Whether you’re grinding Multiplayer, exploring DMZ, or dropping into Battle Royale, there’s plenty to prepare for. Check the official MW4 Season 1 announcement for confirmed details. You can also brush up on your loadouts with our Modern Warfare 4 Create-a-Class Guide.
MW4 Season 1 Release Date and Launch Timeline
MW4 Season 1 goes live on November 6, 2026, at midnight ET (9 PM PT on November 5). The update rolls out across all platforms, with Warzone receiving its major MW4 integration at the same time.
Activision has confirmed November 6 as the launch date for the main seasonal update and for Warzone’s new content. Players can expect changes across Multiplayer, DMZ, and the free-to-play Battle Royale experience.
Here’s the confirmed launch schedule and content breakdown:
| Update Title | Release Schedule | Core Content & Feature Additions |
| MW4 Season 1 | November 6, 2026 | Multiplayer maps, game modes, weapon roster additions, and expanded DMZ content. |
| Warzone Season 1 | November 6, 2026 | Maps (Hajin, Zodiac), full MW4 integration, and updated core gameplay mechanics. |
| Season 1 Reloaded | Mid-Season 2026 | Mid-season refresh featuring bonus Multiplayer maps, extra game modes, and seasonal event content. |
The launch brings three new Multiplayer maps: Backstab, Canyon, and a reimagined Shoot House. DMZ players can enter the X01 facility, while Warzone introduces Hajin for Battle Royale and Zodiac for Resurgence.
Not everything arrives on day one, though. Ministry and Overflow are among the confirmed midseason Multiplayer additions, so players should expect more content as Season 1 progresses.
MW4 weapons, Operators, Battle Pass progression, and Player Level progression will now become part of the free-to-play experience. Players can also access new gameplay features and equipment, providing Warzone with a substantial update beyond its new maps.
MW4 Season 1 Multiplayer Maps and Game Modes
Season 1 adds Backstab, Canyon, and Shoot House to the Multiplayer map rotation, with Ministry and Overflow slated for the midseason update. Players also receive new and returning modes, including Gauntlet 1v1, Grind, and Drop Zone.
Brand New Multiplayer Maps at Launch
Three maps headline the Season 1 Multiplayer update:
- Backstab: A new map joining the launch rotation, offering players another close-quarters combat environment to learn.
- Canyon: Another launch addition that expands the Multiplayer map pool.
- Shoot House: The familiar fan-favorite returns, offering players a compact arena for fast-paced engagements and weapon challenges.
Shoot House deserves special attention from players who prefer aggressive gunfights and quick engagements. Its return also offers longtime Call of Duty fans a familiar location to revisit.
Returning Maps and Midseason Additions
The launch isn’t the end of the map rollout. Activision has also announced more maps for the midseason update.
- Ministry: Returns as a seasonal Multiplayer addition.
- Overflow: Joins the map rotation during the midseason content update.
Keep an eye on the Reloaded announcement for their confirmed availability dates. Don’t assume every announced map will be available on November 6.
New and Returning Multiplayer Modes
Season 1 also introduces several modes for players who want more than standard Multiplayer matches.
- Gauntlet 1v1: A competitive mode centered on individual matchups.
- Grind: Returns with its familiar objective-based scoring system.
- Drop Zone: Brings objective control and care package competition to the rotation.
The Gauntlet playlist also ties into the Wager Match Event, giving players another reason to test their gun skills and compete for seasonal rewards.
If you’re planning to grind weapon challenges or experiment with the new additions, check out our Modern Warfare 4 Create-a-Class Guide before jumping into the updated playlists.
MW4 Season 1 Weapons and Attachments
Season 1 introduces four headline weapons, including the Cronen Osprey Assault Rifle, CSG-35 SMG, JAK 12 Shotgun, and ZLR Talonhawk Melee Weapon. The first two are available through Battle Pass progression, while the latter are tied to seasonal unlock opportunities.
New Weapons Available Through the Battle Pass
Two weapons headline the Season 1 Battle Pass:
- Cronen Osprey Assault Rifle: A new primary weapon available through Battle Pass progression.
