A bizarre union of Corpus technology and Infested biology, this automatic rifle can also deploy an irradiated airborne infested mass. Further field testing is required to fully understand the potential of this weapon.

The Mutalist Quanta is an Infested fused Quanta with a rapid-fire function in place of the Quanta's continuous fire feature. Like its normal version, the Mutalist Quanta possesses a unique secondary fire feature, in this case projecting infested orbs that increase the damage of shots that fly through them.

Weapon LoadoutsEdit

Alternate FireEdit

  • Shoots a large, Infested orb that travels a short distance, stops, then explodes after 9 seconds. Additional orbs will home in and combine with the first orb, similar to Simulor's orbs.
    • Orbs can be stacked up to 3 times.
    • Launching an orb costs 5 ammo per orb.
    • Shots fired through a single orb will gain up to +~29% damage (without any elemental mods equipped). An orb stacked twice will yield +~190% damage, while three stacks will yield +~271% damage.
      • In general, the damage bonus consists of a reduction of base damage by 1/3 along with +101% / +379% / +510% bonus electricity damage depending on whether the orb has 1 / 2 / 3 stacks. This bonus is applied to each stack of orbs shot through, and maximum damage is typically reached for one orb with three stacks.
    • Shots fired through the orb deal additional Electricity b Electricity damage.
    • Shots fired through the orb will gain additional critical chance, unaffected by mods.
    • Shots fired through the orb will also receive a 25% increase to critical damage. Critical damage mods do not affect orb bonus damage.
  • Enemies standing in the orb receive damage every second.
  • Orbs block enemy fire, such as Bombard rockets, from passing though.
  • Orbs deal Radiation b Radiation damage and have a guaranteed status proc.
  • Orbs bounce off solid objects and can be moved around using melee attacks, allowing the mass to be thrown into multiple enemies after coming to a stop.
  • The more an orb is stacked, the larger an attractive force it will have. For example, if one orb is fired towards an existing orb that has been stacked before, the higher stacked orb will absorb the new orb.
  • Other than projectile weapons, the following things have special interactions with Mutalist Quanta orbs.
View List of special interactions List
  • The Operator's Void Beam and Amps will gain additional Electricity b Electricity damage and critical chance.
  • Fireball will gain Electricity b Electricity damage, which combines to become Radiation b Radiation damage, and the ability to critically hit.
  • Freeze will gain the ability to critically hit as well as a damage bonus, but no Electricity b Electricity damage.
  • Artemis Bow and Dex Pixia will receive a critical chance bonus and additional Electricity b Electricity damage.
  • Antimatter Drop receives the ability to critically hit, as well as bonus damage.
  • The secondary projectiles of Smite will gain the ability to critically hit and bonus Electricity b Electricity damage.
    • This is difficult to do as the enemy must be inside the orb for the secondary projectiles to loop around and go through the orb to hit them.
  • Direct impact from Vauban's grenades will have bonus damage, the ability to critically hit, and a low chance to deal an Electricity b Electricity proc. The abilities themselves are not affected.
  • Gunblades will receive a critical chance bonus and additional Electricity b Electricity damage.
  • Caustacyst's charge attack projectile receives bonus damage and critical chance.
  • Tornado and Exalted Blade's waves are not affected by Mutalist Quanta orbs.
    • Exalted Blade's waves will push the orbs around and will not receive any bonuses.
  • Glaives and Sigma & Octantis' shield can not pass through the bubble.
    • Glaives with Mod TT 20pxPower Throw equipped can pass through the bubble but don't receive any benefits.

  • Requires a fairly large amount of resources, including MutagenMass64 5 Mutagen Masses, NanoSpores64 15,000 Nano Spores, Circuits64 1,200 Circuits, Forma64 1 Forma and Credits6480,000 (including both the blueprint and the cost of construction).
  • While increasing critical damage won't increase the innate critical damage of orb explosions, it will increase the critical damage boost the orbs give.
  • Mirage's Hall Of Mirrors ability creates 4 illusory copies, 2 of which shoot their own weapon copies and can fire their own separate orbs, which are also capable of increasing a weapon's critical chance and damage. Although these orbs will be attracted to the original, they occasionally will not merge with it, effectively allowing the player to receive the damage increase three times. This may even allow the Mutalist Quanta to deal orange critical hits.
  • With both barrels rotating while firing, the weapon can block the player's vision when engaging targets.
  • Explosions from orbs will also deal damage to allies in range


