All Intel Locations On Mauer Der Toten - Black Ops Cold War: Zombies

After the Outbreak prologue easter egg, we continue the Dark Aether story in Mauer Der Toten. Mauer Der Toten has a lot to offer in terms of story content and the main easter egg.

Mauer Der Toten contains 48 new Intel, which are spread all over the map. Some of these Intel have fixed locations, while some can only be obtained by killing the elite zombies such as the Disciples and Krasny Soldat. You can also collect some Intel by doing the trials from the trial computer located on West Berlin Street.

The Intel helps you understand the Dark Aether story in detail from the perspective of the four central "teams" involved in the story: Requiem, Omega, Maxis, and Dark Aether. Below, we have listed the locations of all the Intel and how you can obtain them. Although there are four teams, you only have Intel for Requiem, Omega, and Maxis on Mauer Der Toten.

Mauer Der Toten was introduced in Season 4 Reloaded, where the Intel hunting begins for you. We will update the article with more Intel in case any more are added in the future seasons.


If you haven't already collected the Intel on other maps such as Firebase Z and Die Maschine, then do so as you won't be able to collect the radio transmissions for some if you haven't collected the previous radio transmissions. Don't forget to collect the Intel on Outbreak too.

  1. Hi Hassan,

    Love the site! It is my go-to for all things COD Zombies.

    Have you heard about the Omega audio log "The Turn" on top of the guard tower bugging? I can see it and shoot it, but it refuses to come down. I've tried at different intervals in the game (pre-PAP, post PAP, w/ Wonder Weapon, sniper w/ scope, etc) but nothing works.

    Thanks for the help.

    1. Hi Chomper!

      Thanks for your positive feedback. Yes, I'm aware of that issue and ran into it myself as well. I suggest you keep shooting it at least 4-5 times. I had to shoot it down multiple times with a sniper rifle for it to fall to the ground.

      It seems that the hitbox is not correctly registered for this audio log. Might want to shift your cross-hair to the sides also. For me, I shot dead center but multiple times. I used a Stoner 63 LMG off the wall buy and kept shooting until it fell.

      And if you haven't already, try shooting it from the Destroyed Penthouse. It gives a better angle!
