Into The Dark releases for PC
Peter must battle against mutants, zombies and various other nasties as well as solving puzzles and running through environments involving hookers, sex and porn (at least according) to the trailer. As you traverse the environments things will jump out and suddenly attack in a game that has won various scariest game awards from just showcasing only one level last year.
Into the Dark is available on most PC downloading sites and a retail version will be made available in 2013.
