I think it's got the potential for some good backstory:
'A spectacular, creative, and unflinching realisation of a Clive Barker nightmare for next-gen console platforms and PC, Clive Barker’s Jericho is a new supernatural horror concept with story by the master mythmaker, novelist and filmmaker Clive Barker.
Jericho deals with the mysterious reappearance of a lost city in a remote desert. When a form of evil that goes right back to the dawn of days resurfaces from there, a Special Forces squad, trained in both conventional warfare and the arcane arts, is sent in. Their mission: Hunt down and destroy the evil that lurks at the heart of the city before it destroys humanity.
“Players will constantly be given new challenges, new environments, and yes, new horrors and abominations to face every step of the way,” continues Barker. “However, unlike a conventional game in which the characters are attempting to escape at the end of their ride through Hell, our protagonists have a much more difficult task. The closer they come to the end of their trek into darkness, the nearer they get to the source of that darkness: Evil Incarnate, we’ll call it for now...”
Clive Barker’s Jericho is designed as an action horror title that will up the stakes in visuals and phantasmagorical special effects. Mingling the darkest elements of Barker’s horror fiction and films with an ambitious, age-spanning story, aimed at mature gamers, fans of Clive Barker and horror fiction enthusiasts. '
