The SMG is a Handheld Ranged Weapon in Barotrauma.


The SMG is a two-handed medium-range, small-size firearm. It shoots rounds from a detachable magazine. The SMG functions both on board of the submarine and underwater, although its spread makes it unreliable at hitting distant targets.

It can be crafted by a Security Officer with the Weaponsmith talent, or alternatively can be bought on Outposts with a difficulty of at least 30%.


The SMG is held with both hands and must be loaded with an SMG Magazine to be used. As with all weapons and tools, using it is done by holding the Right Mouse Right-click to take aim, then by Left Mouse Left-clicking to shoot/use. Being an automatic weapon, the SMG can be fired continuously until the Magazine runs out of rounds by holding Left Mouse.

  • It has a single slot for ammunition which can contain one magazine (21 rounds).
  • It should be noted that the SMG has a large spread, which is made even larger for Characters with a Weapons skill lower than 50, greatly reducing its utility outside of point-blank range.
  • Like most two-handed weapons, the SMG has a Flashlight slot. The inserted Flashlight automatically turns on whenever the weapon is drawn.
  • Deconstructing a full SMG Magazine will yield 1 Lead and 1 Steel Bar. Deconstructing an empty magazine will yield only 1 Steel Bar. Empty magazines can be recycled by a Security Officer with the Munitions Expertise talent.
  • It can be stored in the inventory.
  • The SMG has a damage multiplier of 1.3, making it deal a lot more damage than other weapons using the same ammunition.

  • Magazines don't actually contain 21 rounds, instead they spawn bullets on demand as long as the Magazine has enough durability, like the Coilgun.
  • The SMG used to not be craftable, however in the 0.20 update it was made craftable by a Security Officer as a part of the talent rework.
