$20 Off Dishonored ($39.99)
Platforms: Xbox 360 / PlayStation 3
Stealth, sabotage, and steampunk! There's a lot to like in Dishonored and there's a good reason it's been nominated for a great many game of the year awards. It's got shades of Bioshock in terms of atmosphere and story, but plays like the classic stealth-action game, Thief. If that sounds like something you might enjoy, you should probably pick this one up.
