In snowy environments, snow could build up on the weapon and gradually melt from the barrel system due to the warmth generated by firing. Mud Gathered around tracks, Wheels , Snow could melt adound engine areas. However, this would be purely cosmetic—Guns wouldn’t overheat to the point of malfunction. Neither would the Vehicles. This small detail would enhance immersion without impacting gameplay performance.
