Nightmare Creatures review. Classic Game Room presents a CGR Undertow review of Nightmare Creatures for the PlayStation developed by Kalisto Entertainment and published by Activision. With a story dating back to the Great Fire of London in 1666, Nightmare Creatures is a horror-themed action game with a very interesting premise. Nearly 200 years after the Great Fire of London, an occultist is trying to once again bring terror to the city. It's up to a priest and the daughter of an American to stop his nefarious plans. Cut zombies in half, jump over crumbling bridges and shoot werewolves in this excellent PSX hack-and-slash game. This video review features video gameplay footage of Nightmare Creatures for the PlayStation and audio commentary from Classic Game Room's Derek.
