Toxic to the core, Nox lobs exploding poison goo at enemies. Rupture his helmet to expose his head but beware of the unleashed noxious gasses.

The Nox is a type of Grineer "Chem Strike" unit. They wield a poison-filled heavy gun that shoots blobs of DmgToxinSmall64 Toxin sludge which stick to targets and surfaces before exploding. Bloated and disfigured by the very chemicals they wield in combat, these vicious warriors wear crude, heavily armored suits that both protect them in the form of Overguard and serve to contain the noxious clouds they emit.

Breaking the glass cover protecting their heads removes their defenses, but releases the poisonous aura to their surroundings. Beware of their final moments, as they explode into a lethal cloud upon death.


  • The Nox wields what is effectively a primary version of the Stug Stug. As such, its projectiles have a low range and arc, which causes the Nox to have difficulty targeting his enemies from range.
  • To counter its ineffectiveness at range, the Nox can charge forward, causing all in his path to be knocked down as well as allowing him to close the distance for his gun to be more effective. They only do this as a last resort, however, once their glass helmets are destroyed.
  • Combined with the ability to emit a constant 3-m aura of DmgToxinSmall64 Toxin damage when the helmet is broken, the charge allows the Nox to knock down Tenno, then deal damage directly to their health.


  • Breaking the Nox's glass helmet will immediately remove all of their Overguard.
  • The Nox's projectiles can stick to the player and inflict a slowing effect, similar to a DmgColdSmall64 Cold status effect, though less severe. The sludge can be shaken off by rolling.
  • At base level, the Nox's projectiles on contact deal 20 DmgImpactSmall64 Impact. Blobs tick for 3 DmgToxinSmall64 Toxin damage every second for 4 seconds. The blob explodes after 4 seconds, dealing 30 DmgImpactSmall64 Impact in an AoE.

  • The goo stuck to the players will still slow them even if it's from a friendly Nox (such as the allied ones from an invasion).
