The Strun is a powerful shotgun that is the successor to the 
MK1-Strun. The Strun bears good damage per shot and decent status chance, capable of killing most light enemies in a single shot.
This weapon can be sold for 
7,500.

Impact damage. - Innate multishot of 12 pellets.

Notes
- Reload time is 0.75s + 0.5s per round, coming to 3.75 total seconds to reload a completely empty mag.

Ammo Stock are used.

- Compared to the
Boar, the Strun has a tighter pellet cone and a much more efficient ammunition economy. The 
Hek has an even smaller base magazine size than the Strun, but bears an even tighter pellet cone and a more efficient ammunition economy. The Strun could be considered the middle ground of the three. - Before Update 12.0 (2014-02-05), the weapon's price in the market was 75,000.
Incarnon Genesis
- Upon completion of The Duviri Paradox and Angels of the Zariman, and unlocking The Steel Path, players can earn
Strun Incarnon Genesis from The Circuit's Steel Path to place on their Strun with the help of Cavalero in the Chrysalith. This Incarnon Genesis form grants it evolutions to a transformation and newfound strength.
Evolution
This section is transcluded from Strun Incarnon Genesis § Evolutions. To change it, please edit the transcluded page.

Blast damage, with much higher Critical Chance, Critical Multiplier, and Status Chance. However, it loses shotgun multishot mechanics and has a base multishot of 1, the Fire Rate is reduced, has much lower base damage, and the explosion possesses Damage Falloff from 100% to 80% from central impact.

Sonar or Detect Vulnerability in places other than actual weakpoints. - Weakpoints on corpses or Invulnerable targets do not build charges.

Tips
- Using Shotgun Ammo Mutation or Vigilante Supplies can help regain ammo when needed, although not as often as the full auto shotguns.
- Weapon's spread cone can be shrunk by zooming in.
Trivia
- The Strun appears to use a tubular magazine, presumably the cylindrical protrusion near the rear above the stock - the Warframe will push this section while reloading.
- Assuming the Warframe is adding shells into this tube, or replacing it, it would imply that the shells used by Strun are extremely small, which is puzzling given the enormous choke.
- When it was originally released, the Strun was magazine-fed, with the small knob on top of the weapon being its magazine. This was changed into the shell-feed system currently in use.
- The regular Grineer Trooper previously used this weapon prior to Update 11.0 (2013-11-20), and currently wield
Sobeks. - Corrupted Crewmen used to wield a Strun in Void missions, except their version fired a burst of yellow energy pellets instead of bullets.
- The Strun shares many similarities to the Boar.
- The Strun received a PBR (Physically Based Rendering) update in Update 16.7 (2015-06-04).

Strun Skins
Patch History
Hotfix 37.0.1 (2024-10-02)
- Fixed the Strun clipping into Koumei when holstered.
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:
- Strun
Update 30.9 (2021-11-11)
- Fixed reloading an extra bullet into the Strun if you fired 5 or more shots before the reload.
Update 27.2 (2020-03-05)
- Greater than 100% Status having meaning:
Shotguns have a unique Role here based on a very patch-work history with how they interact with Status Chance. A Shotgun that shoots 99% Status Chance would give you 35% (roughly) status per pellet. 100% Status Gives you 100% Status per pellet. This huge jump in performance happens with just a 1% gain - why? Well, to answer that we have to look at our choice to make what the UI conveys reality. It would feel broken to shoot a Shotgun with 100% Status and not see a perfect spread of Effects. In reality, to make Status consistent we have to treat Shotguns as a special case.
Shotguns as a special case means we have buffed the Status Chance of all Shotguns by x3 or greater. The UI now behaves to show the reality that you are determining Status Chance per pellet.
- (Undocumented) Status chance per projectile increased from 1.6666666666667% to 5%.
Update 17.0 (2015-07-31)
Several changes have been made to shotgun weapons across the board -- resulting in a list of changes similar from weapon to weapon. The following list of changes apply to all Primary Shotguns with exception to the Phage:
- Increased damage across all shotguns.
- Damage after projectile falloff has been increased for all shotguns.
- Some shotguns have been given improvements to reload speed.
- Some shotguns have received improvements to their projectile speed.
- Death at close to mid range will now toss enemies into a forceful ragdoll.
- (Undocumented) Strun series changed from magazine-based reload to shell-by-shell reload.
Update 7.10 (2013-05-03)
- Effective range increased.
Update 7.x Weapon Balance (2013-03-22)
- Tweaks to Recoil feel and Accuracy, generally sharper Rotation and Translation Springs, added Noise & better spread control when firing while aimed. Added force feedback to all firing sounds.
- Increased damage per pellet from 12 to 14.
- Decreased reload time from 3.37 to 3.
- Increased Crit Chance from 5% to 7.5%
