Clive Barker's Jericho is a FPS. There's another FPS that's just been released on the Xbox 360 and it's the best game of the year, probably the best game on the Xbox 360 and possibly the best FPS ever made. So games like this are a bit unnecessary now. HOWEVER, if you're still looking for a new shooter to play, particularly a scary one, then Jericho MIGHT be what you're looking for.
If you haven't got The Darkness, stop reading this and go and buy it. If you've finished The Darkness and want more gruesome, horror shooting, you should know that Jericho plays very similarly to that game. It has a really similar feel and the title screen is exactly the same.
Apart from 'the feel', Jericho isn't as good as The Darkness. To be fair, not a lot is, but Jericho is so similar yet falls so far behind in a lot of ways.
But first, the positives, of course. It has a really cool QTE bit that requires you to hit buttons that flash up on screen to trigger certain events. If you miss them, you die. It's been done so many times before (see Dragon's Lair, Shen Mue, Resident Evil 4, etc...) but it's still refreshing when done properly. Jericho sees a BRILLIANT example of QTE at the end of the demo and it got my heart racing a little bit.
The game also looks really nice and creepy. There's a lot of detail in the environments and the lighting is gorgeous.
HOWEVER. The enemies are all the same, and boring. The level is really linear, with no option for exploration off the beaten track. And it's yet another FPS in the year of shooters. Give me a fucking PLATFORM game or something, please.
