Sentient tech merges with Corpus design to deliver this lethal sidearm. Fully automatic, it fires ricocheting, homing projectiles that release small clouds of Gas on impact. Alt-fire to release the entire clip without homing as a single burst.

The Cyanex is an Amalgam autopistol produced by the IconCorpusOn.png Corpus that incorporates SentientFactionIcon.png Sentient technology in its design. It fires bouncing homing projectiles that deal DmgGasSmall64.png Gas damage, complemented by its high status chance. Its Alternate Fire consumes the remainder of the magazine as a single automatic burst with deadly accuracy and low recoil, but without DmgGasSmall64.png Gas damage and the homing and bouncing properties.


  • This weapon deals primarily DmgImpactSmall64.png Impact on its Primary Fire and DmgSlashSmall64.png Slash damage on its Alternate Fire.
  • Primary Fire launches homing projectiles.
    • High DmgImpactSmall64.png Impact damage – effective against shields.
    • Innate DmgGasSmall64.png Gas damage – effective against Infested and Infested Flesh.
    • Homes in on enemies within 15°.
    • Projectiles ricochet once and can bounce off of enemies.
      • This allows one to fire at a wall and kill an enemy behind cover, or kill two enemies with one shot, supplemented by its homing ability.
    • Projectiles explode in 0.7 meter radius on impact with a surface or enemy.
      • Initial hit and explosion apply status separately.
      • Explosion does not need direct line of sight to deal damage and will penetrate walls.
      • Explosion can benefit from Mod TT 20px.png Fulmination (Mod TT 20px.png Primed).
      • Explosion inflicts self-stagger.
      • Explosion has linear damage falloff from 100% to 80% from central impact.
      • Homing ability of projectiles is hampered by a wide arc, and can often ignore close-range enemies unless aimed point-blank.
  • Alternate Fire unleashes all remaining rounds in the magazine as a single full-automatic burst with increased fire rate.

The Cyanex's blueprint can be researched from the Energy Lab in the dojo.

  • If punch through is equipped on the weapon, the Primary Fire projectile loses its homing capabilities after punching through an enemy, however, dart will fly toward closest enemy if punch through is enough to penetrate first target. I managed to get 4.5 punch through and it would chain to 1 enemy. It was tested on Corrupted Heavy Gunners. Not sure if it can chain to more that 1 additional enemy.
  • The Alternate Fire of the Cyanex will eject all of the remaining ammunition in the magazine in a single burst.
    • Base effective fire rate is 12.5 rounds per second.
    • If buffed with unlimited ammo such as from the Reactant Buff, the weapon will only fire its current magazine amount at a time, with small delays between each trigger pull.


  • Due to the pistol's tendency to run out of ammo very frequently it may be wise to use mods that increase reloading speed, such as Mod TT 20px.png Quickdraw and Mod TT 20px.png Stunning Speed.
  • Equipping a Riven mod with a negative Projectile Speed stat greatly improves the gun's tracking capabilities.


  • The weapon's name is very likely derived from Cyanide, a highly toxic chemical compound.
  • The Cyanex and Komorex.png Komorex are the only two Energy Lab Research weapons with a 12 hour build time.
  • The codex description for the Amalgam Machinist, an enemy that uses this weapon, refers to the Cyanex as a "plasma assault rifle" despite being a pistol.
  • Incidentally, Cyanex is also brand name for a collection of chemicals used in extracting various metals such as Ni, Co, Mo and Li.


Patch History[]

Update 30.7 (2021-09-08)

  • Fixed the Cyanex causing a parried reaction (knock back) versus certain enemies.

Hotfix 27.2.2 (2020-03-06)
Reduced the following AoE weapons Radial Damage Falloff from central impact that were all previously 90%:

  • Cyanex: 20%

Update 27.2 (2020-03-05)

Self Damage Changes

We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.

The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.

With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.

In addition to Self Damage being removed, some of the more powerful AOE weapons without Self Damage presently will have the Stagger added, but it should only be noticeable in cases of extreme inaccuracy on the player’s part. The Weapons include:

  • Cyanex

In the original Dev Workshop, we said:
As a result of this overall systemic change, Weapons with Stagger will be getting approximately a 20% buff in Damage, with any weapons with AOE receiving a 50% Radial Damage Falloff from central impact.

This is no longer accurate after continued testing. What we are doing now is:

No damage buffs have been added, but any weapons with AOE are receiving ~20% increase in Radius. Additionally, AOE weapons are receiving a 90% Radial Damage Falloff from central impact. This means on the very outer section of the explosion Radius 10% of the Damage will be dealt. Tactics will be deadly - aim true, Tenno.

Why: Several players brought up the history of the Tonkor and we want to make sure we ship this change in a place that’s conservative in its starting point from a balance perspective. The complete removal of Self Damage does change the pace of destruction with some of the game’s most powerful weapons, so we want to make sure we can iterate upwardly instead of releasing a bonanza of explosions with no other choices.
