Materials that drop from bosses
The rarest ingredients come from the Commanders, the roaming bosses: Experimental Compounds, Prototype RF Module, Military Composites and Nano-Structured Alloy. Where players have run into each Commander, and how the Boss Board works, is in our MW4 DMZ bosses list. A Commander kill pays DMZ XP, and getting out afterwards brings the ingredients home.
Print what you cannot find
14 ingredients have a print recipe at the 3D Printer, unlocked by the Ingredient Printing upgrade for their rarity (what each upgrade costs is in our 3D Printer upgrades list). What each print costs, and every recipe these ingredients go into, is in our 3D Printer recipe list. CPUs and Comms Modules have a page about the buildings players loot them in, the Deadtown hillside facade buildings.
Questions
Where do you find crafting materials in MW4 DMZ?
At the 3D Printer, open the recipe you want and pick Ingredient Locations: the game names where each ingredient it needs is found, such as server rooms, hospitals or toolboxes. Every hint is listed on this page with the places it names.
Which DMZ ingredients drop from bosses?
Experimental Compounds (Commanders), Prototype RF Module (Deathstalker), Military Composites (Colossus) and Nano-Structured Alloy (Main NK Battle Tank). The Commanders roam Hajin; where they are reported is in our bosses list.
Can you print 3D Printer ingredients in DMZ?
Yes, 14 of them, once you buy the Ingredient Printing upgrade for their rarity. Printing one costs base resources and, for the rarer ones, other ingredients.
