Stagger targets with blasts from this Corpus engineered plasma shotgun. Surviving enemies are consumed with radiation.
The Arca Plasmor is a 
Corpus-built plasma shotgun that fires highly damaging pulses of 
Radiation with a guaranteed 
Impact proc. The projectiles it fires are wide and have infinite Punch Through on bodies, making it highly effective in mowing down large groups of enemies, but suffers from a low critical multiplier and no bonus damage on headshots.

Notes[]
Known Bugs[]
Galvanized Savvy is multiplicative to base damage sources on direct hits.
Tips[]
- Due to its innate body punch-through, the Plasmor is of great use in Arbitrations, easily passing through shielded enemies to get to shield drones.
- Because the range and damage falloff are determined by the weapon's Projectile Speed, adding in Fatal Acceleration will increase the range and falloff limits by 40%, to 14m minimum falloff and 28m maximum falloff as well as increasing the range to 42m.
- Due to its innate
Radiation damage, the weapon can use elementals and dual elementals that use 
Heat or 
Electricity damage, such as 
Corrosive VS Grineer or 
Magnetic VS Corpus. - Short corridors favor this weapon highly, as a few pulses are normally enough to make short work of enemy clusters as long as no Arctic Eximus or Nullifier Crewmen are present, and the added Impact and Radiation procs will keep enemies at bay.
- The description of surviving enemies being "consumed by radiation" simply means that their bodies will disintegrate on death. While this is undesirable for a Nekros's
Desecrate, it is good for stealth if silenced since there will be no corpses to alert enemies. - It is exceedingly easy to perform headshots with this weapon. Although it has 1x headshot multiplier (meaning it does no extra damage), this can be increased using
Primary Deadhead.
Trivia[]
- The magazine for the weapon is a metal cylinder, which rotates clockwise after firing each shot and pumping the mechanism. No shells are ejected with each pump, perhaps implying the cylinder is filled with batteries or charge cells, which are depleted from a single pump and must be rotated to bring a new cell into position.
- Writings on the side of the weapon seem to translate as "G.S.1.1", and possibly "DANGER EXTREME HEAT".

Patch History[]
Hotfix 32.0.7 (2022-09-28)
- Fixed the following weapons not correctly playing their intended animations between shots:
- Arca Plasmor - Fixed the gun parts moving but not your Warframe.
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.
Primary Weapon Ammo Pick Up Overrides
15 Ammo per Pick Up:
- Arca Plasmor
Many weapons have also had their maximum ammo capacity adjusted.
Primary Weapons:
- Arca Plasmor: From 48 to 50
Update 30.9 (2021-11-11)
- Fixed shooting yourself with the Arca Plasmor when first firing it after you’ve been Revived.
Update 25.8 (2019-10-01)
- October 2019 Riven Disposition Change
- Arca Plasmor: 0.6->0.55
Hotfix 25.7.5 (2019-09-09)
- Fixed Arca Plasmor not being able to damage the Ropalolyst Synovia.
Update 25.7 (2019-08-29)
- Reduced the light intensity of the Arca Plasmor.
Hotfix 25.0.3 (2019-05-24)
- Fixed an issue that made Arca Plasmor, Fulmin and Catchmoon projectiles deal damage twice on the hit when the projectile is destroyed. This was not a case of ‘always worked this way’ as it was accidentally introduced by the Jovian Concord.
Update 24.6 (2019-04-04)
- Improved the left hand position for Arca Plasmor.
Update 24.0 (2018-11-08)
The previous Mainline update of Chimera 23.10.0 included a sneaky bug that removed falloff damage from the Arca Plasmor. The Arsenal continued to state the always present falloff (10.0 - 20.0) but it wasn’t truly applying. We have fixed this bug, which resulted in adding falloff damage back to the Arca Plasmor, and thus returned it to its original falloff state prior to Update 23.10.0. This also fixes the Conclave Arsenal displaying the incorrect falloff damage for the Arca Plasmor.
Hotfix 23.10.3 (2018-10-15)
- Fixed the Arca Plasmor's projectiles bouncing off walls instead of exploding on impact.
Update 23.10 (2018-10-12)
- Updated weapon FX for the Arca Plasmor, Castanas, and Sancti Castanas.
- Fixed certain wave projectiles (e.g. Arca Plasmor) bouncing off hit proxy shields (e.g. Volt’s Electric Shield, Gara’s Mass Vitrify).
- (Undocumented) Projectile now bounces off walls.
Update 22.14 (2018-03-01)
- Tweaked force feedback sound of the Arca Plasmor.
Update 22.12 (2018-02-09)
- Mag size increased from 6 to 10.
Hotfix 22.10.3 (2018-01-29)
- Fixed the Arca Plasmor dealing 0 damage on headshots.
Update 22.10 (2018-01-25)
- Headshots no longer deal bonus damage.
- The Arca Plasmor was designed to hit multiple targets with a high-status chance, but with wide wave projectiles and inherent punch-through, a single shot could result in multiple headshots. With it being a shotgun, it was never intended to behave as a precision weapon, and the bonus pushed it too far out of that mold.
- Headshots should still deal damage (without the multiplier).
Update 21.7 (2017-09-09)
- Introduced.
