How to unlock the Siren special weapon in BO7 and Warzone
The Siren is available through the Call of Duty x RoboCop Event Pass, and the good news is you don’t need to spend anything to get it since it sits on the free reward track. To unlock it, you simply need to play matches across Multiplayer, Zombies, Endgame, or Warzone and earn XP to progress through the event tiers.

As you climb through the pass, you’ll eventually reach the required milestone to claim the weapon. Based on early details from the Season 3 Reloaded update, the Siren appears to be the final reward on the free track, which means you’ll need to rack up a significant amount of XP before unlocking it. The exact requirement should become clearer once the event goes live.
If you’re not interested in grinding through the event, you can purchase it straight away. The Siren has a blueprint called “Recognition Hamper” in the Tracer Pack: Cyberfall Ultra Skin Bundle. While Activision hasn’t confirmed the exact price yet, Ultra bundles usually cost around 2,400 CoD Points or more.
The Siren fires a high-damage projectile that moves slowly but can pass through multiple enemies, making it effective in clustered fights. The weapon features a charge mechanic, where holding the trigger increases the projectile’s velocity, allowing for more consistent hits at longer distances.

This special weapon includes rear grip options that let you adjust the weapon toward either better mobility or improved handling. Its Prestige magazine attachment, the MFS Deflection Core, remarkably changes how the weapon performs. With this attachment equipped, projectiles travel faster, ricochet off surfaces and enemies, and come with increased ammo capacity, enabling aggressive play.
All Siren Prestige Camos in BO7 & Warzone
If you’re planning to fully level up the Siren, you’ll unlock these distinct Prestige camos through Weapon Prestige progression:

- Prestige 1: Racer
- Prestige 2: Dionaea
- Prestige Max: It’s Corn
All Weapon Prestige Camos are universal, meaning once unlocked, you can apply them to other weapons in your arsenal as well. While the Siren doesn’t feature animated Prestige camos, the designs still offer a solid visual upgrade as you progress.
