Ghosts ‘n Goblins 3D (AKA Makaimura 3D in Japan) is a cancelled chapter in the titular Capcom series that was planned in 1994 for the original Playstation, 3 years after the release of Super Ghouls ‘n Ghosts for the Super Nintendo. As far as we know this canned PS1 game was never officially announced by Capcom (but they did announce Ghosts ‘n Goblins for Nintendo 64) even if rumors about a 32-bit Makaimura were around at the time. In September 2020 a former Capcom artist shared a few pieces of concept art on Twitter, but later removed their message: those drawings are preserved in the gallery below, to remember the existence of this lost game. By looking at one of the remaining drawings, we speculate the game may have had an isometric top-down view.
It seems Kouji Ogata (at the time a Capcom employee who worked on the opening of the SFC version of Super Street Fighter II) was originally in charge of Ghosts ‘n Goblins PS1 character design, but was later replaced by someone else (Pink Head?) before the project was just canned.
