Tripwire Interactive today announced a new World War II PC game, Red Orchestra: Ostfront 41-45. Tripwire will deliver its award-winning first person shooter via Steam, Valve's online content delivery system. The original Red Orchestra won Nvidia's "$1,000,000 Make Something Unreal" contest. Red Orchestra: Ostfront 41-45 is a standalone follow-up, built on Epic's Unreal 2.5 EngineTM, that introduces new gameplay and features.

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.
