When the trigger of the gun is held, an invisible cloak forms on the player. This will lower the temperature of the gun but the cloak lasts for a short while and will freeze up the gun if it's on too long. If the gun freezes, there will be another lenghty animation where the character breaks the ice and shakes the gun to clean it of the icy remains. While cloacking, the player cannot run or melee, so the invisibility is mainly used to avoid attacks or for aproaching to an enemy. Also, the more cold the gun gets, the weaker its shots become.
