Company of Heroes 2 is a real-time strategy video game developed by Relic Entertainment and published by Sega for Microsoft Windows, OS X, and Linux. It is the sequel to the 2006 game Company of Heroes. As with the original Company of Heroes, the game is set in World War II but with the focus on the Eastern Front, with players primarily controlling the side of the Soviet Red Army during various stages of the Eastern Front, from Operation Barbarossa to the Battle of Berlin. Company of Heroes 2 runs on Relic Entertainment's proprietary Essence 3.0 game engine. In January 2013, Sega acquired Relic Entertainment and along with it the Company of Heroes intellectual property from THQ. The game was released on June 25, 2013 in North America and Europe.
