Players moving through deep snow will move at a reduced speed. Bonfires protect soldiers from the cold at the expense of enemy detection. Since many battles in the Eastern Front occurred in winter weather, troops can die of frostbite if caught in the outside during blizzards. Weather conditions are a major factor in gameplay, with movement and action penalties applied to players' units. Essence 3.0 also incorporates an innovative weather-simulating technology known as ColdTech and destructible environments. In contrast to traditional unit visibility, TrueSight more accurately represents a unit's visibility range based on environmental conditions and type of unit.

One such improvement is the new line-of-sight technology, TrueSight, which aims to better emulate troop visibility in real combat. The game is built on Relic's proprietary Essence 3.0 engine, which showcases new improvements compared to Relic's previous games. The campaign features the Soviet Red Army as a new faction and takes the player to various stages of the Eastern Front campaign, from Operation Barbarossa to the Battle of Berlin. 6.3 Company of Heroes 2: British Forces.6.2 Company of Heroes 2: Ardennes Assault.
