Our Rezi 12 build improves the shotgun’s one-shot potential at a decent range. The EXP Firelite 12 extends its effective damage range to around 15 meters while keeping your shots suppressed and controlled in ADS.

To offset the barrel’s impact on ADS speed and improve sprint-to-fire speed, we use the Schlager Visiv-5 and No Stock. These attachments help you aim faster and react quickly when enemies appear. The Mire-50 Tac Grip and SA B40 Grip improve recoil control and reduce gun kick, making follow-up shots easier to manage.

For the Rezi 12 class setup, I highly recommend using the Ghost, Ninja, and Battle Hardened perks. Ghost keeps you off enemy detection systems, while Ninja muffles your footsteps, making it easier to flank opponents and close the distance. Battle Hardened provides resistance to enemy tactical equipment, helping you stay aggressive during pushes.

Use Stim to recover during gunfights, and Throwing Knife for quick kills. Seeker Drone allows you to spot a nearby target. UAV and Counter-UAV help reveal enemy positions and disrupt their awareness, while your third Killstreak can be based on your playstyle.
