Rising Storm is the official expansion pack for Red Orchestra 2: Heroes of Stalingrad, a historical World War 2 first-person shooter for PC. Originally created as a collaboration between some of Red Orchestra’s best community developers and Tripwire themselves,  was formed from the core mod team of Rising Storm.

Since Rising Storm‘s release, Antimatter Games worked to deliver free post-release content for the game in four major updates, providing new maps, weapons, game-modes and more to the community.
