This game was refreshing and different when it came out back in 2007. Playing it for the first time on Xbox 360 back in 2009, it was unlike anything I had played before, and admittedly, since. It made such an impression on me that I jumped on the opportunity to buy it again on Steam and play it on the PC. It is easily the one of best story-driven FPS games I've played. It has a unique and creative atmosphere and story that in my opinion makes it one of the best games of the 2000's. My only complaint is that it's not the longest of games, although most will likely get a longer play time than me as my steam record reflects my second playthough (most people's first playthoughs will most likely take 15-20 hrs).

It's a no-brainer to buy, especially with the current sale price of $3.99. Add this masterpiece to your steam library.
