This is the longest programme ever produced for the ZX Spectrum, it is not an arcade copy and no amount of blurb will adequately describe it - just play it.

You are flying through a galaxy continually fending off attackers. Your main objective is to land on enemy occupied planets, break through their defences and destroy their bases. You have heard other games described as fast and smooth but this is the game they will all be judged by. Game difficulty, options and keys are all fully user definable.
