Theatre of War 3: Korea invites players to delve into the intricacies of the Korean War, the first significant conflict of the Cold War era, often referred to as the Forgotten War. This immersive strategy game features two distinct campaigns set in the 1950s: the North Korean campaign from June 25 to August 20, and the American campaign from September 15 to October 8.
