How to Find Comms Modules in Modern Warfare 4 DMZ

Acquiring comms modules in Call of Duty: Modern Warfare 4's DMZ mode can be a significant challenge, as this high-tier crafting material is difficult to locate without knowing where to search. These modules are crucial for unlocking the ability to print uncommon crafting ingredients, expanding weapon storage, and creating equipment such as fulton drop markers. While epic ingredient printing can eventually allow you to craft them, this is only possible after obtaining even rarer items.

Best Locations for Comms Modules

Comms modules can appear in various locations across the DMZ map. Among the most reliable spots are the server rooms within the Netshin Tech Complex, a row of buildings situated east of Deadtown and adjacent to the river, and DBN Headquarters within The Grid. Choosing the "Operation Grid Assault" story mission can place you conveniently near DBN Headquarters, where searching the computer-filled rooms upstairs is a good strategy for finding a comms module. This area also provides proximity to the Netshin Tech Complex.

Additionally, downed drones scattered throughout Hajin may contain comms modules, though their spawns are random. The Cheonwang Peak Array is another potential source, but it is heavily guarded and presents a significant challenge, particularly for solo players.
