How to Complete Blindness in MW4 DMZ (Print 4 Flash Grenades, Kill 8 Flashed Enemies)

BLINDNESS, the Flash Grenade order in Call of Duty: Modern Warfare 4’s DMZ, has two stages: one at your base and another in the field. It is order 01 on the CH. HUMAN INTEL 2/2 page of DMZ Orders; the page number shown depends on how many pages you have already finished. The Underground chapter’s 2/2 page holds Death From Above instead. Complete “Print 4 Flash Grenades” first; only then does “Kill 8 Flashed Enemies” become active.

Quick answer: At the FOB, access the 3D PRINTER, select FLASH under TACTICALS and print four. Deploy, blind soldiers, then kill eight of them. The 14th Political Prison has enough targets.

Flash Grenade order objectives and cost

The order has two objectives, and the game shows them one at a time. The tracker counts your progress on each one.

Objective	Counter	Where you do it
Print 4 Flash Grenades	0/4	FOB 3D printer
Kill 8 Flashed Enemies	x/8	During a deployment

A single Flash requires 10 Synthetics and 10 Chemicals, making the total for four 40 of each material. Check your amounts in the printer screen’s bottom-left, beside SYNTHETICS, ELECTRONICS, CHEMICALS and METALS. If you lack either material, gather more Synthetics or Chemicals during a deployment before printing.

Print 4 Flash Grenades at the FOB 3D printer

At the FOB, interact with the 3D printer. Its screen is headed 3D PRINTER.

Select TACTICALS from the left-hand column. The menu lists FLASH, STIM, CONCUSSION GRENADE, HEARTBEAT SENSOR, SMOKE GRENADE, DECOY GRENADE, SNAPSHOT GRENADE and SHOCK STICK, as well as SCREAMER MINE.

Select FLASH. Its card is marked COMMON and reads “Creates a blinding flash that disorients nearby personnel.” The card also shows the recipe cost and a Max Printable figure, which tells you how many grenades your materials can cover.

Use PRINT TO OPERATOR to equip the grenade immediately, or choose PRINT TO STASH to save it. TRACK RECIPE is also available, and the screen displays how many of that item are in your Stash.

Keep printing until the order reads 4/4. That completes the first objective, and “Kill 8 Flashed Enemies” takes its place.

The objective is “Print 4 Flash Grenades”, so use the printer to complete it.

Kill 8 Flashed Enemies at the 14th Political Prison

A kill registers only during the target’s flash-blindness. Toss the grenade, then fire before the targets recover.

Equip the Flash grenades as your tactical and deploy. If you printed them to your stash, add them to your loadout before you go in.

Head to the 14th Political Prison, in the map’s north-western region. Its threat level is HIGH. Soldiers occupy the yards among the wooden huts and the interiors of the warehouses, giving you enough for all eight kills in one visit.

Throw a Flash into a group of soldiers, then kill them before they recover. Watch the counter on the right side of the screen to confirm each kill counted.

In warehouse fights, send a Flash through the doorway to blind the occupants, then eliminate them. Soldiers in one warehouse may be enough to raise the counter from 5/8 to 8/8.

When the counter reaches 8/8, the objective is marked complete. The next objective on the page then appears: “Collect a Dynamic Op Phone”, the first line of order 02, Payment Due (see how Dynamic Ops work).
