The Season 1 Reloaded update has arrived in Call of Duty: Black Ops 6 and Warzone, introducing significant new content including the Citadelle des Morts Zombies map, Warzone Ranked Play competitive mode, and additional multiplayer battlegrounds. This midseason refresh also brings the festive Merry Mayhem limited-time event, featuring exclusive seasonal content such as the new Maelstrom shotgun, Shrapnel Radar multiplayer perk, and specialized weapon attachments alongside fresh Zombies equipment. Our comprehensive guide details every strategy to secure all available rewards during this holiday celebration.
Merry Mayhem remains active across Black Ops 6 and Warzone platforms through December 19. Each cosmetic and functional item is gated behind cumulative XP thresholds, meaning consistent gameplay across multiplayer, battle royale, and undead modes will progressively unlock your rewards.
Maximizing XP acquisition for Merry Mayhem requires strategic gameplay focusing on objective completion, diverse challenge fulfillment, elimination stacking, and match victories. Engagement in objective-heavy modes within compact map rotations like Nuketown 24/7 typically delivers optimal experience point yields for both player progression and event completion.
Players must conquer 10 distinct XP milestones before accessing the ultimate Mastery event reward tier, which grants the season’s powerful new Maelstrom shotgun.
Below you’ll find the complete breakdown of all event challenges and their corresponding unlockable items.

The event employs a straightforward cumulative XP system where your total earned experience across all game modes contributes toward milestone unlocks. Unlike traditional challenge-based systems, this approach rewards consistent playtime rather than specific skill demonstrations, making it accessible to players of all ability levels.
Common Mistake Alert: Many players waste time in low-XP modes like Team Deathmatch when objective-based alternatives offer significantly faster progression. Always prioritize Domination, Hardpoint, and Control matches for maximum efficiency.
Advanced players should combine daily challenges with objective play for accelerated gains. Completing weapon camo challenges alongside event progression can yield bonus XP while working toward multiple goals simultaneously.

Your first milestone at 9,000 XP grants the Holiday Fear emblem, featuring a macabre undead reindeer perfect for seasonal customization. This early reward provides immediate visual flair while you continue toward more substantial unlocks.
At 21,200 XP, you’ll unlock the Necroclaus loading screen, immersing you in festive undead atmosphere before each match begins.

Reaching 39,800 XP unlocks the Nasty Nick animated calling card, depicting a zombified Santa Claus hurling a frozen projectile. The dynamic animation adds personality to your player profile while showcasing your event dedication.


The mid-tier rewards include practical gameplay enhancements like Light Mend, a Zombies ammunition modification that simultaneously grants a Double Weapon XP token for accelerated firearm progression.

Death Claus emerges as a large decal option at higher XP thresholds, allowing for substantial cosmetic customization of your weaponry and equipment.

Tesla Storm provides both a Zombies field upgrade and standard Double XP token, offering both immediate tactical advantages and long-term progression benefits.

The Bitter Blizzard weapon charm adds seasonal aesthetics to your firearms, dangling from your weapon as a constant reminder of the festive chaos.

Pro Tip: The Shrapnel Radar multiplayer perk significantly enhances situational awareness by detecting explosive threats, making it invaluable in grenade-heavy engagements. This represents one of the most significant gameplay enhancements from the event.

Additional rewards include Double Battle Pass XP tokens for accelerated seasonal progression and the 3-Round Burst weapon attachment, which also includes a Blackcell Drill blueprint variant for additional customization options.


The ultimate Mastery reward is the Maelstrom shotgun, a powerful new addition to your arsenal available only after completing all preceding milestones.
