Call of Duty: Warzone Season 1 Takes the Battle to South Korea
The Korean conflict at the heart of Modern Warfare 4 is about to spread considerably further. Activision and Infinity Ward have detailed Call of Duty: Warzone Season 1, launching November 6 and completing the free-to-play battle royale’s integration with Call of Duty: Modern Warfare 4.
The update introduces two new maps, new equipment and mechanics, expanded modes and a fresh progression cycle, while bringing Warzone to the Korean Peninsula for the first time.
The full reveal follows our earlier look at Modern Warfare 4 Season 1, where Activision initially confirmed Hajin and Zodiac alongside the wider Multiplayer and DMZ roadmap. The newly released official Warzone Season 1 breakdown now fills in considerably more of what changes when the update arrives.
Hajin Brings Battle Royale to the Korean Peninsula
Call of Duty: Warzone Season 1’s headline addition is Hajin, a large-scale Battle Royale map narratively connected to the Modern Warfare 4 campaign and the same Korean conflict zone already explored through DMZ.
Hajin stretches across 13 major Points of Interest spanning North and South Korea, moving between dense city streets, farmland, rivers, forested hills and heavily fortified military locations. Variable weather can bring fog, wind and rain across different parts of the map, while eliminated players will encounter two variations of a new Hajin Gulag affected by those same conditions.
That overlap with DMZ should make parts of the landscape familiar to anyone who has already spent time extracting from Hajin. Our Call of Duty: Modern Warfare 4 review found the region particularly effective as the foundation for the substantially expanded extraction mode, but the Battle Royale version changes vehicle availability, loot distribution and environmental rules to accommodate its shrinking circle.
Resurgence gets its own new battleground with Zodiac, a more compact map centred on the DRC Advanced Systems drone manufacturing headquarters. Its 10 POIs combine factory floors, laboratories, rooftops and underground passages, with moving trains and other interactive machinery adding opportunities for squads to reposition or turn the environment against opponents.
Modern Warfare 4 Fully Integrates Into Warzone
The integration also gives Call of Duty: Warzone a significant progression reset. Player Level begins again with Season 1, while progress and optional Prestige now extend across Multiplayer, DMZ and Warzone. All 33 Modern Warfare 4 launch weapons enter the free-to-play game alongside Season 1 additions, complete with Weapon Prestige, Apex Attachments and dedicated Mastery Camos.
Older content is not disappearing. Weapons stretching back to Modern Warfare II, Modern Warfare III, Black Ops 6 and Black Ops 7 remain available through a Legacy tab, although they will not support the complete suite of Modern Warfare 4 Gunsmith and customisation systems.
Legacy Operators and cosmetics also carry forward, alongside the new option to replace older character skins with Modern Warfare 4 Operators on the player’s own screen.
Grabber Drones and Movable Cover Change the Battlefield
Call of Duty: Warzone Season 1 also makes the maps more interactive. The new Grabber Drone can remotely pick up objects, including explosive fuel barrels, while cover such as concrete cylinders and other environmental items can be pushed or repositioned. Squads can therefore construct temporary defensive positions, block roads, or set up traps rather than treating the environment as completely static.
Other changes include the Zipline Launcher, Elite Perks, Weapon Augments and Ground Ops, while Tactical Sprint becomes available to every Operator without requiring a Perk. Players can also drag wounded allies while reviving them, along with further weapon balancing, improved map visibility, and revised footstep audio.
Battle Royale and Resurgence remain the main attractions, joined at launch by Casual variants, Rally Point, Massive Resurgence and Loaded Resurgence. Rally Point offers a no-circle, infinite-Resurgence environment intended for learning Warzone’s systems, while Massive Resurgence pushes Hajin up to 120 players. Extreme Resurgence and Rockets and Snipers will follow later in the season.
Call of Duty: Warzone Arrives on Nintendo Switch 2 as Older Consoles Bow Out
Season 1 also marks Call of Duty: Warzone’s debut on Nintendo Switch 2, with Hajin, Zodiac and the wider playlist joining the platform alongside the new season.
At the same time, Activision is ending support for PlayStation 4 and Xbox One. Warzone will no longer be playable on either previous-generation system once Season 1 begins, although existing progression can carry across when players sign in to a supported platform with the same Activision account.
It makes November 6 considerably more than another seasonal content drop. Between two new maps, full Modern Warfare 4 integration, a fresh progression cycle, and another platform joining the fight, Season 1 effectively establishes the next version of Warzone with Korea now at its centre.
