The latest DMZ update (season 4) introduces new features and content like the Phalanx faction.
The Forward Operating Base (FOB) serves as a central hub where players complete objectives to unlock upgrades.
This includes weapon slots, stash size increases, and access to new missions.
A new Mission Objectives menu allows players to track their faction missions, upgrades, challenges, and notes.
In addition, there are seasonal resets for key and mission item stashes.
However, active duty slots and contraband weapon inventories remain unaffected.
