Though a spin-off of Microsoft's bestselling sci-fi shooter Halo, whose three installments have shifted over 25 million copies combined, Wars varies in many ways. Gone is Master Chief, the franchise's signature hero. The plot is set 20 years before Combat Evolved, the first Halo title, and it offers fewer compelling twists than its three predecessors. Voice acting and character development also prove underwhelming, as in the case of the tale's star, stereotypical tough guy Sgt. John Forge.
