What is X01 in Modern Warfare 4 DMZ? X01 is a new enclosed Black Site reached through the Hajin Exclusion Zone in MW4 Season 1, starting November 6, 2026. It has cargo and vehicle areas, underground laboratories, production facilities, connected tunnels and a sealed Deep Vault. The main challenge is not simply finding loot: your squad must handle dangerous enemies, follow new Ghost Orders and leave before the facility closes extraction options.
For a first deployment, bring weapons you already know, choose one objective, identify a fallback route and keep your extraction plan flexible. This guide uses Activision’s official Season 1 briefing and separates confirmed information from tactical advice for the first run. Exact floor maps, locked-room solutions, boss spawn points and loot tables are not part of the published X01 briefing.
MW4 X01 Black Site: Quick Facts
MW4 X01 First Deployment Checklist
The easiest way to waste a trip into an unfamiliar facility is to enter without deciding what matters most. Before you queue for DMZ, pick a job you can recognize in the mission screen: explore, work on a Ghost Order, hunt an event Commander or extract useful gear. The same deployment may offer several opportunities, but your first priority should be one objective you can finish safely.
| Before you enter | Why it matters | Action to take |
|---|---|---|
| Choose one primary goal | Boss hunting, exploration and extraction involve different risks. | Read your active DMZ Order or Event entry before loading in. |
| Bring a familiar weapon | Tunnels and open bays can demand different engagement distances. | Use a reliable primary weapon and a backup suited to close spaces. |
| Plan for armor and recovery | Heavy enemy resistance can drain supplies before you reach the objective. | Use armor and recovery gear available in your loadout; avoid relying on an unknown rare drop. |
| Agree on roles | Multi-floor movement makes it easy for a squad to split. | Assign a route caller, a rear guard and someone watching objective progress. |
| Keep a fallback | The facility is announced to close off some escape options. | Decide when to abandon optional loot and prioritize an active exfil. |
If your preferred gun still lacks useful attachments, prepare it before committing to the deeper facility. You can work through the MW4 Weapon Leveling Guide, or compare a weapon-leveling service. Multiplayer preparation and X01 mission completion are different jobs.
Get Your Weapons Ready Before X01
A reliable gun and a clear objective give you a better starting point than an improvised loadout. Weapon preparation can happen outside DMZ, but an X01 Order or extraction must still be completed in DMZ.
X01 Map Layout: Confirmed Areas and How to Approach Them
X01 is described as a multi-floor indoor complex with linked tunnels and chambers. Activision has named several broad areas, but has not supplied a verified player route connecting them. Treat the table below as an orientation guide, not a room-by-room floor plan or a claim about enemy spawn locations.
| Announced area | Why to pay attention | First-run decision |
|---|---|---|
| Cargo bays and vehicle depots | Large spaces may offer several approaches and expose your team to different angles. | Advance from cover to cover and keep teammates in sight. |
| Connecting corridors and tunnels | Long indoor passages can limit escape options if a fight starts behind you. | Check the return path at each junction before moving deeper. |
| Underground laboratories | The facility includes research spaces below ground, with unknown threats and equipment. | Avoid making a full commitment without supplies or an exit plan. |
| Production lines | The weapons facility contains assembly areas and linking chambers. | Use the active objective marker to choose the right section, rather than searching every room. |
| Sealed Deep Vault | The official briefing mentions the Deep Vault but does not publish its entry procedure. | Treat vault access as a separate objective only if the live mission provides its steps. |
| Multi-floor traversals | Vertical routes can separate a squad and change what counts as nearby. | Call out floors and regroup before hard fights. |
The site is linked to a former GRANIT Arms black facility near Hajin. An infiltration point is announced through the surrounding Exclusion Zone; that does not mean the X01 interior is just another section of a normal open-air Hajin patrol. Plan for enclosed navigation and extraction pressure.
How to Plan Your First X01 Run: Eight Useful Decisions
This route is a decision sequence, not a fictional map path. It works even when the live facility has unknown doors, hazards or several valid objectives.
- Check the active mission before deployment. Decide whether you want a Ghost Order, event item, exploration or a gear extraction. Do not assume every unlock comes from the same mission.
- Enter with a working loadout. Use weapons you can control reliably; prioritize survival and extraction over trying an unfamiliar attachment setup.
