THQ announces Warhammer 40,000: Dawn of War II - Retribution, a standalone expansion for their sci-fi real-time strategy sequel they expect to release for Windows PCs in the first quarter of next year. Word is Retribution will allow you to choose between several races in the solo campaign, as they say: "Taking place years after the events in Dawn of War II: Chaos Rising, this title allows players to choose their perspective with the first multiple-race single player campaign in the Dawn of War II series. The first race to be revealed is the savage Orks, but no matter which race is chosen players will be taken on an epic journey through each story arc, revealing the answers to many questions left open in previous Dawn of War titles." They also add: "As well as the single player campaign, Retribution will feature new multiplayer units, maps and an entire new playable faction when it ships." The news is accompanied by a gameplay trailer which is also embedded below.
