Platform: Xbox 360
Condemned is a game that was criminally overlooked as an Xbox 360 launch title in favor of the Perfect Dark sequel, but for me, Condemned was the real system seller. I loved the intense and gritty atmosphere, the lighting effects, the shadows and legitimately horrifying gameplay.
There are so many moments that stand out so well for me in this game that it remains one of my favorites today. It would be higher on my list if not for the weird final chapters. But it's still a fantastic game in spite of this.
Taking an alternate approach to the defenseless run and hide gameplay mechanics of more recent titles, Condemned features one of the most brutal and well-implemented hand-to-hand combat systems I've seen in a horror FPS. The brutality of the game doesn't pull any punches at all and the perspective definitely adds to that.
If viewed from a third-person viewpoint, I think the atmosphere would have been lost in what may have looked and played like a half-baked action game.