- CSG-35 SMG: Another Battle Pass weapon, giving players a fresh option for close-range engagements.
Both weapons deserve a place on your unlock priority list. Getting them early gives you more time to test their strengths, experiment with attachments, and find suitable loadouts before the season progresses.
Weapons Arriving Later in Season 1
Two additional weapons are scheduled for seasonal unlock opportunities:
- JAK 12 Shotgun: A returning shotgun joining the available weapon lineup.
- ZLR Talonhawk Melee Weapon: A new melee option arriving through seasonal content.
Check the relevant event challenges when these weapons become available. Official announcements will confirm exact unlock requirements and release dates, not assumptions.
New Weapon Attachments
Season 1 also introduces several attachments for players who enjoy experimenting with weapon builds. Announced additions include:
- Hyeon Auto Apex Attachment
- Kastov 545 Apex Attachment
- M16 Burst Attachment
These additions give players more options when customizing compatible weapons. Check the Gunsmith once the update arrives to review compatibility and choose attachments that suit your preferred playstyle.

MW4 DMZ Season 1: Everything Coming to the X01 Facility
The X01 facility is MW4 DMZ’s major new location, giving Operators a dangerous underground complex to explore near Hajin. The former weapons facility features underground laboratories, cargo bays, vehicle depots, and production lines, with a sealed Deep Vault adding another mystery for players to investigate.
What Is the X01 Facility?
The X01 sits near Hajin and serves as a major location in the Season 1 DMZ experience. Key locations include:
- Underground laboratories.
- Cargo bays.
- Vehicle depots.
- Production lines.
- The sealed Deep Vault.
Its history as a former weapons facility explains the industrial layout, with several areas offering different challenges for Operators.
New DMZ Orders, Enemies, and Equipment
Season 1 expands DMZ with specialized system protocols, including Threat Briefing contracts alongside Resupply Runs and new underground equipment tailored to the X01 experience. Expect to coordinate with your squad, manage available equipment, and watch for hostile forces as you work through the new content.
The new Orders also give returning DMZ players fresh objectives to pursue instead of repeating the same extraction runs.
Warzone Season 1 Roadmap: New Maps, Weapons, and Integration
Warzone Season 1 introduces Hajin and Zodiac, along with MW4 weapon integration and additional gameplay changes. Hajin offers the new Battle Royale setting, while Zodiac brings a dedicated Resurgence environment centered on a drone manufacturing complex.
Hajin: New Battle Royale Map
Hajin takes players to the Korean Peninsula for a new Battle Royale experience. Its blend of urban and rural environments offers squads a range of combat situations to prepare for.
It also ties into the broader MW4 storyline and the introduction of the X01 facility. Players interested in DMZ should pay attention to Hajin, as the two experiences share a key location. Focus on:
- Identifying major points of interest.
- Understanding routes between urban and rural areas.
- Finding suitable positions for rotations.
- Learning where your squad can safely engage or disengage.
Zodiac: New Resurgence Map
Zodiac introduces another setting at the DRC Advanced Systems drone manufacturing headquarters. Its industrial environment features production facilities, underground routes, moving trains, and environmental hazards.
The map offers Resurgence players a different kind of battlefield, with enclosed spaces and industrial structures that create opportunities for close-range encounters. Pay attention to the following features:
- Manufacturing facilities: Industrial spaces that shape how players approach engagements.
- Underground routes: Alternative paths through the complex.
- Moving trains: Environmental elements that affect movement and positioning.
- Hazards: Additional threats to consider when navigating the map.
Players who prefer aggressive Resurgence matches should spend time learning the facility’s routes before attempting risky rotations.
Verdansk and Rebirth Island Return
Hajin and Zodiac aren’t the only maps worth watching. The Season 1 roadmap also features Verdansk and Rebirth Island as part of Warzone’s seasonal content. Their inclusion pairs familiar locations with new environments.
Check official playlist announcements for availability. The current roadmap doesn’t guarantee every map will always be playable in every playlist.
Weapon Integration and Warzone Gameplay Changes
The biggest Warzone change goes beyond the new maps. Season 1 integrates MW4 weapons into the experience, giving players access to the new game’s weapon lineup and progression.
