Barrel is currently disabled from the game. Assets for this exist within the game files, but will not be encountered through normal gameplay.
Barrel is the chestpiece of the Barrel Set, a costume armor set. When combined with Barrel Lid it makes the player appear partially hidden inside a barrel while crouching.
It's found in the game files, but is not obtainable through normal gameplay. It can be spawned using admin commands.
