Call of Duty: Mobile's Season 11 — Siren Song arrived with the subtlety of a snowplow in a china shop: a once-in-a-century winter storm, a runaway assassin named Siren, and enough holiday décor to make a shopping mall jealous. Siren had just escaped a secret government assassin training program bankrolled by Atlas, and naturally her first order of business was to headline a Battle Pass. In 2026, the original seasonal calendar has long since rotated, so players should treat the Siren Song schedule as a time capsule rather than a live to-do list. Still, as a case study in festive mayhem, it remains a chilly little classic. Who wouldn’t want to celebrate the holidays by planting a tree and then shooting everyone who tries to water it?

The Siren Song Battle Pass: Free Toys and Premium Frosting
The Siren Song Pass split its gifts into free and premium piles. Free-tier players could grab the new Misdirection Battle Royale class at Tier 14, then pick up the Groza Assault Rifle at Tier 21 — a full-auto weapon with excellent handling speeds, a fast fire rate, and solid damage. Other free highlights included a variety of Camos, Weapon Blueprints, and the Koshka — Season’s Floral at Tier 50. Is a free assault rifle with good handling the holiday gift that keeps on giving? For anyone who enjoys not reloading at the worst possible moment, yes.
Premium Pass buyers got the winter wardrobe: Alex — Sweater Weather, Soap — Buzzard King, Lerch — Chemical Santa, and Roland — Vinterblood. Weapon Blueprints included the M4 — Ice Leopard, the RPD — Elemental Aggression, the PP19 Bizon — Chemical Burn, and the Groza — Final Gift. The Battle Pass Subscription added Ground Forces rewards such as the Shigenori — Bone Chiller Operator Skin, the Kilo 141 — Danger Skater Weapon Blueprint, and the Backpack — Danger Skater, plus a 10% boost to Player and Weapon XP, discount coupons, and limited discounts on 10x crate pulls. Starting with Season 11, players who bought the Battle Pass for three consecutive seasons also earned a unique Calling Card. Loyalty, it turns out, can be rewarded with something other than a stern nod.
Miami Blitz and the Surprise Skill Playlist
Miami Blitz received a holiday-themed makeover: festive lights, decorations, and Christmas trees that promised good cheer while players engaged in fierce close-quarters combat. A holiday truck hauling goods and treats offered a mobile platform for bad decisions. Hop on the back, eliminate anyone who tries to spoil the celebration, and try not to think too hard about the insurance paperwork.
The Surprise Skill Playlist asked players to think fast on their feet. New skills activated every 30 seconds, with a countdown showing exactly when the next change would hit. Two versions existed: one where all players received the same uniform change, and one where each player received a different feature for truly chaotic fights. Possible skills included Cranked — a boost to combat abilities that required eliminations to keep the bomb timer from reaching zero — plus Double Jump, Long Slide, and the Bull Charge Operator Skill. Who needs a calm, predictable match when a countdown can turn everyone into a caffeinated kangaroo?
Battle Royale: Christmas Trees and Misdirection
Battle Royale joined the festivities by handing players a sapling at the start of every match. Plant it, fertilize it, decorate it, and receive rewards. Fertilizer and decorations could be collected throughout the match; adding fertilizer helped the tree grow, and a bigger tree allowed more decorations for extra holiday cheer. It was gardening with a side of gunfire, which is exactly the kind of lifestyle brand Battle Royale had been missing.
The new Misdirection class brought a sonic generator that confused enemies by emitting special sound waves. Those waves impaired auditory functions, completely hid the user’s sounds, and caused enemies in range to hear fake noise sources. The class also enjoyed a passive increase to movement speed. In other words, it was a class for players who believed the best way to win a fight was to make the enemy question their own ears. Is that sneaky? Absolutely. Is it also very funny? Also absolutely.
Events, Challenges, and the Ballistic Knife
The Christmas Event turned daily missions into energy, and energy into tree placement and decoration. Complete a tree, move to the next one, and collect milestone rewards along the way. Those rewards included the M13 — INTERLOCK ADV Weapon Blueprint, the Bathysphere — Deep Season Operator Skin, and more. Seasonal Challenges and Featured Events offered Battle Pass XP, the new Operator Skill — Misdirection Device, and Season 11 Mission Tokens. Those tokens could be spent in the Seasonal Store on Operator Skins, Weapon Blueprints, and the new Ballistic Knife — a swift melee weapon paired with bladed projectiles for distant slaying. A knife that can stab from range is either a marvel of engineering or a sign that someone in the design room said, “Yes, but what if it were ruder?”
The Elite Mission: Kurohana Crate demanded dedication. Players needed six Legendary Medals by reaching Legendary Rank in Multiplayer or Battle Royale, plus four Confidential Tokens from special missions released throughout the year. The prize was the free Legendary DR-H — KUROHANA-68 Weapon Blueprint. In 2026, that grind is best viewed as a museum exhibit labeled “Extreme Holiday Commitment.”
Deals, Draws, and Mythic Siren
The 12 Days of Deals brought discounts on gear such as the Christmas Series Armory, the Jingle Jingle Draw, and Siren’s Song Mythic Drop. Each day offered new discounted items, with the first day beginning December 21 at 4 PM PT. The Store also welcomed the Mythic Siren Operator Skin, complete with an Execution mode where Siren summoned a wave that enveloped enemies in a vortex of water, slammed them to the ground, and shattered them into ice shards. Her accompanying Weapon Blueprints were the BK57 — Spectral Song Assault Rifle and the Melee — Siren’s Razor, plus themed Skins for the Battle Royale plane and the Misdirection Operator Skill. The finishing move suspended enemies upside down in mid-air before slamming them back down. Subtle? No. Memorable? Very.
A new Mythic Weapon Draw offered a Mythic version of the Grau 5.56, designed with prototype technology and featuring a detailed science fiction–inspired inspection and a Death Effect animation. The draw also included the Foxtrot — Unseen Angel, Katana — Sharpest Claw, and the Legendary Trip Mine — Phantom’s Keep. The Christmas Series added six Draws, each with its own holiday-themed Legendary Weapon Blueprint. From December 7 through January 7, a Double COD Points event doubled the premium currency on qualifying purchases. Who could resist double points and a snowman with a rifle?
Battle Pass Vault and the 2026 Reality Check
The Battle Pass Vault was updated for Season 11 with content from Season 5 — Tropical Vision (2022). Players could earn Epic Operator Skins and Weapon Blueprints they missed, including Rampage, Park — Survivor, Rosa — Animal Instincts, and Rivas — Smuggler, plus the AK-47 — Mania, Oden — Megalodon, PKM — Bamboo Ballistics, and Kilo Bolt-Action — Stalk. For collectors, the Vault was less a storage room and more a haunted attic of missed opportunities.
In 2026, the key caveat is simple: live seasonal events are time-limited, and the original Siren Song calendar is not still ticking away. Players should check the current in-game Events tab and any active rotations rather than chasing expired dates. The season remains a useful snapshot of how Call of Duty: Mobile mixed holiday cheer, mythic spectacle, and chaotic playlists into one winter storm. It was loud, chilly, and occasionally ridiculous — which, for a holiday shooter, is basically a greeting card.
Season 11 — Siren Song launched on Call of Duty: Mobile on December 6 at 4 PM PT. In 2026, that date is a memory, but the image of a water-vortex execution and a Christmas tree ambush is forever. 🎄❄️🔫
