The Synoid Gammacor can be acquired by reaching the Rank of Genius with Cephalon Suda, and spending 100,000100,000 to purchase. As with all Syndicate Weapons, the Synoid Gammacor cannot be chosen as the free offering upon ranking up to Genius rank.
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 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.
The Synoid Gammacor has an innate Entropy effect identical to that found in Cephalon SudaWeapon Augment Mods. Upon accumulating sufficient affinity, the Synoid Gammacor will release an AoE radial blast that deals Magnetic damage and proc, restores 25% of the Warframe's base Energy, and temporarily buffs maximum Energy by 25% for 30 seconds. Caster frames with high energy pools will benefit most from this effect, while lower energy count frames will not get very much energy with the bonus.
As the Synoid Gammacor already innately deals Magnetic damage, it can accept other combination elemental damage types that use Electricity or Cold damage as a base. In particular, adding 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 Viral damage to make it highly effective against organic Corpus like Crewmen which posses both Shields and Flesh hit points.
The innate 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.
Aiming the Synoid Gammacor's beam through Volt's 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 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.
The Synoid Gammacor was the first item in the game to have the "Synoid" prefix, followed by the Synoid Syandana in second.
