Relic and THQ have announced the second standalone expansion to the Warhammer 40k-themed RTS Dawn of War 2. The expansion will be called Retribution, and will introduce the series' first multi-race single-player campaign. The first race announced is the Orks, but players will be able to choose other races to play through the campaign as well, meaning you can finally play as something other than Space Marines in the single-player game.

Multiplayer also gets extras in the form of new units, some new maps and a whole new playable race to fight with. There's no word out of Gamescom yet as to exactly which race that is, but given that we've played as Orks, Space Marines and Eldar in the series before, playing as the Tyranids is a pretty good guess (edited) already in the game. Commenters are guessing Dark Eldar. We'll find out for sure when the expansion is released -- it's scheduled for Q1 2011.
