Survival Horror buffs may recall Activision's attempt to jump on the Resident Evil/Silent Hill bandwagon, Nightmare Creatures. The game, set in 19th Century London, did enough to scare the kids, but it never quite became the next Resi.
It got a sequel in 2000 but the third game, Nightmare Creatures III: Angel of Darkness never got completed, possibly due to having the most generic name in history. Kalisto Entertainment went out of business before it could come to the PS2, Xbox or GameCube, and Ubisoft attempted to complete it, before ditching the idea.
The work lives on in concept form. The art features what looks like a protagonist design alongside two suitably horrific enemies. Always sad to see a game get scrapped, but hey, at least we have some funny pictures.
