How to Get Comms Modules in MW4 DMZ

Comms Module is an Epic crafting ingredient in MW4 DMZ Items progression. It is required for important 3D Printer upgrades and equipment recipes. Since the first upgrades need five modules, save them instead of selling them for quick cash.

Where to Find Comms Modules

Comms Modules are random loot. Focus on these three locations:

1. Deadtown

• Search the light-blue hillside buildings near the river.
• Check upper-floor computers and the spaces under desks.
• If the buildings are empty, move to another location.

2. Cheonwang Peak Array

• Find the Data Farm.
• Search server racks and containers labeled SERVER BLADE.
• Check the second building if the first has limited loot.

3. Netshin Tech Complex

• Search the server room on the 14th floor of The Grid.
• Check the 15th floor if the area is safe.
• Avoid spending time clearing unrelated floors.

For most runs, start at Deadtown, move to Cheonwang if needed, and use Netshin as a higher-risk alternative.

Can You Craft Comms Modules?

Yes, but only after unlocking Epic Ingredient Printing. Each module costs 100 Electronics and 3 CPUs.

Your first five modules cannot be printed because Uncommon Ingredient Printing requires them to unlock the later crafting progression.

Uncommon Ingredient Printing unlocks six recipes, including Reactive Metals, Control

Epic Ingredient Printing is a separate, expensive upgrade. The starting bank cap is 100,000 DMZ Cash, so consider Bank Upgrade I if you need to save beyond that amount.

What Are Comms Modules Used For?

Stash Weapon Upgrade I adds six weapon slots. However, DMZ levels 35 and 60 also provide additional slots, so consider your progression before spending five modules.

Advanced UAV and Fulton Drop Marker require their recipes to be found and extracted before crafting. MIA Recovery Discount III is a later upgrade with additional material requirements.

Best Farming Route

• Check your stash and confirm how many modules you need.
• Search Deadtown’s upper-floor computers.
• Rotate to Cheonwang and inspect every SERVER BLADE container.
• Visit Netshin if the first two locations are empty and the area is safe.
• Secure your modules and extract as soon as possible.

Avoid repeatedly searching empty rooms. Rotating locations is usually more efficient than staying in one cleared area.

Players who want to improve other progression tasks can also explore CoD MW4 Bot Lobbies options, while farming the ingredients required for their current upgrades.

Should You Sell Comms Modules?

Usually, no. Save the first five for Uncommon Ingredient Printing and consider keeping another five for Stash Weapon Upgrade I.

After completing these upgrades, use extra modules for Advanced UAV, Fulton Drop Marker, or MIA Recovery Discount III, depending on your needs.
