MW4 DMZ progression: what carries over to Multiplayer?

Which progress carries across?

Progress	What carries over?	What to check
Overall Player Progression	DMZ XP also advances the overall 1–55 track	Your overall level in Career
DMZ level	Separate 1–70 track; MP and Warzone XP do not raise it	DMZ level rewards
Weapon levels	Shared across DMZ, Multiplayer and Warzone	The weapon’s level, rather than your player level
Attachment unlocks	Shared across modes	Whether that attachment fits the weapon
DMZ purchase access	Specific developer guidance requires extracting the corresponding Manual	The requirement at your FOB Gunsmith

As of October 21, Warzone integration is scheduled for Season 1 on November 6. The shared-progression rule includes Warzone, but that does not mean the MW4 integration is already live.

Why is my weapon leveled but still locked at the FOB?

Weapon XP and permission to buy another copy serve different purposes. You can bring home a looted gun, level it and unlock attachments without that physical instance becoming an unlimited replacement supply.

The Weapon Manual guide explains the extraction unlock. Official wording on purchase access differs: the developer’s detailed answer separates it from MP unlocks, while the arsenal overview describes broader cross-mode availability. Follow the requirement displayed by your Gunsmith until that difference is resolved.

Which level should you work on?

If you need a DMZ station or deployment feature, use the DMZ level rewards rather than an MP level table. If you need attachments, use the weapon’s progression screen.

For Operator traits, use the skill trees guide. For resets, consult the Prestige systems guide: Player, Weapon and Operator Prestige are different decisions. Do not use one track’s reset rules to predict another’s.
