The original Red Orchestra reshaped tactical multi-player gaming and was amongst the top 10 most-played MP games for years. Tripwire Interactive delivered new content, free of charge, for 3 years after launch. RO2 will expand on that, adding a whole new take on single-player, new MP modes and a new MP campaign, which is why PC Gamer declared it "one of the Top 10 games for 2011".

The new single-player campaigns will allow the player to experience that legendary gameplay, set in one of history's most brutal battles, across full campaigns from both the Russians' and the German's perspective. Fight through iconic locations with your squad and grow to take command of your men, earning the right to lead them in one of the world's toughest combat environments: the Battle of Stalingrad.