- Identify the nearest safe fallback. As you enter the facility, remember how to return toward a known route. The facility is announced to close some escape points.
- Use Ghost’s updates to set direction. Ghost is the X01 Watcher and provides route and threat information as areas become available. Let those updates guide progress instead of inventing a fixed vault path.
- Move through one section at a time. In multi-floor corridors, keep the squad close and avoid opening two separate fights without a reason.
- Commit to a boss only when ready. If your objective targets The Captain, check your team’s available ammunition, armor and escape route first. Other named enemies may belong to broader DMZ deployments.
- Confirm the item or objective counter. For an Event, earning a kill and extracting its designated part are not the same step. Look for the required carried item before leaving.
- Exfil while your exit remains practical. If routes become inaccessible or the situation deteriorates, stop chasing optional rooms. A clean extraction with the main objective is better than losing it to extra loot.
Use post-run results to decide what to change for your next deployment. If you died without reaching the objective, simplify the route and carry more reliable supplies. If you completed the task but failed to extract, prioritize exfil earlier rather than repeating the same late push.
MW4 X01 Ghost Orders: What the Watcher Does
New X01 Orders are guided by Ghost, who acts as the Watcher for this facility. Activision says he tracks the team’s route, warns of threats and offers clues as newly accessible areas open. Multiple pages of Orders are planned. The exact mission names, item quantities and unlock prerequisites have not all been published in the Season 1 briefing.
How to keep an Order from getting lost in the noise
- Read the exact objective text and whether it asks for exploration, combat, recovery or extraction.
- When Ghost reports a new area or threat, compare it with the current task instead of assuming it begins a new mission.
- Keep one player responsible for checking objective progress; the rest of the squad can focus on the route and threats.
- Before the last detour, ask whether the Order needs a final extraction or a carried item. A completed firefight may not finish the operation.
Do not confuse Ghost Orders with DMZ Mastery Camo challenges. An Order might reward equipment or mission progression, while Chiral, Ripple Tide and Helio belong to their own weapon camo system. Check which progress bar you are actually advancing.
X01 Enemies and Named Bosses: What Is Confirmed
The announcement identifies resistance from the 100 Spirits NK Faction and warns about troops, specialists and more dangerous interior enemies. It also introduces a broader DMZ Boss Board. Do not treat a listed Boss Board name as proof that the enemy has a fixed spawn inside X01.
| Threat or target | Officially announced information | What to plan for |
|---|---|---|
| 100 Spirits troops and specialists | Enemies are active around X01; heavy resistance is expected. | Avoid prolonged fights that consume all your recovery supplies. |
| The Captain | A Juggernaut Commander supported by an elite guard; X01 Threat Briefing target. | Set a retreat path and be ready to extract the required helmet parts. |
| Autonomous Wheelson | A patrolling Commander named in the broader DMZ Boss Board. | Do not assume it shares The Captain’s location or event requirements. |
| Tae-Hyun (Knuckle) | Lieutenant named as a future Boss Board target. | Use the actual Boss Board for deployment-specific directions. |
| Chol-Min (The Wrench) | Another named Lieutenant. | Distinguish this target from the X01 Captain event before entering. |
| Unrevealed enemies | Activision keeps several X01 threats classified. | Respond to what the live encounter shows rather than using made-up health values or abilities. |
Threat Briefing and Resupply Run: Choosing a Season 1 DMZ Event
Season 1 includes events across Hajin and X01. The two announced Threat Briefings have different locations and collection goals, and extracting the requested part is central to the event loop. Activision also says all squad members get credit when one member successfully exfils with a Commander part.
| Activity | Location / task | What progress depends on |
|---|---|---|
| Threat Briefing: The Captain | Enter X01, fight The Captain and collect sections of his Juggernaut helmet. | Successfully extract with the relevant helmet parts. |
| Threat Briefing: Battle Tank | Fight a North Korean tank in Hajin and remove tank parts. | Only one tank part per deployment is specified; extract and accumulate parts across deployments. |
| Resupply Run | Locate requested items at different POIs and trade them for valuable supplies. | Complete the item request and exchange it for eligible gear such as Self Revives or 3-Plate Carriers. |
When to target The Captain
Choose the Captain event if you and your squad are equipped for a Juggernaut and escort threat, and you have enough time left to extract. The official briefing does not disclose a fixed spawn room, exact helmet-piece count per run or guaranteed weapon reward. Check the live Event entry for the target and the current reward track before committing.
