Black Ops 6 & Warzone: How to Unlock the X52 Resonator in the Echoes of the Dead Event

The Echoes of the Dead event has officially launched in Call of Duty: Black Ops 6 and Warzone, marking one of the most content-packed updates of the year. While Black Ops 7 is already on the horizon, Treyarch isn’t slowing down — Season 6 is ending with a bang.

Between the ongoing Haunting Halloween crossover and several new weapon drops, the event’s biggest highlight is without question the X52 Resonator, a wild new special weapon that fuses sci-fi design with brutal firepower. Here’s a full breakdown of the event, how it works, and every reward you can earn.

🗓️ Echoes of the Dead Event Dates

• Start: Thursday, October 16, 2025 (10 AM PT / 1 PM ET / 6 PM BST)

• End: Thursday, October 23, 2025

The event runs for one full week, giving players time to complete challenges across Black Ops 6, Warzone, and Zombies.

⚙️ How the Event Works

The Echoes of the Dead event introduces a set of multi-mode challenges, with each reward tied to three possible objectives — one for each game mode.

🔮 About the X52 Resonator

The X52 Resonator is a unique, full-auto special weapon with exceptional range and a modular design that allows players to customize its attack style.

Equipping one of three “Shard Attachments” completely changes its firing behavior:
- Orbed Eruption Shard: Versatile multi-shot blast.
- Spiked Barrage Shard: Slow but deadly 7-round burst.
- Stone Escalation Shard: Powerful charged single shot.

This makes the Resonator one of the most versatile and fun-to-use weapons introduced in Black Ops 6.

🧟 Final Thoughts

The Echoes of the Dead event is the perfect way to close out Black Ops 6’s final season — combining spooky Halloween energy with rewarding challenges and a game-changing new weapon. Whether you’re clearing out hordes in Zombies, dropping into Warzone, or grinding multiplayer playlists, there’s something here for every type of player.

Don’t forget — you only have until October 23 to claim the X52 Resonator and the rest of the limited-time rewards before they vanish for good.
