Hitman: Blood Money

While it's certainly no R. Kelly assassination opera, you may find yourself crouching in a closet—or dozens of other hiding spots—as you stalk your contract prey. That's the glory of the Hitman franchise: Analyzing your environment, then executing the perfect kill, be it by piano wire to the Adam's apple or chandelier to the skull. Now that Hitman has a Vegas level, you also should be wary of death by blackjack—or, better yet, murder by lap dance.
