Call of Duty: Modern Warfare 4 content reaches Warzone with Season 1 on Nov 6, 2026 (per Activision's roadmap as reported by Insider Gaming): MW4's weapons, level unlocks, camos and progression, the Hajin Battle Royale map and the Zodiac Resurgence map. Operators, skins and Blueprints from Modern Warfare 2 through Black Ops 7 carry forward, and a new toggle shows every other player as an MW4 Operator.
Modern Warfare 4's content comes to Call of Duty: Warzone with Season 1, which starts Nov 6, 2026, per Activision's roadmap as reported by Insider Gaming. Until then Warzone runs its current version. From Season 1, Warzone will "integrate Modern Warfare 4 content and seasonal progression as part of a connected experience between both titles", in the words of Activision's announcement (May 28, 2026): MW4's weapons, level unlocks, camos and challenges, two new maps (Hajin for Battle Royale and Zodiac for Resurgence), and a Carry Forward plan that keeps Operators, skins and Blueprints from older games. This page sets out what changes, when, and what stays.
Quick facts
| When | Season 1, Nov 6, 2026 (Activision's roadmap, as reported) |

When it happens
Activision's own posts say only that Season 1 comes "shortly after launch". The date, Nov 6, 2026, comes from the roadmap image Activision released on Oct 14, which Insider Gaming and Inven Global reported; it marks Season 01 for both Modern Warfare 4 and Warzone. No start hour has been given as of Oct 25, 2026. The rest of the season is on Season 1 and Roadmap.
Until then, Warzone is the version that was live before Modern Warfare 4. "The new version of Warzone will not be available until the launch of Season 1", Call of Duty's updates account posted on Oct 13, quoted in Infinity Ward's patch notes; installing Warzone during pre-load gave you the current live game.
One install
Modern Warfare 4 and Warzone share one Call of Duty install, which shares content to save space and lets you switch between them in the same session once Warzone updates for Season 1, per Activision's Aug 19 post. During pre-installation you choose content packs, including whether to install Warzone at all. On Steam both run inside the shared "Call of Duty" app, which is why Modern Warfare 4's own player count cannot be separated (see Steam Player Count).
The new maps: Hajin and Zodiac
Two new Warzone maps arrive in Season 1, says Activision's Aug 21 Multiplayer post: "The DMZ map Hajin is also coming to Battle Royale", and Zodiac, built by Beenox, is a Resurgence map with a train.
Hajin is the map of DMZ: an exclusion zone on the borders of Russia and the Korean peninsula, with a prison, an air base, Hajin City and a damaged nuclear reactor. GameSpot's review calls it "the largest map ever created for Call of Duty", larger than Verdansk and Black Ops 7's Avalon. Insider Gaming noted (Aug 21, 2026) that it is unclear whether the radiation effects of DMZ come with it, and Activision has not said as of Oct 25, 2026. One difference is known: vehicles in Warzone need no repair or refueling, unlike in DMZ (Oct 5 DMZ deep dive). The Aston Martin Dreadnought, an armored V12 SUV, can be found at key points of interest in both DMZ and Warzone (Jul 16, 2026).
Zodiac has already been played. It was in Weekend Two of the Open Beta from Aug 28, 2026 as 44-player Resurgence, and in the Switch 2 beta as well: the DRC Advanced Systems drone assembly headquarters, with an Admin building, a double Trackline with trains, an R&D facility, docks and tunnels. Activision has not said as of Oct 25, 2026 whether Verdansk and Warzone's other current maps stay in rotation after Season 1. The clip is Activision's Zodiac reveal for the beta's second weekend: a drop over the town, then fights among wind turbines and solar panels.
Weapons, levels and camos
Modern Warfare 4's launch weapons are listed by Activision as "Available Across: Multiplayer, DMZ, Call of Duty: Warzone", with the note "(Call of Duty: Warzone content integration arrives in Season 1 later this year.)" (Oct 19 Operators and weapons blog). The full list is on Weapons.
From Season 1, MW4's Level Unlocks apply in Warzone, and Warzone XP counts toward the Level 1 to 55 track, though never toward the DMZ Level (progression blog, Oct 19, 2026). The weapon camo grind is shared by Multiplayer, DMZ and Warzone, and Warzone gets its own Daily Challenges and three Mastery Camos, Parallax, Damascus Reforged and Empyros, whose challenges stay "[CLASSIFIED]" until Season 1. See Ranks and Unlocks and Camos.
The meta is meant to change too. Activision's Sep 24 post says the aim is for Warzone's meta to "feel distinctly rooted in Modern Warfare 4", with Raven Software balancing weapons every two weeks. Modern Warfare 4's full movement set, from sliding to mantling and climbing, will be in Warzone as in every other mode (Aug 21, 2026); see Movement and Gunplay.
Carry Forward: what you keep
Operators, Operator skins and weapon Blueprints from Modern Warfare 2, Modern Warfare 3, Black Ops 6 and Black Ops 7 stay usable in Warzone from Season 1, per Activision's Sep 24 post. Legacy weapon camos do not; the post was corrected to say so.
Legacy weapons move to a Legacy tab in the loadout menu. They do not use the Gunsmith or old custom loadouts, but each legacy base weapon gets a fixed five-attachment version unlocked through the Armory, and legacy Blueprints keep their attachments. Dexerto's summary says legacy weapons "can only use default attachments", which differs from Activision's own wording; this page follows Activision's.
Pre-order rewards cross over too: the Hunter Killer Operator skin unlocked at once in Black Ops 7 and Warzone for pre-orders (editions blog, May 28, 2026), and the C.O.D.E. Valor Pack, sold in Multiplayer and DMZ since launch, reaches Warzone with Season 1 (launch post, Oct 23, 2026). See Editions and Pre-order Bonuses.
The Operator Skin toggle
Warzone gets a new setting in Season 1: the Operator Skin toggle. It is off by default; turned on, it shows every other player as a Modern Warfare 4 Operator on your screen, while your own Operator does not change (Sep 24, 2026). It exists only in Warzone. MW4's own Operators are on Operators.
PS4 and Xbox One
Modern Warfare 4 is not on PS4 or Xbox One, and Warzone on those consoles ends with Season 1. Activision's announcement set the steps: new downloads on PS4 and Xbox One ended on Jun 4, 2026, the in-game store there closed on Jun 25, 2026, and the game stops being playable on them when Season 1 launches. Platforms are on Platforms and Cross-play.

