HeroQuest © 1991 Gremlin Graphics Software
Unreleased game.
In December 2012, Chris Shrigley, who programmed the game, released the source code for educational purposes to the public and said: "I programmed this as a quick freelance gig for Gremlin Graphics during the summer of 1991, just after leaving Eurocom, and waiting to go to the US to work for ACME Interactive. I programmed this in my back bedroom, with the windows open, and the sunshine streaming in, listening to Radio One’s “Our Tune”. Good times!"
