Designed to quickly vaporize minerals for content analysis, users discovered its powerful beam was equally efficient at dispatching hostiles.

The Gammacor is a Cephalon designed wrist-mounted laser that deals DmgMagneticSmall64.png Magnetic damage, making it ideal for tackling the Corpus. Although it is pinpoint accurate and relatively quiet, its limited range means that players will have to close the distance to get the most out of this weapon.

The Gammacor is a requisite ingredient for the Heliocor.png Heliocor.


  • This weapon deals DmgMagneticSmall64.png Magnetic damage.
  • Damage ramps up from 25% to 100% over 0.6 seconds when firing. After firing stops for 0.8 seconds, the damage decays back to 25% over 2 seconds.
  • Comes with a Vazarin Pol.svg polarity.


  • Pinpoint accuracy.
  • Reduced Noise Level.
  • Consumes 0.5 ammo per tick of damage.
  • Normal Attack
    • High magazine
    • High effective fire rate
    • Above average max ammo
    • Above average reload speed


  • Limited range of 25 meters.
  • Normal Attack
    • Low crit chance
    • Very low damage
    • Low disposition
    • Below average crit multiplier



The Gammacor's blueprint can be purchased from the Market. Alternatively, it can be acquired from completing the Uranus to Neptune Junction.

  • The 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.


  • Mod TT 20px.png Ruinous Extension can aid in extending the short range of this weapon.
  • As the Gammacor already deals DmgMagneticSmall64.png Magnetic innately, 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 Gammacor highly effective against Corpus proxies like MOAs that possess both Shields and Robotic hit points. The 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.
    • Alternately, the Gammacor can be fitted with DmgCorrosiveSmall64.png Corrosive damage for anti-Grineer. With shield and armor degradation status effects, such a Gammacor would be extremely effective against both Grineer and Corpus bosses.
  • The innate Vazarin Pol.svg polarity can somewhat limit elemental modding potential, thus making it a less desirable polarity for elemental modding. 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.


  • Unlike most secondary weapons, the Gammacor is worn like a gauntlet on the Warframe's right arm.
    • However, Warframes will still extend their right index finger as if they're holding a single pistol. Idle animations will also play as though the Gammacor is a single pistol.
  • This is the second weapon (along with its Synoid variant) released that has an innate DmgMagneticSmall64.png Magnetic damage (with the first being the Velocitus.png Velocitus), but is the first to ever be used for general gameplay, as opposed to being limited to Archwing missions.
  • The metallic structure (the primary part on the color setting) has a purplish tint.
  • The circular holograms expand as the weapon is being fired.
  • The weapon's design suggests that it may have originally been a device created by Cephalon Simaris, due to its aesthetic similarities to other devices in his employ like the Synthesis Scanner, which appears to use the same parts.
    • This is furthered by the fact that the Codex states that it was "Designed to quickly vaporize minerals for content analysis."
