Gatling Arm

This trusty old machine gun shoots almost without stopping if cold drinks are poured over it in time.

Overview

Minigun deals low damage by default over a fairly long distance (7000 max), however, with every second fired, the minigun's rate of fire increases up to 1200 (from the initial 350).
You need to spend about 5-6 seconds on the maximum promotion or prepare it in advance on the RMB.
If you do not shoot, then the rate of fire begins to gradually fall.
There are no ammo. The weapon is overheating. If the weapon is completely overheated, then the character is forced to start cooling, which lasts 5 seconds.
But you can cool the weapon without reducing its ammo to zero - then it will go faster.
There is no recoil, the spread is quite strong.
If the weapon is not spun, then there is always a short delay before firing.
Weapon passively cools down over time when not firing.

You can hold down the RMB to start spinning the minigun without firing, thus preparing it for a fight and not wasting ammo.
