quite good, and the sound is about as good as can be expected from the Spectrum. In short, fairly poor.
