Condemned 2 is one of the nastiest experiences you are ever going to have in a game, but in a good way. It out-evils Resident Evil and is without doubt the most intense thing you will have played to date. The dark atmosphere, masterly use of sound effects and disturbing visuals combine to create the closest gamers have come in a very long time to experiencing the ultimate horror movie within a game.
If you could combine Saw, The Grudge, The Ring, The Eye (The Asian originals, not the remakes) and put yourself right in the middle of it while being in a bit of a punchy mood, you're starting to get close. Heed the 18 certificate well friends, this is one of the few games that really deserves it, yet it's still one of the most morbidly stand out games around right now.
