MW4 DMZ X01 Map: GRANIT Black Site Access & Season 1

What is X01 in MW4 DMZ?

X01 is the second map in Modern Warfare 4 DMZ. It arrived with Season 1 on November 6, 2026. The publisher describes it as a former GRANIT Arms black site on Hajin’s northern border. That is the confirmed scope: X01 is a separate DMZ map, not a district inside Hajin.

Because X01 is described as a separate black site rather than a Hajin district, do not carry over Hajin routes, key-door assumptions or threat ratings. The official material reviewed here establishes the map’s identity and access window; it does not publish a complete interactive layout, loot table or extraction map in the sources used for this page.

• Read Hajin’s regions and threats separately
• Compare Orders with Story Missions and other objectives

X01 access: Season 1 and the ended free trial

Season 1 went live on November 6, 2026 at 00:00 ET. A DMZ Free Trial ran from November 6 to November 11, 2026 and allowed access to both Hajin and X01. That trial has ended. After it, Modern Warfare 4 is still required to play DMZ; this page does not establish a permanent free-to-play offer.

If X01 is not visible, first confirm that your account owns Modern Warfare 4 on the platform you are using, then finish the current update and check the current Deploy flow for the X01 option. The access guide covers entitlement, installation and locked-mode checks in more detail.

• Check current access, platform and installation requirements

Season 1 features and X01 objectives

Season 1 adds new Orders and the Deep Vault. This page does not provide a complete step-by-step route for every X01 objective. Treat the in-game briefing and the current Orders page as the authority for the exact interaction, item or completion condition.

An Order name is not a route. If a guide or video describes a specific X01 door, vault entrance or loot spawn, check its game, mode, map and version before following it. This page does not repeat unverified coordinates or fixed rewards.

• Identify the objective type before following its marker
• Prepare an Operator and loadout before Ready Up

X01 is on Hajin’s northern border, but it is not Hajin

The official description places X01 on Hajin’s northern border. That geographic note explains the relationship between the two maps; it does not mean you can walk from Hajin into X01 during a deployment. Choose the map available in the current deployment flow rather than planning a border crossing.

Do not transfer a Hajin grid reference, Police Station Armory Key route or regional threat rating to X01. Shared DMZ systems such as the FOB, Operators and exfil remain relevant, but each map’s locations and objective steps need their own current-version evidence.

• Use Hajin grids and landmarks only on Hajin
• Review the standard exfil sequence and loss rules

Prepare for an X01 run

Prepare X01 like any other DMZ deployment, but confirm the map-specific objective before you leave the FOB. Recruit an Active Duty Operator, choose a loadout that supports the current Order, and agree on a stop condition with your squad. If you usually play on Hajin, treat X01 as a new map and relearn its landmarks from the current deployment rather than relying on familiar routes. A black-site theme is not evidence of a fixed enemy layout or guaranteed high-tier loot.

• Confirm the current X01 map selection and the active Order before Ready Up.
• Check the Operator, loadout and Squad Fill settings; Solo does not create a private PvE session.
• Decide which item or objective must be extracted, then protect it with the available Secure Slots.
• Recheck the exit after useful progress; a longer run keeps recovered gear at risk.

• Check FOB storage and station unlocks
• Review Operator Traits and MIA recovery
• Plan the return before the run

What to verify in the current build

The November 9, 2026 patch notes include X01 fixes. If a prompt, door or objective behaves differently from a launch-day clip, check the current patch level before repeating the old step. When comparing footage, record the patch version and the map name shown in the capture; a clip recorded before the November 9 fixes may show behavior that has since changed. This page is based on the official Season 1 announcement, the official free-trial post and the patch notes; it is not a first-hand playtest.

No exact X01 loot spawn, key-door location, boss route or exfil coordinate is published here. Those details need current-version evidence, and a familiar DMZ object or UI label is not enough to transfer a route from Hajin or an older DMZ map.

X01 coverage status

This reference covers X01’s identity, Season 1 access and preparation boundaries. It does not yet provide a complete map, a key list or a step-by-step Deep Vault walkthrough. The wiki will add a route only when current-version evidence supports the steps; missing details are left unverified rather than filled with guesses.

An X01 route page would need current-version evidence for the map, the named objective, the entrance or interaction, and the exit. Until those details are verified, this page keeps the confirmed Season 1 scope and points to the system guides instead of presenting a guessed walkthrough.
