Chakan: The Forever Man is a Sega Mega Drive / Genesis video game published by Sega of America June 1992 and based upon a comic book by Robert A. Kraus. The game featured an uncommonly dark premise for the time of its release, which saw the home console market flooded with licensed (often from children’s cartoons) platformers. This Dreamcast sequel to the Genesis hit was under development by the original’s creator Ed Annunziata and his new studio AndNow. While there was no official cancellation declared, the project would be dropped and the lead artist would then reuse the majority of the concepts and designs for Blood Omen 2 which he was the lead artist and co-writer of.
