Modern Warfare 4 Season 1 Is Live With Shoot House, Hajin and a New Battle Pass

Call of Duty Modern Warfare 4 Season 1 is live now. It went live at midnight ET on November 6, 2026, which was 9 PM PT on November 5. This is the first seasonal update for Modern Warfare 4, which launched on October 23, 2026. The update brings three new 6v6 multiplayer maps, two new modes, a new DMZ Exclusion Zone, a fully integrated Warzone with a new Battle Royale map, a new Resurgence map, new gear, two free base weapons, a 100 tier Battle Pass, and a set of weapon balance changes. Ranked Play was not announced with Season 1.

Three New 6v6 Maps Lead the Multiplayer Update

The heart of Season 1 for many players is the multiplayer map list. Three new 6v6 maps arrive at launch, and each one points in a different direction. Backstab is a snow covered town, which should give players a cold and open setting with clear sight lines and plenty of cover to work around. Canyon is a desert map walled by rock, which sounds like a tighter space where fights can start fast and end just as fast. The third map is the one most players will talk about first, because it is a reimagined Shoot House set on North Korean terrain with the classic layout.

Shoot House has always been a map about pace. The classic layout keeps players close together, and the action rarely stops for long. A reimagined version that keeps that layout should feel familiar from the first match, even if the setting looks different. A familiar layout lets players focus on gunfights instead of learning every corner from scratch. Backstab and Canyon will take longer to learn, and the first days of a new season are the best time to learn, because everyone is learning at the same time.

Grind, Drop Zone and Gauntlet Give Players New Ways to Play

Season 1 also adds new modes to multiplayer. Grind and Drop Zone arrive with the update, and Gauntlet 1v1 comes through the Wager Match event. That gives players more than just new maps to try. It gives them new reasons to play, new goals inside a match, and new ways to test their skill against other players. Each mode will suit a different kind of player, and the best way to find out which one fits you is to play both a few times and see which one keeps you coming back.

Gauntlet 1v1 through the Wager Match event is a different kind of test. A one on one match leaves no room to hide. Every decision matters, from the weapon you pick to the route you take and the moment you choose to push or hold back. It is a good way to sharpen your aim and your timing, and it is also a good way to learn how strong your favourite loadout really is when you cannot rely on a team to cover you. If you want a focused challenge in Season 1, this is the mode to try first.

DMZ Gets a New Exclusion Zone Under Hajin

DMZ players get a new Exclusion Zone called X01. It is an underground GRANIT Arms facility beneath Hajin, and that setting alone sets it apart from the open maps that many players know well. An underground facility means tighter spaces, shorter sight lines, and a different kind of tension. You cannot always see what is coming, and you cannot always run far to get away from a fight. That kind of space rewards careful movement, listening, checking corners, and thinking about where to go next before you move.

DMZ has always been about risk and reward. You go in with a plan, you gather what you need, and you try to get out in one piece. A new Exclusion Zone adds a new place to test that plan, and it gives regular DMZ players a fresh reason to return. The first runs through X01 will be about learning the layout, finding the safe paths, and working out which fights are worth taking and which ones are better left alone. The link to Hajin matters too, because Hajin is also the name of the new Warzone Battle Royale map, which ties the two parts of the game together.

Warzone Is Now Fully Integrated With a New Map in South Korea

Warzone is fully integrated with Modern Warfare 4 in Season 1. The headline change is a new Battle Royale map called Hajin, set in South Korea. A new Battle Royale map is a big moment for Warzone players, because the map is the stage for every match. It shapes where players land, where they fight, and how the final circle plays out. A fresh map means fresh landing spots to learn, fresh routes to plan, and fresh places to hold when the zone starts to close.

There is also a new Resurgence map called Zodiac. Resurgence plays at a faster pace than Battle Royale, with quicker returns to the fight and more constant action. A new map for that mode gives players another place to learn the flow of fast respawns and close range fights. New gear arrives with the update as well. The Zipline Launcher and the Grabber Drone give players new tools to move and to gather items, and Elite Perks add another layer to how a loadout can be built. The right piece of gear can change a fight, but only if you know when to use it. Warzone no longer runs on PlayStation 4 or Xbox One, so players on those older consoles will need to move to a newer system to keep playing.

The Season 1 Battle Pass and Weapon Balance Changes

The Season 1 Battle Pass has 100 tiers. The premium version costs 1,100 COD Points, and the bundle costs 2,400 COD Points. BlackCell costs 29.99 dollars and includes the XERO Operator. That gives players three clear choices, and the right one depends on how much you play and how much you want from the pass. The catch up system is the part that many players will welcome most. If you buy the premium pass later in the season, the system moves you to the reward that matches the current day of the season, up to Day 50. That means a late start does not leave you far behind everyone else.

The Battle Pass also includes two new free base weapons, the Cronen Osprey and the CSG-35. Free base weapons matter because every player can earn them, not just players who pay for the premium pass. They also change the weapon pool for everyone, which means the meta can shift as players learn what each new weapon does well. Weapon balance is a key part of Season 1 too. The biggest change is a nerf to the Hyeon Burst assault rifle. The Hyperburst Apex attachment got a big damage nerf. Maximum damage is down from 30 to 23, and minimum damage is down from 25 to 20. There are also buffs for the Axion, the Kastov 762, the Han 86, the Patriot XMR, and others. If you have a favourite weapon that felt weak before Season 1, this is a good time to try it again. The patch notes published on November 5, 2026, give the full list.

One thing that did not arrive with Season 1 is Ranked Play. It was not announced with the update, so competitive players will need to wait for news on when it will return. That does not take away from the rest of the update, but it is worth knowing if ranked matches are the main reason you play. For now, the focus is on the new maps, the new modes, the new Warzone content, and the Battle Pass.

Final Thoughts

Modern Warfare 4 Season 1 is a wide update, and that is its main strength. It adds three multiplayer maps, two new modes, a 1v1 event, a new DMZ Exclusion Zone, a new Warzone map in South Korea, a new Resurgence map, new gear, two free weapons, and a 100 tier Battle Pass with a catch up system that helps late starters. The Hyeon Burst nerf and the buffs for other weapons should also shake up the loadouts that players have settled into since launch. The one gap is Ranked Play, which was not announced with Season 1. Start with Shoot House if you want something familiar, try Hajin if you want a fresh Warzone map, and give the new weapons a fair chance before you settle on a loadout.
