  • Targeting Subsystem12?cb=20190608095452 Targeting Subsystem can help negate the accuracy penalty from this mod once its effects activate, down to a 25% reduction of accuracy when combined with a fully-ranked Magnum Force. Keep in mind however that the accuracy bonus from Targeting Subsystem will only take effect once you hit an enemy and will only apply when you're aiming.
  • If a pistol already has a max rank Hornet Strike12?cb=20190608095452 Hornet Strike, adding a max rank Magnum Force represents only a ~163.9175% increase in damage per shot, compared to a 90% increase for a max rank uncommon elemental mod such as Heated Charge12?cb=20190608095452 Heated Charge.
  • However, the AngstrumCorpusHandRocket.png Angstrum can benefit from this, as it allows its charged shots to cover a larger area at the cost of limiting long-range capabilities. Alongside it are other secondaries such as ZaktiZakti.png Zakti, TalonsU18throwingknives.png Talons, CastanasTaserStar.png Castanas, StaticorCrpElectroMag.png Staticor, StugGrineerCrossbowGooGun.png Stug, SonicorCrpAirPistolArray.png Sonicor, PoxInfProximityStars.png Pox, and KulstarGrnTorpedoPistol.png Kulstar when equipped with Multishot mods.
  • This mod also fixes the inaccuracy bug that occurs when using multishot on the CastanasTaserStar.png Castanas and Sancti CastanasNLCastanas.png Sancti Castanas at low level, but it's still advised to max the mod anyway for extra damage and higher spread on the Castanas, leading to more crowd control.
  • This should only be used on weapons that already have Hornet Strike12?cb=20190608095452 Hornet Strike installed, as the bonuses gained from this mod are greater than Magnum Force and comes with no accuracy penalty. Also take Augur Pact12?cb=20190608095452 Augur Pact into consideration as it costs less mod capacity without the accuracy penalty.


  • When it was first released, Magnum Force increased recoil as well as damage. However the recoil penalty did not affect recoil-less weapons (AcridAcrid2.png Acrid, and EmbolistInfestedPistol.png Embolist, among others). This was confirmed to be unintentional in Warframe Prime Time - Episode 2 (9:40). The mod's effects were changed in Update 10.4 (2013-10-16) to give weapons an accuracy penalty instead of a recoil penalty.
  • "Magnum Force" is the name of the second movie in the "Dirty Harry" series of films starring Clint Eastwood.
  • Prior to Hotfix 24.2.10 (2019-01-23), Magnum Force provided +66% damage and -33% accuracy at max rank.
