Infinity Ward’s latest hotfix strips DMZ of its guaranteed UAV Towers and gives players twice as much time to hide from scans.
Key points
- UAV Towers now spawn randomly and 40 % less frequently, ending the guarantee of a tower at every POI.
- Multiple towers can no longer appear in the same area, except in Deadtown where they remain essential for progression.
- The Sedative Inhaler’s duration has been increased to 120 seconds, doubling the time players can hide from UAV scans.
- A future update will make the Sedative Inhaler work against trait‑upgraded UAV Towers, but that change is not yet live.
A fresh hotfix for Call of Duty: Modern Warfare 4’s extraction mode DMZ has altered one of the mode’s most contentious mechanics, according to the patch notes published by Eurogamer (https://www.eurogamer.net/call-of-duty-modern-warfare-4-dmz-uav-tower-nerf). UAV Towers, which previously spawned at every Point of Interest, now appear according to a randomised algorithm and 40 percent fewer of them will generate across the map.
The change also prevents multiple towers from occupying the same area, with the sole exception of the Deadtown zone, which still requires several towers for DMZ Order progression. By removing the guarantee of a tower at each POI, the update curtails a tactic many aggressive players have relied on—spawning, activating every nearby tower, and instantly revealing enemy movements.
UAV Tower spawn logic overhauled
A character trait that previously stopped UAV Towers from expiring, keeping scans active for the entire match, is slated for adjustment. Infinity Ward confirmed that the Sedative Inhaler, which hides a player from UAV scans, will be made compatible with those upgraded towers, though that fix is expected later in Season 1.
In the meantime, the patch doubles the Sedative Inhaler’s active time from 60 to 120 seconds, giving players a longer window to stay undetected while the broader balance changes roll out. The update arrives amid ongoing discussion about DMZ’s matchmaking, including reports of a separate pool for Story Missions that isolates solo players.
Sedative Inhaler duration doubled
The community’s reaction has been mixed; some welcome the reduced predictability of UAV coverage, while others note that the longer Inhaler duration may shift the balance toward stealth‑focused playstyles.
Reader questions
Will UAV Towers still appear in every part of the DMZ map?
No. The hotfix randomises tower spawns and reduces their overall frequency by 40 %, so many POIs will no longer have a tower.
How long does the Sedative Inhaler now protect me from UAV scans?
The Inhaler now lasts 120 seconds, up from the previous 60‑second duration.
When will the Sedative Inhaler work against trait‑upgraded UAV Towers?
Infinity Ward has said the compatibility will arrive later in Season 1, but no exact date has been given.
