The Siren is a Special weapon added to Black Ops 7 and Warzone in the Season 3 Reloaded update (April 30, 2026). Its in-game description reads "Charge energy weapon. Fires a high damage, slow moving projectile that passes through foes. Charge to improve projectile velocity." With its Prestige attachment (the MFS Deflection Core) equipped, projectiles travel faster, ricochet off surfaces and enemies, and gain increased ammo capacity; in Zombies it becomes the Gaze of Circe when upgraded via Pack-a-Punch.

A charge-based energy special weapon whose slow projectiles pierce through multiple enemies, rewarding charged shots for higher velocity and (with its Prestige attachment) ricochet.

How to unlock: Sits on the free reward track of the RoboCop Event Pass; reportedly requires earning roughly 460,000 XP across any Black Ops 7 / Warzone game mode to reach it.

Siren camo challenges

Military camos follow a class-wide ladder; the three Special camos are unique to the Siren. Finish all 12 in a mode and its four Mastery camos unlock in order.
