This another game which falls down on the keyboard layout - all along the top row. The game itself has fairly simple graphics, the explosions being reasonable, but inferior to those of Anirog or Ocean. It is reasonable as a game, but due to keys, only a joystick game really (Kempston and Sinclair). Three skill levels and a 2 player option are also provided.
With this version one or two players can play, with a choice of 3 skill levels. There are missiles for your defence in this comparatively tame version. Every 1,000 points scored awards you an extra city. The cross hair moves quickly and smoothly, and firing a missile results in a realistic explosion with good sound too. I like the colour, and it is a good noisy version, but its addictive qualities are slight, and its appeal wears off after a couple of hours.
