Will you carve a bloody swath of hateful vengeance through the crumbling city of Dunwall, or will you stay your blade and liberate her from the shadows, bringing all who conspire against her to poetic justice? Dishonored gives you the choice to play it your way; whether going in sword swinging, slinking through shadows and across rooftops, or using magic in a variety of ways.
I'll avoid talking about the story, but I will say that it is both compelling and branching, with varying endings depending on how you choose to play the game. The same goes for the two story based DLC included in this version, The Knife of Dunwall and The Brigmore Witches.
The art style is unique, and while not everyone will like it, I think it fits the atmosphere rather well, and the voice work is fairly good, though not always perfect. As for the gameplay, it's crisp and responsive; the controls are good and feel pretty natural, and the game has good hit and stealth detection.
The one real negative of this game is the Trials of Dunwall DLC (also included). The achievements are a real bastard, and several are essentially luck based. They may only take you a few hours but could also take over a dozen, so completionists might want to keep this in mind. That said, I believe the main game and two story DLC more than make up for the difficult completion. With a sequel coming soon, I highly recommend this game if you haven't played it yet; it's one of my favorite games in years, and easily one of the best I've ever played.