When the Battle Tank is the wrong target
The tank objective is announced for Hajin, not the X01 interior. If your target is a tank part, do not spend the deployment searching X01 tunnels. The announced one-part-per-deployment rule also makes it a multi-run activity, not a shortcut you can finish by collecting several parts in one visit.
Resupply Run is useful for players who want gear rather than a Boss fight, but its exact requested items can differ. Look at the active exchange list and avoid filling your inventory with objects that are not part of that request.
How to Prepare for Extraction When X01 Starts Closing Routes
Activision warns that the facility can close off extraction points as an operation progresses. That is the most important reason to treat X01 differently from an ordinary loot sweep. The announcement does not reveal exact closure timers, all exit locations or a universal sequence for opening them.
| Situation | Safer decision | Common mistake |
|---|---|---|
| The Order is complete and the team has the required item. | Start moving toward an available extraction without an optional boss detour. | Assuming the remaining escape options will stay open. |
| A teammate is separated on a different floor. | Regroup at a known junction before pushing into another room. | Chasing two objectives across different levels. |
| A Commander drops an event part. | Confirm who carries the part and keep that player protected. | Leaving the area without checking the objective item. |
| The intended route becomes unsafe or inaccessible. | Use another route shown by your current map and Ghost updates. | Following a memorized path even when the operation changes. |
| The squad is low on supplies. | Extract a smaller win instead of forcing the Deep Vault. | Trading a guaranteed completed objective for uncertain extra loot. |
If an exit or Order asks for a special interaction, follow that in-game prompt. The public announcement establishes changing extraction conditions, but not a complete list of door switches, access cards or exfil codes.
X01 Solo or Squad: Which Approach Is Better for Your Goal?
The briefing stresses multi-floor routes, powerful enemies and squad coordination. That makes team play a sensible starting choice for a first visit. A solo run may still be useful for reconnaissance, but a long Commander fight is harder to manage without someone covering your rear or supporting extraction. These are planning recommendations, not published difficulty multipliers.
| Your goal | Suggested approach | Reason |
|---|---|---|
| See the first rooms and learn the route | Careful solo exploration or small squad | Prioritize mapping a return path and ending the run safely. |
| Progress Ghost Orders | Coordinated squad | One member can track the task while others protect the route. |
| Hunt The Captain and extract parts | Prepared squad | The Juggernaut and guards create a higher-risk task; squad extraction credit is announced. |
| Build a Helio camo plan | Follow the DMZ camo requirements | X01 exploration alone is not proof of Mastery progress. |
X01 Rewards vs Weapon XP vs Helio: Do Not Mix the Counters
The X01 facility offers several types of progress, but none should be treated as interchangeable. Ghost Orders and their rewards are mission-specific. Threat Briefing depends on its target item and exfil. Weapon XP improves an equipped gun when eligible activities award it. DMZ Mastery is tracked by the separate camo objectives on your weapons.
For the overall Season 1 roadmap, including free Battle Pass weapons and other events, use the MW4 Season 1 Guide. For Helio’s specific progression, follow our MW4 DMZ Camo Guide. If you want a selected weapon leveled before a deployment, compare the MW4 Weapon Leveling options. Hosted MW4 Bot Lobbies are self-play Multiplayer sessions, not a substitute for X01 extraction or a Commander event.
Five Mistakes to Avoid on Your First X01 Deployment
- Entering without an objective. A route that works for reconnaissance may fail a mission that asks for extraction with a particular item.
- Using a claimed boss location from an unverified map. The pre-season briefing does not publish exact rooms for every boss or Lieutenant.
- Overcommitting to the Deep Vault. Its entry requirements and full reward list are not announced; a completed Order can be worth more than an uncertain detour.
- Splitting across floors during a firefight. Multi-level corridors create separation and make it harder to support a teammate.
- Confusing ordinary kills with event completion. For Threat Briefing, a Commander part must be successfully extracted; do not assume eliminating the target finishes the reward track.
For the first run, prioritize a known goal and a practical exfil. You can return for rare equipment and deeper objectives once you understand how the live facility changes.
