Probably the definitive 'scramble' game for the Spectrum. Four rings of defence surround the alien base, each with its own problems of landscale. Missiles take off continuously guided by radar units (excellent animation) which get more accurate if you fail to destroy enough of them. Special feature allows you to reprogram the game to make your own landscape and alter the enemy's defences. Highly recommended. Joystick: Kempsoft I.
