It is a rotating cannon that uses compressed air to fire lead-filled bean bags at enemies, knocking them unconscious for a few dozen seconds, after which they will recover. It has a relatively low rate of fire, but deals good damage, capable of knocking out civilians with one shot and most enemies with just two to three shots. Both the bean bag launcher and the ammo for it are very rare to find around the town, but can be purchased at the weapon vending machines. It is one of the game's only three non-lethal weapons, the other being the stun gun and the flash grenade.
If used on burnt victims and people shot with the hunting rifle, the beanbags can bring them out of their crawling state and return them to regular functioning.
