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.

Comms Modules are random loot. Focus on these three locations:
For most runs, start at Deadtown, move to Cheonwang if needed, and use Netshin as a higher-risk alternative.
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.
| Upgrade | Requirements |
|---|---|
| Uncommon Ingredient Printing | 50,000 Cash, 20 Biomaterials, 10 High-Tenacity Fibers, 5 Comms Modules |
| Epic Ingredient Printing | 100,000 Cash, 10 Binding Catalysts, 10 Printed Circuit Boards, 5 Military Composites |
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.
| Item or upgrade | Modules needed |
|---|---|
| Uncommon Ingredient Printing | 5 |
| Stash Weapon Upgrade I | 5 |
| Advanced UAV | 2 |
| Fulton Drop Marker | 3 |
| MIA Recovery Discount III | 10 |
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.
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.
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.
Where should I farm Comms Modules?
Start at Deadtown, then search Cheonwang Peak Array. Netshin Tech Complex is another option when the area is safe.
Can I print Comms Modules immediately?
No. You must unlock Epic Ingredient Printing first.
Does DMZ leveling reward Comms Modules?
No direct Comms Module reward is listed on the level track.
Should I sell extra modules?
Only after completing your priority upgrades and checking your remaining crafting needs.
Comms Modules are essential for unlocking key crafting upgrades in MW4 DMZ. Focus on Deadtown and Cheonwang Peak Array, save your first five modules for Uncommon Ingredient Printing, and prioritize Stash Weapon Upgrade I when you need more storage.
