The Moloch is a large jellyfish-like creature that manifests in Barotrauma.


Molochs' large dark blue shells cover most of their main bodies, also known as their "core", to provide protection from their front. Moloch's cores are mostly made up of their "ballast sac", which pulsates to allow movement underwater.
Above the Moloch's core, three elongated dark brown tentacles protrude from under the shell. Below the core, thin black tendrils known as the "skirt" trail the Moloch, providing extra protection.
Molochs are blind, and rely on echolocation to navigate. The sounds emitted from this are strikingly tuneful notes, which become stronger and higher in tone when the creature attacks.


Molochs are agitated by noise. If attacked in melee by a reckless diver, the Moloch will strike back but won't persist, unless it is actively chasing the submarine. If the submarine and its crew stay silent for a few seconds, the Moloch may lose them and stop pursuit.
Impact with a Moloch, or even just a corpse thereof, is especially damaging to the submarine's hull and will easily punch holes in it, causing floods.
Molochs will deliberately attempt to ram the submarine. Despite their persistence to sink the submarine, they tend to be unable to match their speed, which makes fleeing a viable option.

Combat strategies

Coilgun Piercing and Exploding Ammunition will damage the core through the shell, and is the best option when attacking from above.

Since the shell of a Moloch significantly reduces the efficiency of regular attacks from above, if lacking any piercing or exploding ammunition it is strongly recommended to shoot them from below for maximum efficiency. A Railgun will take three to four shots to kill it. If a player manages to shoot it under its shell, it will usually be an instant-kill.

  • Moloch.png Moloch "bosses" are the targets of "Killing a Moloch" Missions.
    They are 15% bigger than regular Molochs, have higher vitality, inflict +15% affliction damage, and cause more damage to hulls.
  • Black Moloch.png Black Molochs, as their name suggests, have a darker shade to their shell and limbs, and are encountered in Random Events.
    They are 15% bigger than regular Molochs, have higher vitality, inflict +15% affliction damage, and their attacks have +15% range. Their ramming attack has a large area-of-effect with a light EMP effect.
  • Moloch Baby.png Moloch Babies lack any offensive capabilities, but will emit a very loud noise when hurt, calling for their mother to defend them from a very long range.
    They drop 1 Alien Blood.png Alien Blood and 1 Swim Bladder.png Swim Bladder.


  • The Moloch Boss' internal ID used to be "Molochboss"; in version, it was changed to "Moloch_m".
  • Before version, Molochs were unable to damage players, but tried to regardless. This resulted in the popularity of a 'rush' strategy to deal with them: divers would swim to the Moloch and strike it with the least efficient weapon, distracting the creature from the comparatively vulnerable submarine and slowly wearing out the monster. The issue was fixed in, and the strategy abandoned.
  • Interestingly, the Moloch's code doesn't include direct damage values against structures, instead transferring kinetic energies to yield the same result and create hull breaches.
  • Molochs bear a resemblance to the extinct Dollocaris as it has a similar body plan, and may have been based on them.
  • Black Molochs when nearby the sub cause the navigation terminal to display heat as if there are volcanoes attacking you
  • Molochs are sometimes found instead of an artifact at the end of salvage missions in Mission Mode or Campaign, as they emit the same kind of infrasonic signals. Killing the misleading creature will still be considered a success.
