The Strun can be purchased from the Market for 25,00025,000 .
Using the Shotgun Ammo Mutation mod 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.
Compared to the Boar, the Strun has a tighter bullet 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 bullet cone and a more efficient ammunition economy. Think of the Strun as the middle ground.
The listed damage is actually the total of all the pellets' damage value. The actual damage per pellet is 16.5Impact, 4.5Puncture, and 9Slash.
Before Update 12.0, the weapon's price in the market was 75,00075,000 .
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 quite puzzling given the enormous choke.
Corrupted Crewmen commonly use the Strun in Void missions, except that their versions fire a burst of yellow energy pellets instead of bullets.
The Strun is most likely a Tenno weapon, despite its augmentation the Strun Wraith, a Grineer-focused customization. The Strun bears a faint Tenno marking on it stock as proof. With the addition of the Latron Wraith, the suffix seems to have lost any Grineer focus.
Additionally, the Strun shares many similarities to the Boar, which is a weapon that has received a Prime version, proving it as Orokin technology.
The Strun received a PBR (Physically Based Rendering) update in Update 16.7.
