Warhammer 40k: Dawn of War II: Retribution
A new RTS in Warhammer 40k universe is out: Dawn of War 2 Retribution.
The game seems pretty good. See this review by Gametrailers.com:
All races are now playable however the story is not very punchy.
The game dynamics are not as good as Supreme Commander 2 or Starcraft 2 but this stand alone expansion is the best Warhammer 40k has brought to PC gaming (8/10).
