Modern Warfare 4 Season 1: Release Date, New Maps and Weapons

Call of Duty: Modern Warfare 4's first major content drop is locked in. Activision confirmed on October 28 that Season 1 goes live November 6 across PC, PlayStation 5, Xbox Series X|S and Nintendo Switch 2, bringing new multiplayer maps, a fresh DMZ facility, two weapons and a 100-tier Battle Pass to the game less than two weeks after its October 23 launch.

A shorter Halloween pre-season lands first. Infected and Possession modes arrive the Friday before Season 1, on October 30, giving players something to dig into ahead of the full seasonal update.

It's a fast turnaround for a game that's barely two weeks old. Modern Warfare 4 launched October 23 on PC, PlayStation 5, Xbox Series X|S and Nintendo Switch 2, with a campaign built around a North Korean invasion of the Korean peninsula and a separate thread following Captain Price on an off-book mission of his own. Season 1 is the first sign of how Infinity Ward plans to keep that launch lineup growing.

01New Multiplayer Maps and Modes

Season 1 opens with three new 6v6 maps: Backstab, Canyon, and a reimagined take on the series staple Shoot House, rebuilt for a snowfall setting in North Korea. Two modes launch alongside them. Grind tasks players with eliminating opponents, recovering their dropped dog tags, and depositing them at a map-specific Bank for points, while the returning Drop Zone has players fighting over a moving capture zone.

Activision is also holding content back for a mid-season update: two more maps, Ministry and Overflow, plus a new mode called Counter Attack, where teams plant and detonate bombs at the enemy's Comm Station.

02DMZ's New X01 Facility

DMZ, Modern Warfare 4's extraction mode, gets its own new location in X01, described as a previously undiscovered weapons facility now held by enemy forces. It's built around tunnels, hazards that shift over the course of a match, and extraction points that close as the raid goes on, raising the stakes for squads trying to get their loot out.

Alongside the new map, Season 1 adds new equipment, DMZ Orders, Threat Briefings that task squads with taking down named Boss threats, and Resupply Runs for players who need to restock mid-raid. None of it has been detailed further than that by Activision yet, so treat specific loadout or loot tables you see elsewhere as unconfirmed until the studio publishes its own breakdown closer to launch.

03Warzone Gets Two New Maps

Warzone's Season 1 update adds two maps of its own, Hajin and Zodiac, alongside additional modes and features that Activision says it will detail in a full roadmap "soon." The publisher has specifically pointed players to November 2 for a complete breakdown of Warzone's Season 1 content, two days before Season 1 itself goes live.

Season 1's Warzone content also includes BlackCell cosmetics fronted by returning Operator XERO, and a Call of Duty Endowment (C.O.D.E.) Valor Pack. The Endowment is Activision's long-running veteran employment charity, and bundling a themed pack into the season is a format it has used in past Call of Duty titles to tie a purchase to the cause.

04Two New Weapons

Season 1 ships with two weapons. The Cronen Osprey is an Assault Rifle Activision describes as balancing speed with moderate power, aimed at players who want a middle-ground option rather than a specialist's rifle. The CSG-35 is an SMG built around the highest fire rate in its class, designed for fast kills at close range rather than sustained fights.

05Battle Pass and the Catch-Up System

Modern Warfare 4's Battle Pass arrives with Season 1 as a linear, 100-tier track carrying Operator Skins, Weapon Blueprints, Finishing Moves and more than 100 unlockable items in total. Activision is pairing it with a catch-up system that guarantees over 50 rewards to players who buy the premium pass: if you fall behind, logging back in automatically bumps you up to the reward for the current day, up to day 50 of the track.

06When Season 1 Launches

Activision hasn't published an exact time of day for the November 6 rollout, and the studio's own materials stop at the date itself. Treat any specific launch hour you see elsewhere as an estimate rather than confirmed fact until Activision or the official Call of Duty channels post one.

Season 1 marks the first real test of how Modern Warfare 4 sustains itself past launch, and between the DMZ overhaul, the Warzone map additions, and a mid-season map pair already confirmed, Activision is front-loading a lot of content into the opening stretch. The November 2 Warzone roadmap post is the next date worth watching before Season 1 itself arrives on November 6.
