When does Modern Warfare 4 Season 1 start?
According to the roadmap Activision published on the PlayStation Blog, Season 1 opens on November 6, 2026. The update itself is free; the Battle Pass is a separate purchase. We covered the game's October 23 launch and its 20 launch maps in our Modern Warfare 4 launch story.
What new maps and modes are coming?
Three maps arrive on day one. Backstab is a new war-torn battleground fought in bad weather, littered with abandoned tanks and empty houses. Canyon plays out between towering rock walls and offers distinct routes, from the riverside Convoy Ambush area to the winding Cliff Path. Shoot House, an old favorite, returns reimagined against the rugged terrain of North Korea during a snowfall.
Two familiar modes are back. In Grind, you take down opponents, collect their dog tags and carry them to the Bank to score. In Drop Zone, teams fight to hold a single rotating objective while Killstreak packages are airdropped over the zone at regular intervals.
The content expands at Mid-Season with two more maps: Ministry, set in and around an embassy during a diplomatic summit, and Overflow, built around a factory and its surrounding farmland. The new Counter Attack mode has you trying to bomb the enemy's Comm Station while defending your own.
What does the X01 facility add to DMZ?
X01 is a previously undiscovered weapons facility that enemy forces have seized. Activision describes it as a maze of tunnels with shifting hazards that calls for squad coordination and specialized equipment. As you push deeper, the facility starts closing off extraction points, so you have to complete specific steps to escape. X01 also brings new pages of DMZ Orders, Threat Briefing missions against the biggest Boss threats, and Resupply Runs.
What changes in Warzone and the Battle Pass?
Call of Duty: Warzone gets two maps with Season 1: Hajin and Zodiac. Hajin shares its name with the region where Modern Warfare 4's DMZ and Ground War maps are set. Activision says a full Warzone roadmap is coming soon; the list of modes and features hasn't been announced yet.

The Battle Pass unlocks two new weapons: the Cronen Osprey assault rifle, which balances speed with moderate power, and the CSG-35 SMG, said to have the highest fire rate in its class. The pass follows a linear 100-tier track with more than 100 rewards. The new catch-up system automatically advances players who buy the premium pass and fall behind to the reward for the current day of the season; it applies up to day 50 of the season and guarantees buyers more than 50 rewards.
