What 3-D Zapper is

3-D Zapper was developed by James Wickstead Design Associates. It is available on Atari 2600 only.

The premise, in the publisher's words

Unreleased game programmed by Todd Marshall. Within existing internal documents the given title is "3-D Zapper," though the prototype cartridge itself has an end label that reads merely "3-D Demo," while the PCB within features a sticker reading "3D Space" and a date of December 13, 1982. Internal documents describe the game briefly as follows: "This game contains the elements of a typical shoot-em-up spree game. The unique elements of this game are: (1) that the invaders perform erratic randomized dances in a three-dimensional field. (2) The 3-D operation of the gun. (3) The invaders themselves are particularly tailored to provide an exciting 3-D effect on the ATARI VCS."
