Secrets
Verified hidden stashes, rooms, and Parkour-only routes in MW4 DMZ. Parkour pays — you will find secrets. Every entry here is from our own runs, on-screen evidence, or two independent sources.

Open area →On the north side of Production Assembly, behind a yellow cart.
More secrets coming
We will add parkour-only routes and hidden rooms when we have a firsthand clip or two independent sources. Do not treat unverified map rumors as facts.
High-value loot without a key
Not every high-value loot location is accessible by key. Some require maneuvering or parkouring in. Every player on this map has to figure it out, and it is an easy way for solo players to grab valuable loot fast without burning a key.
The Wheelson
The Wheelson: use a proximity mine. One or two is all it takes to disable it.
The deep vault
The deep vault can open without a deep vault key, but you cannot activate the core room. The core room is unlocked by turning on the power with the Vault 301 key, which you get from defeating the Captain. The power switches are hidden behind keypad doors, so you need that Vault 301 key or equivalent to reach them.
