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 Corpus that incorporates Sentient technology in its design. It fires bouncing homing projectiles that deal Gas b Gas damage, complemented by its high status chance allowing it to spread Toxin b Toxin damage with its procs. Its Alternate Fire consumes the remainder of the magazine as a single automatic burst with deadly accuracy and low recoil, but without Gas b Gas damage and the homing and bouncing properties. It can be researched from the Energy Lab in the dojo.

This weapon deals primarily Impact b Impact on its Primary Fire, and Slash b Slash damage on its Alternate Fire.


  • Primary Fire launches homing projectiles.
    • High Impact b Impact damage – effective against shields.
    • Innate Gas b Gas damage – effective against Infested and Infested Flesh.
    • Homes in on enemies within 15° degrees.
    • 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.
    • Creates a 1 meter radius explosion on impact.
  • Alternate Fire unleashes all remaining rounds in the magazine as a single full-automatic burst with increased fire rate.
  • Very high status chance.
  • Mod TT 20pxMagnum Force's accuracy penalty is minimal on this weapon.


  • Primary Fire:
    • No Puncture b Puncture and Slash b Slash damage – less effective against armor and health.
    • Innate Gas b Gas damage – less effective against Flesh and Cloned Flesh. Furthermore, Toxic Ancient's aura provides 80% damage reduction to Gas b Gas and 100% to Toxin b Toxin.
    • Extremely low accuracy, although mititgated by its homing capabilties.
    • Homing ability of projectiles is hampered by a wide arc, and can often ignore close-range enemies unless aimed point-blank.
  • Low magazine size for its fire rate; requires frequent reloading.
  • Projectiles have travel time.
  • Very low critical chance.
  • Lowest critical multiplier of all secondary weapons in the game.
  • Fairly slow reload speed.


  • If Punch Through is equipped on the weapon, the Primary Fire projectile loses its homing capabilities after punching through an enemy.
  • The Alternate Fire of the Cyanex will eject all of the remaining ammunition in the magazine in a single burst
    • If buffed with unlimited ammo such as from the Reactant Buff, the weapon will only fire its magazine amount at a time, with small delays between each trigger pull.
  • The Impact b Impact component of the Primary Fire's base damage is not considered for the Gas b Gas proc damage calculations.


  • 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 20pxQuickdraw and Mod TT 20pxStunning Speed.
  • Equipping a Riven mod with a negative Projectile Speed stat greatly improves the gun's tracking capabilities.
  • Equipping Toxin b Toxin mods, such as Mod TT 20pxPathogen Rounds or Mod TT 20pxPistol Pestilence will greatly increase the Gas b Gas status proc damage, even if other elements are added to form Corrosive b Corrosive or Viral b Viral.
  • While the damage is fairly low per hit, the Cyanex is ideal for a Mod TT 20pxCondition Overload built melee weapon, and most especially the TeshinGlaive Orvius as it can suspend an enemy and deal radial damage, which is boosted by the Cyanex's projectiles bouncing between all enemies. While it does not have the benefits of opening enemies up for stealth damage like the Zakti Zakti the Cyanex can effectively apply status to much larger groups and in a shorter period, and thus apply more status procs to a group.


  • The weapon's name is very likely derived from Cyanide, a highly toxic chemical compound.
  • The Cyanex and Komorex 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.