Season 1 and RoadmapModern Warfare 4 Season 1 starts on Friday, Nov 6, 2026, bringing the first Battle Pass and BlackCell and moving Warzone to Modern Warfare 4 with the Hajin and Zodiac maps. Before it, Shipment arrives on Oct 27 and the Halloween modes Possession and Infected follow that week.
- Steam Player CountSteam has no player count for Call of Duty: Modern Warfare 4 alone, because the game runs inside the shared "Call of Duty" app (1938090) with Warzone, Black Ops 6 and Black Ops 7. All Call of Duty on Steam had 217,019 players at 17:01 UTC on Oct 25, 2026, and peaked at 227,622 at MW4's launch, about double Black Ops 7's launch but below Black Ops 6's.

HajinHajin is the DMZ map of Call of Duty: Modern Warfare 4, an exclusion zone where Russia, North Korea and South Korea meet, with 13 major points of interest from the 14th Political Prison and Chang-san Air Base in the North Korean west to The Grid and the Haneul Nuclear Reactor in the South Korean east. It becomes a Warzone Battle Royale map in Season 1.
-
DMZDMZ is Call of Duty: Modern Warfare 4's PvPvE extraction mode: you deploy solo or in a squad of up to three into the Hajin Exclusion Zone, loot, complete missions, fight North Korean forces and rival players, and keep only what you carry out on an exfil. It is part of the paid game, not free like Warzone.

Open BetaThe Modern Warfare 4 beta ran over two weekends: Early Access for pre-orders from Aug 21 to 25, 2026, and an Open Beta for everyone, Nintendo Switch 2 included, from Aug 28 to Sep 1, 2026. It had six Core maps, Kill Block, Ground War, the campaign mission Entrenched and Warzone Resurgence on Zodiac, with cosmetic rewards to Level 30; its feedback raised the time to kill and every killstreak's cost by one kill.
