GameSpot writes: "Thanks to the Dawn of War series, real-time strategy games have begun to evolve past their roots of collecting resources, building structures, churning out an army, and eventually swarming opponents. The offense-minded series had a new chapter earlier this year with the full-on sequel, Dawn of War II, which introduced the Tyranids as a playable race, and the first stand-alone expansion for the sequel, Chaos Rising, will reintroduce the bane of the Emperor's existence, the Chaos Marines, as both a new villain in the campaign and a playable faction in multiplayer".
