Call of Duty’s Halloween-themed The Haunting event introduces spine-chilling content to Black Ops 6 and Warzone, featuring the Echoes of the Dead challenge series. This limited-time opportunity allows dedicated players to earn exclusive gear including the formidable X52 Resonator energy weapon, GPMG-7 Muzzle Booster attachment, and multiple cosmetic enhancements. Our comprehensive breakdown provides strategic insights for efficiently securing every available reward before the event concludes.
The Echoes of the Dead challenge series remains active through October 23, providing exactly seven days to accomplish all objectives and claim the complete eight-item reward collection. Premium BlackCell subscribers gain access to an additional ninth exclusive item unavailable to standard players.
Each unlockable item requires completing a single designated challenge, with three mode-specific options available per reward covering multiplayer combat, Zombies survival, and Warzone battle royale scenarios. Crucially, players only need to complete one challenge variant per desired item, enabling strategic selection based on personal gameplay preferences and perceived difficulty levels. This flexible approach accommodates diverse playstyles while maintaining accessibility across skill tiers.

The X52 Resonator represents Season 6’s premier special weapon addition, featuring an extraterrestrial design aesthetic directly inspired by Zombies mode lore and technology. Official weapon specifications from Activision characterize the X52 Resonator as a fully-automatic energy projector boasting exceptional fire rate statistics, enhanced effective range parameters, and significant recoil patterns requiring mastery through practice.
Weapon customization expands significantly through three distinctive Shard crystal modifications, each enabling fundamentally different combat methodologies. The Orbed Eruption Shard configuration delivers adaptable multi-projectile discharges ideal for medium-range engagements. Alternatively, the Spiked Barrage Shard provides methodical seven-round burst sequences with devastating stopping power per salvo. For precision specialists, the Stone Escalation Shard enables charged energy blasts capable of eliminating targets with single well-placed shots.
Acquiring this advanced weapon system requires successful completion of any single challenge from the following categories:







Beyond the primary energy weapon, the Echoes of the Dead event features seven additional unlockable items spanning practical attachments, cosmetic enhancements, and progression accelerators. The GPMG-7 Muzzle Booster attachment enhances weapon performance characteristics, while the Cool Helm weapon charm adds personality to your arsenal. Utility rewards include Double XP tokens for accelerated progression, complemented by visual customization options like the Blast Burn calling card and Weaponry large decal.
The standard Toxic Metal camouflage provides distinctive visual effects across compatible weapons, with BlackCell subscribers receiving an exclusive variant featuring enhanced animated elements and unique color schemes. This premium version demonstrates visible status while maintaining identical statistical properties to the base camouflage.
Strategic mode selection dramatically impacts challenge completion efficiency. Multiplayer eliminations typically accumulate fastest in objective-based modes like Domination or Hardpoint where player density remains consistently high. Zombies mode challenges benefit from focused farming in high-spawn areas during Haunted Havoc events, while Warzone eliminations prove most manageable in resurgence-style Zombies Royale matches with frequent reanimation mechanics.
Common strategic errors include attempting all challenge variants simultaneously rather than focusing on the most efficient option per reward. Additionally, players often underestimate the time investment required for Zombies mode challenges compared to multiplayer alternatives. For optimal time management, prioritize Warzone or multiplayer challenges during limited play sessions, reserving Zombies objectives for extended gaming periods.
Advanced optimization involves weapon loadout preparation specific to each challenge type. For elimination-based objectives, utilize meta weapons with high mobility and competitive time-to-kill statistics. In Zombies scenarios, equip area-of-effect weaponry and durability enhancements to maximize elimination rates during intense undead confrontations.