  • The weapon's secondary fire synergizes well with Mirage's Hall of Mirrors as her clones can shoot at least one orb each, for up to three orbs at once.
  • Mod TT 20pxHeavy Caliber seems to have very little effect on the Mutalist Quanta's accuracy, making it a viable option for increasing the weapon's damage output.
  • Placing orbs in corridors or near chokepoints helps maximize the effectiveness of their boost.
  • The innate Vazarin Pol polarity matches Mod TT 20pxPrimed Cryo Rounds.
  • Enemies become confused and attack one another when they touch the orb, making it useful for crowd control.
  • Orbs will immediately explode when impacting Blunts, Bulwarks, Decoys, Molts, and Ramparts, allowing players instantly deal high amounts of damage.
  • While modding for additional critical chance is not recommended as the boost from the orbs does not take mods into account, modding for critical damage is recommended as the orbs allow weapons to critically hit more often and because the critical damage bonus is affected by mods.
  • Orbs can increase the critical chance of weapons to the point where they can deal orange and red crits.
    • Weapons that can attain a critical chance of at least 38% will have the ability to deal orange crits when fired through the orbs.
  • Combining orbs together will not  refresh their duration. Avoid combining orbs if one has been out for a while to conserve ammo.
  • Due to the erratic physics of the orbs and the threat of them being thrown around by allied and enemy melee attacks, it can be difficult to line up an orb 'stack' to effectively shoot through. Consider getting to higher ground and/or letting an ally distract enemies for you to avoid the threat of your orbs being moved away by melee units.


  • Infested orbs will add a critical chance bonus to Zenistar discs and bonus damage to direct disc impacts, but will also lower the AoE damage of the disc, resulting in lower and lower damage despite eventually being able to get red crits.
  • The added electricity damage seems to combine with other single elements on projectile secondaries, but not on continuous or hitscan secondaries.
  • Infested orbs will move in random directions, usually towards the player, when stacking.
  • Orbs fired by Mirage's clones will occasionally not stack with the original orb, despite being attracted to it, which can give the Mutalist Quanta the ability to deal orange crits.
    • Said orbs can however stack and fire off in random directions.
  • In Captura, when slow motion is enabled or the player is in the War Within Choice scene, the Mutalist Quanta's arms will not rotate properly when firing; they will jerk to the side slightly between shots but move back to their neutral position by the time another shot is fired.
  • Since an unknown update, the warped orange 'cube' that once appeared around the infested bubbles no longer renders.


  • The word Mutalist may refer to Mutualism, which is a sector in biology which refers to how two different species interact with each other where each individual benefits. Alternatively, it may simply be derived from mutate.
    • "Muta" is a form of the Latin verb mūtāre, which means "to alter/to change".
  • The word Quanta is plural for Quantum, used in Physics as a measure of the smallest minimum constituent of any object, ex. a Photon is the smallest quantity of light.
  • The weapon has a non-static model; the weapon's arms will rotate when firing and the Infested growth moves at all times as well.
    • The weapon's arms will continuously rotate faster the longer the user holds down the trigger. This doesn't affect the rate of fire, however.
    • While reloading, the Infested growth on top of the weapon will eject the spent energy cell and throw it away while the player inserts a new one.
  • This was the first weapon to repurpose the Zoom key into a separate Alternate Fire key that results in a completely different attack and also the first weapon to possess a separate secondary fire mode that is not engaged via charging.
  • This weapon is the third hybrid weapon in the game, incorporating both Corpus and Infested characteristics, after the Orokin/Grineer Seer and the Infested/Grineer Torid.
  • The weapon's projectiles appear to fire from the infested growth. Since the weapon rotates, the projectiles converge in a spiraling pattern toward the player's crosshair.
  • Oddly enough, the Infestation of the weapon resulted in the arms rotating when firing, normal shots turning into individual energy bursts that deal physical damage instead of electricity and the Quanta cubes being replaced by Infested orbs.
  • The Mutalist Quanta's projectile model is identical to the Paracyst's and Torid's, being a chitinous brown-violet pod with a number of large, yellow, barnacle-like 'tubes' coming from it. This can easily be seen in Captura by pausing the time and zooming in on one of the projectiles.
  • Interestingly, the energy color for both the primary and secondary firing modes is orange and is unaffected by the chosen energy color.
