Styx: Master of Shadows is as pure a stealth game as they come. It forces you to be thoughtful and to observe, and rewards your patience with a satisfying tension. The abilities Styx has at his disposal are all great fun to use, and the levels are designed in such a way as to encourage experimentation and creativity. Ghosting through a level is exhilarating in ways few recent games can match, and Styx brings a substantially better story to the table than most of its contemporaries. Despite a few rough edges, Styx: Master of Shadows deserves a place alongside Metal Gear Solid 3, Hitman: Blood Money, and Mark of the Ninja as one of the best titles the genre has to offer.
