Upcoming RTS Company of Heroes 2 will feature a weather system in which the cold can kill your troops. Much like real war, the enemy is sometimes as natural and simple as a cold front.
The idea is to accurately encapsulate the Soviet winter which reached extremes of -40 degrees F in 1941, and the effects that extreme cold had on warring troops. At those temperatures human skin will freeze in a matter of minutes, something that is portrayed in the game. The weather system was created by Relic’s Essence Engine 3.0 and its ColdTech system.
On winter maps, Infantry units exposed to the bitter cold will gradually freeze to death unless the player keeps them warm by building fires and garrisoning them in buildings. Dynamic blizzards will increase the effects of extreme cold making it even more hazardous to leave infantry in the open.
Ice, in CoH 2, has a unique texture, affecting vehicle and troop movement, but it can collapse or be destroyed from underneath troops and vehicles, plunging them into the hypothermic Russian waters. Over time destroyed ice will re-form due to the winter conditions in the game.
The snow is also a new feature in Company of Heroes 2. Snow can accumulate on buildings and vehicles, but it can also be melted or removed from objects by the player. Snow also has realistic depth which actually impacts troop movement and will retain persistent infantry and vehicle tracks throughout the match unless covered by fresh snow fall.
