The latest season of content adds snow-covered multiplayer maps Nuketown Russia and Raid Holiday, plus a winter update for battle royale.
Ski Town has been enhanced with new buildings and a ski course, while a new snowboard vehicle can now be used to get around the map.
The latest Battle Pass includes a winter-themed version of Ghost, CIA operatives Adler – Mountain Drab and Helen Park – Safehouse from Call of Duty: Black Ops Cold War, plus a new automatic assault rifle called the Peacekeeper MK2.
Another fresh gun, the QXR SMG, will arrive later in the season, as will new multiplayer mode Grind. A mixture of Kill Confirmed and Hardpoint, Grind challenges players to collect dog tags from fallen enemies before dropping them off at a deposit point.
More information on the new and upcoming content can be found in the Season 13 roadmap image below, as well in a recent Activision community update on Reddit.
