Dead Space with Co-op. Before anybody says the horror element will be gone with this RE-ish move, I gotta say it won't: cheap scares won't fade away with a mate beside you to share the shock. Gotta defer to Bill Yahthzee description of DS:
"And then there are horror games where the guy in the spooky mask goes "abloogy woogy woo" while standing on the far side of a brightly lit room before walking slowly over to you plucking a violin and then slapping you in the face with a t-bone steak."
It's still a fun game with an intricate and surprisingly intriguing in a "I want to know more" way, so I'm hoping for the best.