Activision also integrates prior content through the expanded Carry Forward initiative, allowing weapons and cosmetics from titles like MWII, MWIII, and recent entries to coexist within unified loadout menus alongside the new MW4 inventory.
Other seasonal additions include:
- New equipment.
- Additional perks.
- Movement and gameplay adjustments.
- New modes and playlist options.
- MW4 Battle Pass and Player Level progression.
This gives Warzone players more reasons to experiment with their loadouts instead of sticking to the same established weapon combinations.
Season 1 Battle Pass and Rewards
The MW4 Season 1 Battle Pass features 100 reward tiers. That includes weapon blueprints, Operator Skins, Calling Cards, Finishing Moves, Double XP Tokens, and DMZ Survival Kits. Players can progress through free and premium reward tracks, while BlackCell offers additional premium content.
Battle Pass Tiers and Unlockable Rewards
The 100-tier progression system gives players plenty to work toward throughout Season 1. Rewards include:
- Weapon Blueprints.
- Operator Skins.
- Calling Cards.
- Finishing Moves.
- Double XP Tokens.
- DMZ Survival Kits.
The Cronen Osprey Assault Rifle and CSG-35 SMG are also available via Battle Pass progression. Prioritize these unlocks to expand your loadout options early.
Battle Pass Catch-Up System
Season 1 introduces a catch-up mechanic for premium Battle Pass rewards. The system automatically advances premium reward access to match the current season day, up to Day 50. This gives players who purchase the premium pass later a chance to catch up on the available reward progression.
BlackCell Rewards and Premium Content
The BlackCell content offers another reward option for players seeking additional premium content. It includes exclusive cosmetics and other rewards beyond the standard Battle Pass selection.
Season 1 Patch Notes
The MW4 Season 1 update brings changes to Multiplayer, DMZ, and Warzone, but players should distinguish confirmed seasonal content from the official patch notes. The official Season 1 announcements confirm several major new additions:
- Three Multiplayer maps at launch.
- Weapons and attachments.
- The X01 DMZ facility and Orders.
- Hajin and Zodiac for Warzone.
- MW4 weapon integration.
- Equipment, perks, and seasonal progression features.
Weapon Balancing and Gameplay Adjustments
Weapon balancing deserves particular attention as Season 1 goes live, building on the initial weapon tuning passes and pre-season hotfixes that already adjusted platform performance across SMGs, LMGs, and movement mechanics.
Never assume a weapon has been buffed or nerfed just because players start discussing it online. Wait for the official notes before changing your loadouts.
Known Issues and Upcoming Fixes
New seasonal updates can introduce technical issues alongside their content additions. Players should monitor Activision’s announcements for confirmed bugs, server issues, and scheduled fixes. Pay particular attention to:
- Multiplayer matchmaking problems.
- Warzone performance issues.
- DMZ extraction or progression bugs.
- Weapon and attachment inconsistencies.
- Battle Pass reward tracking issues.
What Should You Prioritize in MW4 Season 1?
Your priorities should depend on which mode you play most. Multiplayer grinders should focus on weapons and event rewards, DMZ players should explore X01, and Warzone squads should learn Hajin and Zodiac before their competition gets comfortable.
Here’s a practical checklist:
- Multiplayer players: Unlock the Cronen Osprey and CSG-35, learn the new maps, and participate in Gauntlet 1v1.
- DMZ players: Explore X01, complete new Orders, and investigate the facility’s different areas.
- Warzone players: Learn Hajin and Zodiac, test MW4 weapons, and adjust your loadouts to the updated weapon pool.
- Completionists: Track Battle Pass progression, weapon camos, limited-time events, and mastery rewards.
One tip: Don’t leave event challenges for the final days. Some rewards take longer than others, and waiting until an event nears its end can turn a straightforward unlock into an unnecessary grind.
Final Thoughts
MW4 Season 1 brings a wide range of content to Multiplayer, DMZ, and Warzone. Players can explore new weapons and maps, take part in seasonal events, and pursue progression rewards throughout the season.
