This particle cannon generates a condensed beam of super-heated plasma designed to melt rock to ore, and enemies to molten slag.

The Atomos is a Grineer particle cannon, firing a DmgFireSmall64 Heat-based beam that can chain between multiple enemies.

This weapon can be sold for Credits64 2,500; it is also a requisite ingredient for TwinBasolk Twin Basolk.

Notes[]

  • When fired at an enemy, the beam will chain to the closest living enemy within 7 meters of the initial target. From there it will chain again, up to a maximum of 3 chains in total. A chain will do 0.75n times the main beam's damage, where n is the chain number. Any enemy caught in the width of the beam will also be damaged. It has a small radius of damage around the beam, similar to the Ignis Ignis and Embolist Embolist.
    • The damages are : 100% for the main target, 75% for the first in the chain, 56.25% for the 2nd, and 42.1875% for the 3rd.
    • Headshotting the original target does not affect the chain damage.
    • The beam will not chain to a Nullifier through its shield should it connect with a target outside or partially enclosed by it.
    • The beam can also continue to chain to enemies even if targeting a dead enemy or an enemy who is dead but in a dying animation.
  • The Atomos' innate DmgFireSmall64 Heat element is positioned last when adding elemental damage mods to the weapon.
    • Because of this Heat property and ability to chain, the Atomos is functionally similar to the Corpus TenetCycron Tenet Cycron.
  • The Atomos covers up part of the reticle when aiming. This combined with the beams behavior of slowly rotating around a central point means that occasionally the beam will fire behind the weapon with no way of knowing if you are aiming at the enemy or not.
  • Punch Through will cause the main beam to chain independently from each additional target hit, potentially doubling or tripling the total damage output when fired into a crowd. The chain from the target hit after the Punch Through can deal damage to the first target, and vice versa.

Incarnon Genesis[]

Evolution[]

  • Installing the Atomos Incarnon Genesis requires 20 PathosClamp Pathos Clamps, 70 YaoShrub Yao Shrubs and 80 Lamentus Lamentus.
  • When installed, the first Evolution tier is unlocked. The following Evolution tiers, their requirements for unlocking them, and their related perks, are shown below;

Evolution I[]

  • Headshots charge Incarnon Transmutation; Alt Fire transmutes. Switching back will expend any remaining charge.
  • Fire high-powered grenades.
    • Incarnon Form becomes a semi-automatic grenade launcher whose projectiles explode in a 7.9 meter radius dealing DmgImpactSmall64 Impact damage on direct hits and DmgBlastSmall64 Blast damage on the explosion, with significantly higher base damage, Critical Chance, Critical Multiplier, and Status Chance. However it has significantly slower Fire Rate, the explosion possesses linear Damage Falloff from 100% to 20% from central impact, and the projectile has travel time with arcing.
  • Mode switching is not instantaneous and has an animation equal to the weapon's reload speed.
  • Incarnon Form is activated by filling the Incarnon Transmutation gauge that appears under the reticule by achieving headshots and then pressing the Alternate Fire button. 21 headshots will completely fill the gauge. A full gauge is not required to activate Incarnon Form.
    • Charges generate only on headshots, and not other weakspots, such as the backpacks of most MOA variants. Similarly, shooting weakspots generated by either Sonar130xWhite Sonar or Mod TT 20px Detect Vulnerability in places other than heads will have no effect either.
    • Headshots on corpses do not build charges.
    • Individual Multishot bullets can build charges.
  • Instead of drawing ammunition from its reserves, the Atmos's Incarnon Form uses a separate "magazine" with each charge producing 1 round to a maximum of 21. Once all ammunition is expended, the Atmos reverts to its normal form.
    • Incarnon Form's magazine is not affected by mods.
    • Incarnon Form is not affected by Ammo Efficiency (such as EnergizedMunitions130xWhite Energized Munitions).
    • Charges and Incarnon Form persists through all activities, such as holstering, bleedout, or being disarmed. However, charges and Incarnon Form are removed upon death.
  • Swapping to and from Incarnon Form will fully reload the normal form's magazine.

      • This is on personal shield break, not breaking enemy shields.

  • Perk 1: Moonrise Velocity:
    • +7 Range.
  • Perk 2: Mercenary Chamber:

    • Increase Status Chance by +10%.

Tips[]

  • Mod TT 20px Ruinous Extension can be used to extend this weapon's reach, allowing it to hit targets further away.

Trivia[]

  • Atomos is the Greek word for "undivided", and is the origin of the word Atom, referring to the smallest constituents of physical matter identifiable as a chemical element.
  • Anastomosis is a Greek word meaning the reconnecting of various streams, such as in blood vessels or river deltas.
  • As of the release of Atomos, it is now possible to have a loadout consisting of purely DmgFireSmall64 Heat damage, combined with Ignis Ignis, Silva&Aegis Silva & Aegis (Prime) orTwinBasolk Twin Basolk, and ChromaIcon272 Chroma (Prime) (with the appropriate energy color) or EmberIcon272 Ember (Prime).
    • Before the release of Atomos, the closest one could get to this effect was with using a Tysis Tysis that was heavily modified for DmgFireSmall64 Heat and Status Chance.
  • Ground-based enemies (e.g. Corpus Crewmen, Infested Chargers etc.) slain by the Atomos will char or appear to be coated in ash, and then disintegrate. Like the Glaxion Glaxion's special effects, this effect occurs even if the Atomos is modified to deal a different kind of damage.
  • When reloading, two sections are removed and subsequently replaced individually, unlike other weapons. It can be speculated that one could be fuel and the other an igniting agent or propellant.

Bugs[]

  • The Atomos's visual effects will not go through VoltIcon272 Volt's ElectricShield130xWhite Electric Shield, but it will interact with the shield normally (critical damage bonus, range boost, etc.)
  • If a Tenno is currently firing the Atomos when they are revived from the downed state, the visual and audio effects of the beam may become stuck at that position and randomly target enemies or even fellow allies for the remainder of the mission. (If stuck to a Tenno it will follow them all the way to extraction, resulting in further eyesore as it clips through the entire map and all terrain to do so.)
    • However the bugged beam does no damage and is purely an aesthetic issue.
  • Sometimes if you reload the magazine for the Atomos, it will not attach to the gun but it will have a full magazine. Just reload the gun to fix this as this does not affect the gun's use.

Update 32.0 (2022-09-07)

Ammo Changes

We understand the power fantasy of these weapons is very popular for some, so our first approach was to keep them powerful, but limit how often they can be used by making changes to ammo pick-up.

Ammo Pickup Overrides
The following weapons now have ammo pickup overrides, meaning they gain less from picking up ammo. This mostly applies to AoE weapons, in hopes that players will become more deliberate with their aim to make the most of their Ammo pools. The following lists the specific ammo pick up overrides per weapon category.
