Decryption DMZ Mission Guide

In Season 2 of Call of Duty: Warzone 2 DMZ, Decryption is a Tier 4 Crown Faction mission. This mission requires you to collect and extract Encrypted Hard Drives specifically on the Building 21 map. Here are some of the best locations where you can find these items in abundance.

Decryption Mission DMZ

• Extract 10 Encrypted Hard Drives from Building 21.

The Building 21 map is only available in DMZ during weekends. To deploy into the secure facility, you'll need a DRC Building 21 Access Card. These keys can be obtained by purchasing them from shops or looting supply drops on Ashika Island and Al Mazrah. Deploy onto this map and start looking for and collecting Encrypted Hard Drives, which are high-tier loot items worth $5000.

Office Storage on the second floor is the best area in Building 21 where you can find multiple Encrypted Hard Drives placed inside computers and office cabinets. The second level can be reached via stairwell doors A2, B2, C2, and D2 located on all corners of the facility. The Lobby area by the elevator also has some computers that you can loot. Furthermore, you can head over to the third floor and take out the Wheelson, which alone drops two or more Encrypted Hard Drives.

The third floor also has a Core Lab area where you may find some Encrypted Hard Drives placed on counters. Once you're satisfied with the loot you have, exfil using one of the marked extraction elevators that appear during late-match. Make more required trips to Building 21 to extract the item you need for this mission. It may be challenging because of enemy squads and armored guards, but easily doable if you proceed with caution.
