❗️ Call of Duty: #ModernWarfare4 | #DMZ Early Access We're investigating an issue preventing some DMZ players from entering Prestige on their Active Duty Operators. While we work on a fix, players can get around this issue by equipping rare (blue) weapons with only 3 attachment slots (weapons which have never had 4 or more attachments on them before) to complete the Operator Prestige requirement.

🛠️ Call of Duty: #ModernWarfare4 | #DMZ Early Access This issue has been resolved.
📢 Call of Duty: #ModernWarfare4 | #DMZ Early Access We're investigating an issue impacting a small number of players who immediately sold their starting equipment (including Med Kits) or dismissed their Active Duty Operator with the starting equipment equipped when entering the FOB for the first time. This can result in a soft lock on DMZ Orders and deployment. While we work on a fix, players can workaround this by joining on a friend and deploying into DMZ. Progress will be restored once you enter Hajin.
