Shifty is a basic training perk featured in Call of Duty: WWII.
Overview
Shifty grants players 2 additional attachments to their sidearms, similar to the cut Primed basic training. As an added bonus, it will also give the player unlimited pistol ammo, and a replenished magazine of ammo if the player switches the sidearm with their primary weapon and back.
On May 31st 2018 , the basic training was buffed , giving players 2 additional attachments (from 1 additional attachment), giving players 3 overall attachments ( 4 with the Infantry Division), as Sledgehammer Games cited that Shifty was on the low end of basic training usage , and adding a second pistol attachment would make pistols more viable outside of the Infantry Division.
