If you’ve spent hours playing Zombie Army 4: Dead War, you know weapon mastery is part of the endgame grind that unlocks skins, boosts, and achievements/achievements.
The Shotgun Pistol, in particular, is one of the DLC sidearms that players either love for its raw chaos or dread because of its quirky mastery requirement.
Fortunately, increasing its mastery shouldn’t be that hard. Here’s a guide to help you with that.
Master Shotgun Pistol Guide in Zombie Army 4

The actual mastery requirement for the Shotgun Pistol is one of the more awkward ones.
For starters, you must get 100 dismemberment kills while scoring kills at timed intervals. Also, hits must count within a set short window.
As such, it’s not mere kill counting like a sniper rifle or pistol headshots. Instead, it’s more on consistent dismemberment and keeping the timing rolling.
The timing aspect is commonly described as needing kills roughly every few seconds so the challenge counter stays active.

So, what are the best methods for increasing Shotgun Pistol mastery?
For starters, playing on easier difficulties with higher enemy counts can help stack dismemberment kills quickly without dying constantly.
You can also use bait grenades to herd crowds into explosive barrels and then detonating them while nearby helps rack up dismemberments fast.
The key is making sure the kills register within the required timing window so the game counts toward mastery.
One way I’d recommend is through Hitler’s Welcome Party (Chapter 4) in All Roads Lead to Hell. First, use a bait grenade to lure the zombies to a common right barrel and kill them in one explosion.
You’ll need luck at your side though when piling up the Nazi zombies to get enough kills. It’s also important to not get yourself killed before the mastery icon shows up.

Once mastered, the Shotgun Pistol gives you the associated cosmetic and the weapon’s mastery bonus.
Weapon mastery in Zombie Army 4 also contributes toward achievements/trophies like “Weapons Expert” or the tougher multi-weapon masters needed for the “I can do anything I want, I got guns!” award.
Also, it’s worth noting that all weapons need 12 upgrades before you can even attempt mastery.
