Modern Warfare 4 Season 1 starts November 6: new maps, DMZ's X01 facility and Warzone's Hajin and Zodiac

Season 1 of Call of Duty: Modern Warfare 4 goes live on November 6, according to the official Season 1 announcement that Call of Duty posted on Steam on October 28. The update covers Multiplayer, the DMZ extraction mode and Call of Duty: Warzone, along with a new Battle Pass.

Multiplayer maps and modes

Season 1 is split into a launch wave and a mid-season drop.

When	Maps	Modes
Launch (November 6)	Backstab (new; a war-damaged area in bad weather with abandoned tanks), Canyon (new; high rock walls with a River route near the Convoy Ambush and a winding Cliff Path), Shoot House (reworked, now set in snowy North Korean terrain)	Grind (collect enemy dog tags and bank them for points), Drop Zone (hold one objective that moves around while Killstreak packages are dropped onto it)
Mid-season	Ministry (new; fighting in and around an embassy hosting a diplomatic summit), Overflow (new; a factory and the farmland around it)	Counter Attack (plant bombs at the enemy Comm Station and defend your own)

DMZ: the X01 weapons facility

DMZ gets X01, a previously unknown weapons site that enemy forces have taken over. Activision describes a network of tunnels with hazards that change, and extraction points that shut as a run goes on, so squads have to finish set steps to get out. The season also brings several pages of new DMZ Orders tied to X01, Threat Briefings on taking down DMZ’s biggest boss threats, and Resupply Runs.

Warzone

Warzone’s Season 1 update adds two maps, Hajin and Zodiac, together with extra modes and gameplay features. Call of Duty says a separate post with the full Warzone roadmap for the season is due on November 2.

New weapons and the Battle Pass

• Cronen Osprey assault rifle: built for speed with moderate damage.
• CSG-35 SMG: aimed at close range, with the top fire rate among SMGs according to Activision.

Both guns come through the Season 1 Battle Pass. The pass is a straight 100-tier track with more than 100 unlockable items, including Operator Skins, Weapon Blueprints and Finishing Moves. It also adds a catch-up system: premium pass owners who fall behind are automatically advanced to the reward for that day of the season, capped at day 50, which guarantees buyers at least 50 rewards.
