Another week, another big change for COD: Modern Warfare 4's DMZ mode as a new patch nerfs UAV Towers to ensure players are not immediately visible to everyone, all the time

The Call of Duty: Modern Warfare 4 patches continue, with the latest delivering some big changes to the game's extraction mode DMZ. The latest hotfix introduced a key balance change to one of DMZ's most controversial mechanics: UAV Towers.

UAV Towers, previously guaranteed to spawn in every Point of Interest (POI) in the map, have now had their spawn logic randomised. Infinity Ward also reduced their spawn rate by 40 percent, meaning you're less likely to find them across the various regions of the map. As noted in the patch notes, that change also prevents multiple towers from spawning the same area. The only exception is the Deadtown area, which factors into DMZ Order progression and requires multiple towers.
