The Cold War Zombies intel locations in Firebase Z are a challenge on the newest Call of Duty Zombies map. Documents, Radio Transmissions, Audio logs and more add to an experience that already comes with a lot to do. This Intel, which consists of collectibles that are scattered around the map, might be causing some issues. 

In total, there are 76 pieces of Cold War Zombies intel in Firebase Z to collect. They require you to complete trials, defeat enemies, or discover them by completing the map’s Easter Egg. In this guide, we’ll walk you through finding all 76 pieces of Intel on the Firebase Z map. Do keep in mind, it’s highly recommended to be familiar with constructing the Wonder Weapon, along with the main Easter Egg, as we’ll be referencing both of those objectives multiple times throughout this guide.

Cold War Zombies Dark Aether intel - 16 pieces

Dark Aether Documents - 10 total

The nice thing about the Dark Aether documents is that they’re relatively straightforward to collect. All you have to do is complete Intel Trials, which are initiated from the computer in the main area of Firebase Z (by the teleporter).

You can earn up to three Dark Aether documents per match, so it’ll take you four matches total to earn all of them. Just make sure you complete the trials that are specifically for Intel, as the other ones won’t count.

Once you complete an Intel Trial, head back to the computer to collect it. Repeat this nine more times to collect all of them.

Dark Aether Radio Transmission - 1 total

This one is also found at the Trial computer in the main area of Firebase Z.

Dark Aether Artifact - 1 total

To gather all of the Requiem Transmissions, simply visit the upper floor of the Data Center and interact with the radio on the table across from one of the Aether reactors. You can only collect a Transmission once per match, so you’ll need to visit this spot 11 more times to gather all of them.

Three of the Requiem documents are dropped from Mimics. There are four in total, and the final one is found inside a safe in the Colonel’s Office. 

To acquire it, you need to complete a side Easter Egg. Perform all the steps of the main Easter Egg until you reach the point with the Essence Traps. Use the Essence Trap to capture a zombie and deliver it to a table in the Field Hospital.

Then, you need to find Sergei's head, which spawns in locations across each defense area, Scorched Defense, Jungle Defense, and Rocky Defense. The head can spawn in two possible locations across each area, so look around at each until it appears.

Take the head back to the table in the Field Hospital and you’ll be given a code, which can be used to open the safe in the Colonel’s Office, giving you the final document and a random perk.

Requiem Artifacts - 4 total

The Requiem Artifacts are all gathered as you build the Firebase Z Wonder Weapon, which we go into more detail about there. You need to collect the materials needed to construct the weapon and each main component rewards you with an Artifact.
