X01 has become one of the more challenging areas in Modern Warfare 4 DMZ, especially for squads balancing PvP encounters with objective progression. However, some of its early mechanics did not work as intended. The November 7 update addressed several issues involving Bounty Level increases, Vault interactions, and mission progression.
For players collecting MW4 DMZ Items inside X01, these fixes matter because a successful run depends on more than winning gunfights. Understanding objective order, managing squad encounters, and avoiding progression problems can make a major difference when carrying valuable equipment.
X01 Bounty Level: What Changed?
One important fix addresses how player eliminations affect Bounty Level in X01. Previously, killing Operators could increase the level more than intended. The November 7 update corrected this behavior.
This does not mean PvP kills no longer affect Bounty Level. Instead, the excessive increase was corrected so the system works closer to its intended behavior.
For squads exploring X01, the practical lesson is to think carefully before starting unnecessary fights.
- Avoid engaging another squad without a clear reason.
- Consider whether a fight is worth the ammunition and equipment it may consume.
- Keep track of your Bounty Level during longer deployments.
- Prioritize mission objectives when your inventory contains valuable loot.
PvP can still be part of your strategy, but chasing every nearby encounter is not always the best way to complete an X01 run.
Vault Defense: Complete the Objectives in the Correct Order
The November 7 update also changed the Vault Defend interaction. It is now available only after the Vault Door has been opened.
This is an important distinction for players who previously encountered an unavailable interaction while working through the objective.
When approaching the Vault sequence, focus on the required steps rather than repeatedly trying to activate the defense interaction too early:
- Follow the active Vault objective.
- Complete the required steps to open the Vault Door.
- Once the door is open, check for the Vault Defend interaction.
- Continue with the available objective and watch for enemy activity.
The update also adjusted the location of the Power On interaction to prevent its marker from overlapping with the Vault Door objective. If you are following an older route, the marker may not appear exactly where you expect. Use the current in-game objective indicator instead of relying entirely on outdated positioning.
Operation Fallen Ember Mission Progression Fix
Another important correction affects Operation Fallen Ember. Destroying a boat before completing the second-to-last Story Mission objective could previously prevent mission progression.
This is particularly relevant to squads that prefer clearing vehicles or threats as soon as they appear.
To avoid unnecessary complications:
- Check the active mission objective before destroying boats.
- Complete the required objective sequence first.
- Avoid removing mission-related vehicles before the game registers the relevant step.
- Confirm that the objective updates before moving to the next area.
The issue has been addressed in the November 7 update, but following the intended objective order remains a sensible approach for mission runs.
Other X01 Combat Fixes Worth Knowing
The update also addresses several combat-related issues that could affect difficult encounters.
| Fixed Issue | What It Means for Players |
|---|---|
| Captain and Colossus could eliminate revivable players in Last Stand | Downed players who were still eligible for revival should no longer be eliminated incorrectly by these enemies |
| Wheelson Commander turret audio was missing | Turret movement sounds should provide more reliable audio information |
| Wheelson turrets could continue rotating after DDoS or Shock Stick effects | Disabling these systems should behave more consistently |
These changes are especially useful when fighting in confined areas. Audio cues can help squads understand enemy movement, while more consistent Last Stand behavior makes team coordination less frustrating.
How to Prepare for Your Next X01 Deployment
A good X01 deployment should have a clear objective. Before entering, make sure your squad knows whether the priority is completing Orders, progressing through the Vault, or collecting valuable equipment.
Prepare your loadout: Bring reliable weapons, sufficient ammunition, armor, and healing supplies. Avoid carrying equipment that leaves no room for important loot.
Assign squad roles: One player can focus on objective interactions while teammates watch nearby entrances and possible enemy approaches.
Watch your mission progress: Check that each objective registers before moving away. This is particularly important during multi-stage Story Missions.
Players who also want to make their Multiplayer progression more efficient can explore Bot Lobbies MW4 giving them another way to work toward selected unlock goals while keeping their DMZ deployments focused on objectives and valuable loot.
The November 7 fixes make several parts of X01 more consistent, particularly PvP Bounty Level progression and the Vault objective sequence. Operation Fallen Ember also benefits from a correction to its mission progression issue.
For your next deployment, focus on completing objectives in order, avoid unnecessary squad fights, and pay attention to updated interaction markers. These small adjustments can help prevent wasted deployments and make your time in X01 more productive.
