Overheating is just like reloading, an animation you’re locked into before you can fire again. Every special weapon before required reloading and ammo bricks. Heat weapons can be very good because of the cooling system instead of reload. You instantly get auto-cooling without a perk being used up from not firing the gun. Swap off the special heat weapon for a handful of seconds and bam you’ve got a full mag again. You can also partial vent and it takes less time to get your whole magazine back depending on its heat, whereas reloads take the same amount of time whether you’ve fired three bullets or twenty. We have hundreds of regular reload weapons, it makes sense to have a few new heat ones in the dungeon for this expansion.
