Exclusive Guide: Unlocking the X52 Resonator and All Echoes of the Dead Event Rewards in BO6 and Warzone

The highly-anticipated “Echoes of the Dead” event has plunged Call of Duty: Black Ops 6 (BO6) and Warzone into a chilling, time-limited battle against vengeful spirits, offering players the chance to secure exclusive high-value rewards. Headlining the event rewards is the X52 Resonator Special Weapon, a devastating energy-based firearm that is rapidly shifting the meta across all modes. This comprehensive, SEO-optimized guide breaks down the critical steps, challenges, and high-CPC keywords to ensure you secure this powerful weapon and every other item before the event concludes on October 23, 2025.

As part of The Haunting Season 06 update, the “Echoes of the Dead” event is a major draw for players seeking exclusive in-game content and a competitive edge. The good news for players juggling different preferences is that Activision has structured the challenges to be flexible. For each of the eight core rewards, you only need to complete one challenge from the three available modes: Multiplayer (MP), Zombies (ZM) in the Haunted Havoc mode, or Warzone (WZ) in the Zombie Royale mode. This structure maximizes player participation and ensures that all core fan bases can easily boost their accounts.

X52 Resonator Special Weapon and Core Rewards

The X52 Resonator is a unique special weapon that introduces modular crystal shards for varied attack patterns—a true game-changer in high-tier engagements. Completing all challenges also rewards the Animated “Toxic Metal” Weapon Camo, a prestigious cosmetic signaling mastery of the event. BlackCell subscribers receive an additional, exclusive variant.

Echoes of the Dead: Full Challenge Breakdown

The following is the complete list of all eight unlockable rewards and the corresponding challenges. Focus on the mode that offers the most efficient XP farming and fastest progression for you.

• Reward 1: “Cool Helm” Weapon Charm
  • MP: Get 150 Eliminations.
  • ZM: Eliminate 500 zombies in Haunted Havoc mode.
  • WZ: Get 25 Eliminations in Zombies Royale mode.

  Tip: The Multiplayer elimination challenge is often the most straightforward route, especially in high-intensity playlists like Shipment 24/7 or Hardpoint, offering a quick unlock path.

• Reward 2: Double XP Token (1 Hour)
  • MP: Finish any match with a Top-Three Score.
  • ZM: Eliminate 10 Mimics in Haunted Havoc.
  • WZ: Get two eliminations without reloading.

  Tip: The Warzone “two eliminations without reloading” is exceptionally easy with a Shotgun or a high-capacity Light Machine Gun (LMG), making this a high-speed unlock for premium users.

• Reward 3: GPMG-7 Muzzle Booster Attachment

  This powerful new attachment enhances the GPMG-7 LMG’s bullet velocity and rate of fire, sacrificing only minor recoil control—a crucial addition to the LMG meta.

  • MP: Get 50 Eliminations with LMGs.
  • ZM: Get 300 zombie eliminations with LMGs.
  • WZ: Get 5 Eliminations with LMGs.

  Tip: For a rapid unlock, the Warzone challenge is highly efficient. In Zombie Royale, dropping into a hot zone with an LMG setup can yield this in a single match. LMG dominance is essential here.

• Reward 4: “Blast Burn” Calling Card
  • MP: Earn 20,000 total Score.
  • ZM: Earn 50,000 total Essence in Haunted Havoc.
  • WZ: Open 25 Loot Caches in Zombie Royale.

  Tip: Zombies players should prioritize Essence farming in Haunted Havoc to complete this passively while grinding the other zombie-related challenges. WZ players focusing on loot cache acquisition will also clear this quickly.

• Reward 5: Double Weapon XP Token (1 Hour)
  • MP: Get 10 Kills with Lethal Equipment.
  • ZM: Kill 10 or more zombies with a single Scorestreak three times.
  • WZ: Get a Kill with Lethal Equipment.

  Tip: The Warzone challenge—a single kill with lethal equipment—is the fastest method. A well-placed Frag Grenade or Semtex at the start of a match will immediately secure this valuable Weapon XP boost.

• Reward 6: Large Decal
  • MP: Earn five Double Kill medals (Two rapid kills) or better.
  • ZM: Earn five Massacre medals (10 rapid kills).
  • WZ: Get three or more Eliminations in a match two times.

  Tip: The Multiplayer Double Kill challenge is easiest in objective modes like Domination or Patrol. For Zombies, using explosive weaponry or a high-fire-rate weapon to get the Massacre medals is a reliable strategy for cosmetic unlocks.

• Reward 7: “Arty Incineration” Finishing Move
  • MP: Get 10 Kills using Melee Weapons.
  • ZM: Get 30 zombie Kills with Melee Weapons.
  • WZ: Complete a Bounty contract.

  Tip: Focus on Warzone’s Bounty contract for the fastest completion. Melee kills can be a fun but slower grind. Securing this Finishing Move adds a high-tier cosmetic to your Operator Bundles.

• Reward 8: X52 Resonator Special Weapon

  The ultimate prize of the event, this weapon is unlocked upon clearing the final challenge slot. Once unlocked, you can also customize it with three unique Shard crystal attachments for varied tactical use.

  • MP: Get five Top 3 Finishes.
  • ZM: Earn 10,000 Total Score in Haunted Havoc on five separate days.
  • WZ: Exfil in Plunder with over $250,000.

  Tip: The Warzone Plunder Exfil challenge is, arguably, the most controlled path to securing the X52 Resonator. Focus on high-value contracts and secure your cash. The Multiplayer Top 3 finish can be quick, especially in smaller party modes, but is highly dependent on team performance. This weapon is a top-tier competitive advantage and is central to the current BO6 weapon meta.

CPC High-Value Keywords and Strategic Unlocking

To maximize your return on the grind, remember that the “Echoes of the Dead” event runs for a limited time. Strategic players will focus on high-efficiency challenges in their preferred mode to secure the X52 Resonator unlock and the GPMG-7 Muzzle Booster first, as these offer a direct competitive advantage and are high-value CPC keywords.

Time is running out, so optimize your grind today!
