Venting is a gameplay mechanic in DICE’s Star Wars Battlefront and Star Wars Battlefront II. It is used to cool down a weapon once it overheats or when the heating bar is partially full. It serves as a “reload.”
Overview
It is activated with X (Xbox), Square (PlayStation), and R or Left Mouse Click (PC). If the weapon automatically vents due to overheating, the heat meter will lower into a blue and yellow area. If the player pressed the vent button once the meter is in the blue area, the gun will instantly cool down. If pressed in the smaller yellow area, the gun will instantly cool down and will not heat for a limited duration.
