Season’s Eatings! Santa Gnaws is here to terrorize all who would disobey him. Prove your worth by completing up to eight challenges in the Santa’s Slayground in-game event to earn prizes more impressive than a lump of coal. Get rewards like consumable items and cosmetics such as the “Christmas Skulls” Calling Card, the “Elfsecution” Finishing Move, and the Weapon Blueprint/Operator Skin.
Play across new themed maps and modes as you complete the challenges in Multiplayer, Zombies, and Call of Duty: Warzone.
Themed Maps and Limited Modes in Multiplayer
CODMAS brings two holiday-themed map reskins with Shipmas and Hangover, plus Infectious Holiday and Snowfight as a twist on two fan-favorite party modes.
Shipmas

Pack your ugly sweater and deploy to the frozen sea in this cold-weather version of Shipment. Keep your head on a swivel to avoid joining the other corpses in cold storage.
Hangover

Toast to the New Year in this winter-themed Highrise decked with lights, garlands, and festive flair. The battle takes place at night for a new gameplay experience, so bring your best and celebrate in the victory screen.
New Limited-Time Modes
Infectious Holiday

Play Infected in a lobby full of Santa Claus Operators. Infected players will transform into the Zombie Santa Skin. Combine cheerfulness with combat prowess to retain those rosy cheeks against the undead menace.
Snowfight

In this Gunfight iteration, the first two rounds are decided by a snowball fight. These snowballs hit hard, so stay light on your feet. Capture the suspiciously yellow snowball in the center of the map for a one-hit elimination. After regular Loadouts return in the third round, players can still loot snowballs placed throughout the map.
