Season 1 of Call of Duty: Modern Warfare 4 arrives November 6, bringing a broad update from developer Infinity Ward that includes new multiplayer maps and modes, expanded DMZ content and the official release of free-to-play Call of Duty: Warzone on the Nintendo Switch 2 platform.
The update is positioned as a major seasonal rollout, with additional mid-season content planned.
Multiplayer maps and modes
Season 1 introduces three 6v6 maps — Backstab, Canyon and Shoot House — plus a new Kill Block variant called Kill Block: Crash.
Backstab drops players into a snow-covered town with long-range sightlines and interior close-quarters combat.
Canyon offers heat-scorched terrain framed by towering rock walls that funnel engagements.
Shoot House returns in a North Korea–set environment during a light snowfall.
Infinity Ward has confirmed that in Kill Block: Crash all three developer-selected slabs remain fixed for the duration of the match, meaning the map configuration does not change between rounds.
New and returning multiplayer modes for Season 1 include Possession (a Halloween-themed mode in which eliminating an enemy causes the player to occupy that enemy’s position and take their loadout), Infected (survive or spread the infection), Grind (collect enemy dog tags and deposit them at the Bank), Drop Zone (secure a rotating objective and contest periodic airdrops) and Gauntlet 1v1 (a Wager Match Event 1v1 Gunfight where players wager trophies to claim victory).
DMZ: X01 and new objectives
A previously hidden weapons facility codenamed X01 opens as a new DMZ area.
Recon along the northern border of North Korea identifies an infiltration point through Hajin, allowing Operators to deploy into X01.
Season 1 adds DMZ Orders, new items and equipment, new enemy types and a Threat Briefing challenge that tasks players with eliminating a North Korean battle tank and an enemy called The Captain within X01.
Warzone on Nintendo Switch 2
Season 1 also marks the launch of Call of Duty: Warzone on Nintendo Switch 2.
The free-to-play battle experience debuts with the Hajin Battle Royale map and Zodiac Resurgence map, plus platform-specific features including the Hajin Gulag arenas, a Zipline Launcher for rapid traversal, and a Grabber Drone capable of retrieving loot and objects.
Warzone on Switch 2 includes the Grinding for Royalty system that generates personalized challenges tied to player stats, Weapon Augments that enhance weapons for the remainder of a match, and Ground Ops activities that reward high-value loot.
New and returning playlists such as Rally Point (tutorial-style matches) and Resurgence modes will be available at launch, with additional maps and modes set to arrive mid-season.
