This is a new game coming out on the PS3. Doesn't look like it will be coming out for the 360. The scheduled release date is June 14, 2013.
Essentially, this is a zombie apocalypse game, except that they've got a different take on the "zombies." They're actually humans that have been mutated by something, but they behave very much like zombies. Another difference is that there are different types of mutants with different strengths and weaknesses. In that sense, it's somewhat similar to Left for Dead.
However, the gameplay looks intriguing. There appears to be tons of ways to kill these mutants (or other humans) with objects that exist in the environment. And I'm not talking about just picking up a 2x4, knife, etc...in one of the gameplay videos below, for example, a mutant is killed by the player smashing its head onto a desk. The number of possibilities simply shown in the videos below make me wonder how difficult the controls are.
Additionally, you have the ability to collect certain items and make other useful items out of them. Crafting a shiv for stealth skills is one option. Attaching scissors to the end of a baseball bat is another. I'm not sure how in-depth this customization goes, but it seems interesting.
One other thing that I read is that there is no standard pause feature, nor can the player access their inventory at any time. There are checkpoints which will save your game, but you can not pause the game or access your inventory unless you are hidden in a safe spot. Similarly, accessing your inventory menu or crafting a new item does not stop the action around you, so you have to hide in order to complete these tasks.
Basically, it's a survival horror game that seems to be implementing some new features that I haven't seen in many other games.
