Dead Space Wiki

The Medusa is a Necromorph form found exclusively in Zero-G environments on Tau Volantis. Like the Alien Necromorph, the Snow Beast, and the Nexus, the Medusa also seems to be a Necromorph based on a native lifeform from the planet.


Appearing only in zero gravity environments, Medusas are best to be avoided. If the player gets close, they can deliver a devastating melee attack with one of their four limbs. They can also fire projectiles that home in on targets. Therefore, it is better to engage them at long range and kill them before they can attack.

It is possible that the Medusas best served their purpose in the oceanic terrain of Tau Volantis during the original Necromorph outbreak, and that the ones encountered in Dead Space 3 were encased in ice when the planet flash froze.

Combat Strategy[]

  • Most of the time, it is wiser to conserve ammunition and simply maneuver around them.
  • Shoot the yellow sacs on their limbs (destroying the main sac will launch two or more projectiles).


  • In Greek mythology, Medusa was one of the three Gorgons and was said to be so ugly she could turn anyone she looked at into stone. This name is fitting, given the Medusa's grotesque appearance.
    • A Medusa is also the name given to the free-swimming stage of Cnidarians such as jellyfish, normally the reproductive stage of a sessile polyp. The Necromorph's physical appearance seems to support this, as they resemble the stationary polyps.
  • Medusas have a similar appearance and behavior to Nemacysts from the Gears of War series.
  • If a Medusa finishes off Isaac/Carver with its limb during a Zero-G flight, their bodies will be torn apart while their legs continue to drift off-screen with boosters still active.
  • If one kills a Medusa without severing any of its limbs or popping the main sac, its body will twitch violently, causing the main sac to explode. In some occasions, the corpse will mysteriously vanish, most likely due to a glitch.
