IO Interactive made its mark on the videogame world with the first Hitman game in 2000 and planted a flag with Freedom Fighters in 2003. The world, especially Europe, loved Hitman, and rightly so. IO has designed a stealth game that, while suffering from some easy-to-notice flaws here and there, boasts some of the most distinguished and well-honed level design in any game of its kind. Perhaps equally important, IO gave birth to a long-lasting, brooding iconic antihero with Agent 47. With the third game in the series, Hitman: Contracts, IO hit a lull, as the team was simultaneously working on Blood Money and creating the newly fangled engine on which this new game was built. Contracts looked good enough and explored a dark, devious theme that hadn't been done before, but it played like all the others. This fourth game does several things to improve the series, both from a presentation and a playability perspective.
