Kills with the 'Luison' do not count towards any pistol challenges in the Weekly Challenge System, only gadget challenges.

The PRB92 is intended to represent the Taurus PT92, a Brazilian copy of the Beretta 92.Non-lethal damage which assists interrogation.As a close-range focused weapon, the 'Luison's' damage dropoff is extremely poor and its recoil leaves something to be desired since the custom Suppressor already takes up the Barrel Attachment. With a powerful 64 damage per shot, the ВЁLuisonВЁ can take down any armor type in just 2 shots within optimum range. However, firing at an Operator already in a DBNO state will kill them. Described as being non-lethal, the 'Luison' will always down Operators instead of killing them (unless they are the last Operator on the enemy team), allowing Caveira to enact her interrogation ability. It is designed as a powerful close-range pistol. The Luison is Caveira's pistol, featuring a smaller magazine capacity and customized Suppressor and subsonic rounds. The Luison is a unique variant of the PRB92 introduced in the Operation Skull Rain expansion. High knock-down power in close-quarter, but is non-lethal.'
