The brute is a Boss that is extremely hard to kill. They will come and go at a fixed time of 2 minutes and 30 seconds. The amounts of brutes that come depend on how many players there are. If you manage to kill all of the brutes it will give you a bonfire sale and max ammo. If you don’t kill them all but you kill one or more it will give you a fire sale and max ammo, if you don’t kill any then you will get max ammo.
