MW4 Season 1 Guide: Roadmap, Maps, Battle Pass, End Date

Modern Warfare 4 Season 1 started at midnight ET on November 6, 2026 (9 PM PT on November 5), two weeks after the game's October 23 launch. It brought three new Multiplayer maps, the X01 black site in DMZ, full integration with Warzone on the new Hajin and Zodiac maps, four new weapons, and a 100-tier Battle Pass that catches late buyers up. Activision has not published an end date for Season 1, and the mid-season Season 1 Reloaded update is also undated so far. This guide covers the roadmap, every map and mode, DMZ and Warzone content, the weapons, the Battle Pass and the events.

Checked against Activision's Season 1 announcement, Battle Pass post and Warzone Season 1 post, plus the MW4 Season 1 patch notes (updated November 11, 2026) on November 12, 2026.

Everything below is confirmed by Activision unless marked otherwise. Items listed for mid-season are announced plans, and Activision has kept some maps and DMZ details classified until closer to release.

When does MW4 Season 1 end?

Activision has not announced the end date. Neither the Season 1 announcement nor the Battle Pass post gives one, and the Season 1 Reloaded mid-season update has no date either.

The only timing clue is the Battle Pass: its catch-up system works up to day 50 of the season, which suggests Season 1 runs at least that long from November 6. Bonus Battle Pass rewards and the mid-season maps are also still to come, so the season is far from over. Watch the Season 1 Reloaded blog and the in-game Battle Pass screen for the official end date.

What new maps are in MW4 Season 1?

Three 6v6 maps at launch, a featured Kill Block layout, and at least two more maps at mid-season.

Map	Timing	Details
Backstab	Launch	New, medium, snow-covered war-torn town with long street sightlines and open buildings
Canyon	Launch	New, medium, sun-scorched canyon with a river, cliff path, cave and central mesa
Shoot House	Launch	Reimagined in snowy North Korea, same three-lane layout
Kill Block: Crash	Launch	Featured Kill Block combo with all three slabs locked; also added to core playlists including Search and Destroy
Shipment	Pre-season, October 27	Remastered small map on a Russian harbor
Ministry	Mid-season	Fight in and around an embassy at a Global Peace Summit
Overflow	Mid-season	Factory and farmland, with rocket launchers firing in the distance

Dot Esports reports that Backstab's layout is inspired by Burgundy from Call of Duty 2. Activision says more mid-season maps will be revealed in the Season 1 Reloaded post. The Shransit playlist, which rotates Shipment, Shoot House and Transit 213, went live on November 6, with Hardcore available through Quickplay.

What modes are in MW4 Season 1?

Grind and Drop Zone at launch, Gauntlet 1v1 through the Wager Match Event, and two more modes at mid-season.

What is new in DMZ for Season 1?

X01, a GRANIT Arms black site under Hajin's border that you reach by deploying through Hajin. It is a maze of cargo bays, labs, a production line and a sealed Deep Vault, with exfils the facility closes over time.

• Orders: Ghost is the Watcher for X01, with multiple pages of new DMZ Orders.
• Bosses: new Lieutenants Tae-Hyun ("Knuckle") and Chol-Min ("The Wrench"), and Commanders The Captain (a Juggernaut with an elite guard) and a patrolling autonomous Wheelson.
• Events: Threat Briefing (take parts from the Battle Tank in Hajin or helmet pieces from The Captain in X01, and exfil with them) and Resupply Run (trade items found at POIs for Self Revives and 3-Plate Carriers).
• FOB: a Battle Pass and Store station, and extra Vendor stock for BlackCell owners.

Infinity Ward has adjusted X01 since launch, disabling UAVs, Advanced UAVs and the Bombing Run there. The DMZ beginner guide explains the mode from scratch.
