The first full season of Modern Warfare 3 arrives on December 6. The latest Call of Duty blog post reveals exactly what players can expect for Season 1 of multiplayer and Zombies. The big update includes the first set of brand-new multiplayer maps, and Zombies gets a new story act and another Warlord fortress to defeat.

As to be expected with a new season of Call of Duty, the first season of Modern Warfare 3 and Warzone will include a new battle pass to level up and unlock more weapons and cosmetics. The season's new operators are Nolan and Dokkaebi. Season 1 brings five free new weapons and nine aftermarket parts to unlock.

Additionally, the $30 premium BlackCell pass returns, which includes the new Abolisher operator, extra tier skips, alternate BlackCell-exclusive skins earned throughout the pass, and more.

Season 1 of multiplayer includes three brand-new core 6v6 maps and one 2v2 map, which arrive alongside holiday reskins of other maps during the season. Call of Duty's Gunfight mode returns, which is the fast-paced 2v2 faceoff on small maps. In addition to the brand-new Training Facility map, there will be four classic Gunfight maps arriving.

The season includes new game modes. All or Nothing, which was introduced in the original Modern Warfare 3, is a free-for-all mode with a very limited loadout. A new Vortex mode themed around the Ray Gun from Zombies will arrive later in the season.

Two new killstreaks were announced. The Swarm is earned at either 15 kills or 1,875 points, and it deploys a large number of mosquito drones to a selected area. The EMP is earned at 13 kills or 1,625 points, and it provides an electromagnetic pulse to disrupt enemy killstreaks and equipment.

On the Zombies side, there's a new story act to complete, continuing the narrative of the first three acts. A massive gateway will appear on the map for players to investigate and engage in new end-game content.

Season 1 includes the addition of Dark Aether rifts. These are described as labyrinth-like experiences challenging squads to complete a series of objectives in the given time. Completing these rifts earns new rewards. The update also adds the V-R11 Wonder Weapon, new schematics to unlock, and a new Warlord fortress to infiltrate.

More shop bundles were announced for The Boys, Dune, and Santa. Players can also expect new daily, prestige, and seasonal challenges.

Warzone's Season 1 update arrives on December 6, which includes Modern Warfare 3 integration with the new Urzikstan map. Warzone's holiday event includes an LTM with a Zombie Santa and deer-hunting.
