Warhammer 40000 Dawn of War II: Retribution (Game)

Warhammer 40,000: Dawn Of War II - Retribution is the stand-alone second expansion to Warhammer 40,000: Dawn of War II, part of the Warhammer 40,000: Dawn of War series of real-time strategy computer games. Set in Games Workshop's Warhammer 40,000 fictional universe, the single player campaign is playable with multiple races.
As of January 2011, the Eldar, the Space Marines, the Imperial Guard, the Chaos Space Marines, the Orks and the Tyranids have been announced as playable races in single-player.
There were speculations that the new playable race would be Imperial Guard and/or the Inquisition, due to the Inquisition triple lined "I" used in the word "Retribution" in the game trailer; in addition, the expansion's wishlist icon in the Steam system features a female Witch Hunter Inquisitor. On December 21, 2010, German PC gaming magazine Gamestar revealed the new race would be the Imperial Guard.
A multiplayer beta of the game was launched on Steam on February 1st 2011 and ended on February 25th.
