Back around 1985 time, Antony Crowther was working on a game based on the Red Arrows, which is another GTW which we have within our archives. In an interview with Commodore Horizons, Antony suggested that his next project would possibly include a game based on the Ray Harryhausen film, Clash of the Titans.
It was a very brief mention, and it seems unlikely that the idea never fully came to use. However, a game called Gryphon surfaced and could have been what the game turned out to be.
Maybe Gryphon started out as a completely different game? We hope to find out soon from Antony himself if he can recall anything and if this game ever got off the ground.
