Very good game. Amazing visuals and audio pulls you in!
The Darkness could have been a bit more polished in the game play. There are some really annoying glitches that cause a player to have to restart a chapter from the beginning if they want to get some of the achievements. This just happened to me this morning. Argh... wish I would have known how to handle the Warburton side mission.
Overall it's a great game. I paid full price for it, but now that it's starting to come down in price it's worth checking out.
