Deployed by the Cephalon Suda, once a data-analyzing instrument, the Gammacor's main focus is defense.

The Synoid Gammacor is an exclusive version of the Gammacor.png Gammacor available only from Cephalon Suda, possessing better stats as well as innate Entropy effect.


This weapon deals DmgMagneticSmall64.png Magnetic damage.



  • Innate DmgMagneticSmall64.png Magnetic damage – less effective against Alloy Armor.
  • Damage ramps up from 30% to 100% over 0.6 seconds when firing. After firing stops for 0.8 seconds, the damage decays back to 30% over 2 seconds.
  • Limited range of 40 meters.



  • The Synoid Gammacor can be acquired by reaching the Rank of Genius with Cephalon Suda, and spending ReputationBlackx64.png 100,000 to purchase. As with all Syndicate Weapons, the Synoid Gammacor cannot be chosen as the free offering upon ranking up to Genius rank.
  • Syndicate weapons can be also be acquired via Trading, but only for unranked copies without Forma and Orokin Catalyst installed.
  • Players must have a Mastery Rank of at least 7 to acquire the Synoid Gammacor, either through trading or through the Syndicates themselves.


  • The Synoid Gammacor's beam when fired does not immediately hit at its maximum range. Instead it takes around half a second to extend to its maximum range, and will maintain that range as long as the weapon is being fired. The beam retracts when the weapon stops firing.
  • Throwing VaubanIcon272.png Vauban's trapping modules while aiming with the Synoid Gammacor will result in the modules being thrown a little to the left of where they would be thrown with other weapons. Aiming to the right of the target can compensate for this discrepancy.


  • Mod TT 20px.png Ruinous Extension can aid in extending the short range of this weapon.
  • As the Synoid Gammacor already innately deals DmgMagneticSmall64.png Magnetic damage, it can accept other combination elemental damage types that use DmgElectricitySmall64.png Electricity or DmgColdSmall64.png Cold damage as a base. In particular, adding DmgRadiationSmall64.png Radiation damage makes the Synoid Gammacor highly effective against Corpus proxies like MOAs that possess both Shields and Robotic hit points. The Synoid Gammacor can also be equipped with DmgViralSmall64.png Viral damage to make it highly effective against organic Corpus like Crewmen which posses both Shields and Flesh hit points.
  • The innate Vazarin Pol.svg polarity can somewhat limit elemental modding potential if Mod TT 20px.png Galvanized Shot is not available, thus making it a less desirable polarity. If you wish to focus more on elemental damage, then it is recommended to either ignore the polarity or use Forma to turn it into a more suitable polarity.
  • Aiming the Synoid Gammacor's beam through VoltIcon272.png Volt's ElectricShield130xDark.png Electric Shield will increase the beam's range while still having the advantages of hit-scan and pinpoint accuracy
    • However, when aiming the beam through the shield it can be a bit harder to aim at targets from a distance due to the shining light of the beam on contact of any surface (in this case: the Electric Shield).
    • Shooting through the Electric Shield will give the weapon additional DmgElectricitySmall64.png Electricity damage.


  • Unlike most secondary weapons, the Synoid Gammacor is worn like a gauntlet on the Warframe's right arm.
  • The Synoid version replaces the circular holograms formed on the arm with the Cephalon Suda emblem.
  • The word 'Synoid' is likely a corruption of the word 'synod', which is an assembly of the clergy under a church, or a reference to the word 'synapse', a biological term defining the gap between two neurons. It could also be a deformation of the word sinusoid which is a form of wave used for electrical measurements, since the weapon deals magnetic damage, it would most likely be related to this original term.
  • The Synoid Gammacor was the first item in the game to have the "Synoid" prefix, followed by the Synoid Syandana in second.


  • Equipping an Extinguished Dragon Key will cause the arsenal UI to display values based on the Gammacor.png Gammacor's damage.
