Ghostbusters: Sanctum of Slime on PlayStation 3 features a brand new storyline in the poltergeist police's universe written by the editor of The Real Ghostbusters comic, Tom Waltz.
The story begins almost 4,000 years ago with the deaths of an ancient demon called Dumazu and members of the cult that worshipped him. It then jumps forward in time to the present day, showing you what happened to Janosz Poha, the curator of the Manhattan Museum of Art who had been possessed by the demon, Vigo, in the Ghostbusters II film.
Poha, it turns out, was sent to a psychiatric institution but released years later. While there, he met a man named Ismael, who claimed to be the last known member of the cult that served Dumazu. Ismael tasked him with locating a shard of the Relic of Nilhe, a mystical artefact with the power to resurrect the evil entity.
Poha found it, and as a result New York became with ghastly ghouls. This is where you come in as the leader of a team of rookies battling the reign of ghostly terror taking over the streets of the Big Apple.
