Red Orchestra lets players choose from 28 infantry weapons or crew one of 14 different fully-realised vehicles on the Russian Front between 1941-45. The combination of roles across more than one dozen maps, based on real-world locations and battles, allows Red Orchestra to finally achieve its goal of delivering a full first-person, WWII combat simulation.

"Digital content delivery is the future of gaming, and we are very excited to be a part of that future" said Tripwire Interactive President John Gibson. "Working with Valve to release the game over Steam allows Tripwire to remain independent and keep control of the games content and development. This allows Tripwire to continue to offer our fans the same uncompromising level of realism, authenticity, and gameplay they have come to expect from Red Orchestra while continuing to innovate and push the boundaries of the military FPS and simulation genres."

"We're pleased to have the winner of the 'Make Something Unreal' mod tournament bringing their full-fledged game to market on Steam," said Jason Holtman, director of business development at Valve. "This shows that a talented and passionate group of developers can take a game from concept to public distribution outside of the traditional publishing and funding model and deliver it to over 6 million customers."
