Packaging for Sinclair QL Zapper with Eagle Instructions for Sinclair QL Zapper with Eagle

Zapper was published by Eidersoft and written by Janko MrsicFlögel. It is loosely based on the well-known Arcade game Space Invaders. In the game, you are defending a planet from swarms of aliens descending from above - there is nowhere to hide, just you and your trusted laser weapon. Fast and furious, the aliens can get past you to attack again from above and the more you shoot, the faster they move. Featuring excellent graphics, the game is controlled by cursor keys or cursor emulating joystick. The main issue with the game is that you can only fire one missile at a time.

Advertised features included:

  • 100% Machine Code game
  • 8 Levels of Multicolor Graphics
  • Super Smooth High Speed Action
  • Sound and High Score
  • 65K Code Length
  • Load Time 1 Min
  • Supports TV/Monitor
  • Joystick/Cursor

The program was originally advertised on its own, but in October 1985, Eidersoft started to bundle it with Eagle, for the same price.
