Where Netshin Tech Complex is

In The Grid, the walled-off business district in Central Hajin City, on the former South Korean side.
At grid G6 on the Tac-Map: the key card for the armory in its towers names that square.
Activision describes it as a twin high-rise tech complex with red roofs, the most dangerous part of The Grid.
The DBN TV tower, the tallest building in Hajin, is in the same district.

Threat level at Netshin Tech Complex: Extreme. The rest of The Grid is Critical.

The Netshin Tech Complex server rooms

At the 3D Printer, every recipe has an Ingredient Locations button with a one-line hint for each ingredient. For the CPU and the Comms Module, it reads:

Found primarily in the Netshin Tech Complex server rooms, Cheonwang Peak Array server rooms, and Deadtown hillside facade buildings.

The hint names search areas, not fixed spawns, so search the server rooms inside the towers. The whole complex is Extreme threat, so go in with a full loadout and a way out planned.

Ingredient	Rarity and value
CPU	Rare, worth 500 DMZ Cash
Comms Module	Epic, worth 1,500 DMZ Cash

Comms Modules are the ones players need first: the Uncommon Ingredient Printing upgrade costs 50,000 DMZ Cash plus 20 Biomaterials, 10 High-Tenacity Fibers, 5 Comms Module, and Comms Modules can only be printed after Epic Ingredient Printing, from 100 Electronics, 3 CPU. Every recipe and upgrade that takes them is on our where to find Comms Modules page.

The other places the game names

Cheonwang Peak Array server rooms, at Cheonwang Peak Array: threat level Medium.
Deadtown hillside facade buildings, at Deadtown: threat level Low.

Netshin is the most dangerous of the three. Going for Comms Modules with a light loadout, the Deadtown blocks are the quieter choice; every other 3D Printer ingredient and where to find it is on our MW4 DMZ crafting materials page.

Keys for Netshin Tech Complex
