This an explosive weapon that in some of the games can kill you in groups. It has the same explosive range as the grenade. It cannot be destoyed until shot by either the player or a devil. Thay appear in every game except Bounty Hunter. When used, they are set on the players exact position. Be careful when setting Barrels; you may trap yourself in the middle of a large stack, and then the only solution will be to shoot them, killing the player.
There are two upgrades for the barrels : double ammo and bigger bang.
