Editing Realm of Impossibility (section)

==Development==
Edwards worked at [[Boeing]]. When his job changed and he was no longer programming at work, he became interested in the home computer market as a way to continue programming. Checking over various models at a local computer store, he purchased an Atari after seeing ''[[Star Raiders]]''. After having the machine for a while he began programming on it and, at the suggestion of a long-time friend, wrote a simple program in [[Atari BASIC]] to sell locally as a [[tax dodge]].<ref name=interview>{{cite journal |url=http://www.atarimagazines.com/rom/issue4/interview.php |title=Interview: Mike Edwards |journal=ROM Magazine |date=February–March 1984 |page=12 |first=Peter |last=Ellison}}</ref>

He then began programming his first game, ''Attack at EP-CYG-4'', a [[shoot 'em up]] which allowed two players at once. This was licensed to another company for sale on [[game cartridge]], with Edwards helping with the port. He then began work on a maze game, which became ''Zombies'' after adding in 3D effects at the prompting of his partner.<ref name=interview/> The game contained several levels of increasing complexity. The last level, "The Realm of Impossibility", contained a number of optical illusions similar to those popularized by artist [[M. C. Escher]].<ref name=raving>{{cite journal |url=http://www.atarimagazines.com/rom/issue4/raving_reviewer.php |first=Tim |last=Reekie |title=The Raving Reviewer |journal=ROM Magazine |date=February–March 1984 |pages=16}}</ref> Surfaces that appear vertical turn out to be horizontal, and other illusions can confuse the player.

The success of the original release prompted [[Don Daglow]] to acquire the rights for EA. Minor changes were made to the game, new levels were added, and a new soundtrack was added, written by Dave Warhol who had worked with Daglow on the [[Intellivision]] game design team. Officially renamed ''Mike Edwards' Realm of Impossibility'', it was released not long after the original BRAM release, with the box cover touting "Deluxe Edition of The Classic Game Zombies".<ref name="atarimania">{{cite web|title=Realm of Impossibility|url=http://www.atarimania.com/game-atari-400-800-xl-xe-realm-of-impossibility_4312.html|website=Atari Mania}}</ref> The game was part of the "third wave" of titles introduced by Electronic Arts after its founding in 1982.{{citation needed|date=February 2018}}
