Call of Duty: Black Ops Cold War Zombies’ latest Survival map is full of secrets to uncover, but for those that love the mode’s story, none are as exciting as the intel. Fortunately, Mauer Der Toten brings many new collectibles for Call of Duty: Black Ops Cold War fans to gather.

This time around, the intel is limited to Omega, Requiem, and the Dark Aether. Zombies protagonist Samantha Maxis gets no new intel this time around, so gamers will need to wait until Season 5 to learn more about her story. Still, there is a lot of interesting information about Omega and Requiem in this new batch of intel, with the Dark Aether also being fleshed out further. Outbreak gets some intel, too, which will be included at the end of this guide. For those interested, here are all the intel items in Season 4 Reloaded.

Kicking off the list is the villainous Omega Group. Given the fact that Mauer Der Toten’s main quest is about killing an Omega turncoat named Valentina, it makes sense that some of the intel focuses on the group. The locations are as follows.

• Omega Radio Transmissions - Military Tent: Players can collect an Omega Radio Transmission every match by interacting with the same box. This radio is located in the Military Tent right next to the Ghost Station staircase. The tent is found in the East Berlin Streets, across from the Electronics Shop where players get a tape for the new easter egg song.

• Mini-Boss Omega Documents: As always, these drop from special enemies and mini bosses like the Krasny Soldat and Mangler. 1-2 will drop every match.

• Omega Audio Log 1 - Sewer Access: In the room beyond the Armor Stand, players will find a suspicious wall. While this wall is broken in the main quest, the intel can be picked up earlier. It sits on the floor to the left of the stairs leading up to the wall.

• Omega Audio Log 2 - Blasted Suite: In the Blasted Suite, which players can zipline up to from the West Berlin street, this audio log sits under a bed. The zipline is to the left of the Trial machine.

• Omega Audio Log 3 - Department Store/Death Strip: If players zipline into the Department Store that holds Wunderfizz (directly across from the Blasted Suite), they can look out the window to find this piece of intel. It rests on top of the machine gun tower and can be shot down easily with a Sniper Rifle. It will fall into a crater on the left side of the Death Strip.

• Omega Artfact 1 - Battery: Acquired from Killing the Krasny Soldat. Needed to build Klaus.

• Omega Artifact 2 - Endstation Lure: Essentially the Essence Trap from Firebase Z’s quest, these are picked up during the main easter egg’s canister step.

With players finally being teased about the identity of the Requiem Director, gamers should learn who is in command of Weaver and the other agents in the next map. With the most likely candidate being Eddie, it should be exciting to see his role in the narrative. Until then, though, players can collect Requiem intel to keep busy.

• Mini-Boss Requiem Documents: Like with the Zombies intel in other Seasons, these are dropped randomly from special or elite Zombies. One or two will drop per game.

• Requiem Document 1 - Ghost Station: Picked up on the train during the main quest.

• Requiem Documents 2-4 - Safe House: These will pop up during the main quest as players are cycling through the computer screens in the Safe house.

• Requiem Audio Log 1 - Ghost Station: On a pillar directly across from the Mule Kick machine.

• Requiem Audio Log 2 - Safe House: On a table directly to the right from where Klaus sits. It is to the left of the door that leads out of the Safe House.

• Requiem Audio Log 3 - Safe House: This only spawns after building Klaus. It will be in a locker to the left of the Safe House ammo crate.

• Requiem Audio Log 4 - Secret Lab: Only accessible after the lab has been opened during the main quest. The audio log is in the room behind players after they vault over the rail. It is on a table to the left of the canister device.

• Requiem Audio Log 4 - Room 305: In Room 305 of the Hotel, which is accessed using a Brain Rotted Zombie. It is on a dresser to the left of the bed.

• Requiem Artifact 1 - Klaus’ Hands: These are found on the bed in Room 305.

• Requiem Artifact 2 - CRBR-S: Picking up the Wonder Weapon from the safe at the end of the CRBR-S quest will also serve as a piece of intel.

• Requiem Artifact 3 - Rico’s Keycard: Picked up on the train during the main quest.

• Requiem Artifact 4 - Warhead: Picked up on the train during the main quest.

• Requiem Artifact 5 - Hacking Helm: Acquired during the main quest. Players will get the intel once they attach the helmet to Klaus.

• Requiem Artifact 6 - Improvised Collider: Built during the main easter egg’s Uranium step.

As is usually the case, most intel for the Dark Aether category is collected through intel trials. This time around, the intel focuses on Projekt Endstation and Valentina’s relationship with Dr. Vogel.

• Dark Aether Audio Logs, Radios, and Documents: These are obtained from completing intel trials. 2-3 pieces can be acquired in every match.

• Dark Aether Artifact 1 - Electrical Fuse: Collected from killing a Tempest. This is required to turn on power.

• Dark Aether Artifact 2 - Tempest Essence: Acquired during the canister step of the main quest.

• Dark Aether Artifact 3 - Corrupted Uranium: Acquired from the HVT during the main quest.

Call of Duty: Black Ops Cold War’s Season 4 Reloaded update also adds new intel to the Outbreak mode. The locations are as follows.

• Requiem Transmissions: Only Requiem gets Outbreak transmissions in Season 4 Reloaded, and there are only two. The locations for this Zombies intel are as follows. In Ruka, the transmission box is found on the table in the main building of the Cargo Platform area. In Golova, it is on top of the larger Granary silo that gamers can zipline up to. In Sanatorium, it is on the top floor of the large yellow house, resting within an office. In Alpine, it is seen as soon as players enter the Bathhouse. Duga’s Radar Control area houses the last transmission in its Listening Post building. On the top floor, players can find the radio in a room with wooden walls. Lastly, Zoo houses a transmission box in the Office Park area. Players can find it in the back room of the brick building with a wall buy.

• Requiem and Omega Documents: These can be acquired from any region, and they can be dropped from Golden Chests and mini bosses. Players can get 2-3 every game, though only one drops per region.

• Zoo Audio Log 1 - Requiem: In the center of a white table in the Industrial Complex. It is in the building closest to the barricade.

• Zoo Audio Log 2 - Omega: If players go to the crafting table bunker closest to the Gas Station, they can find this under some bunk beds. The right room is on the left side of the bunker.

• Zoo Artifact 1 - Requiem: If players are facing the Zoo entrance, they should enter the door on the left side. They can find this ECM model on a shelf.

• Zoo Artifact 2 - Omega: If players enter the Wolf Exhibit from the Zoo Overlook, they can find the Krasny Soldat flamethrower in the right corner of the first room.

• Zoo Artifact 3 - Dark Aether: If players head to the Maintenance Facilities section, they can find an Elemental Pop poster on a wall. It is at the back of the large building.

• Sanatorium Audio Log - Omega: On the top floor of the blue cottage. It can be picked up off a desk.

• Sanatorium Artifact - Omega: If players head to the Upper Suites that house the Wunderfizz, they can find some Dark Aether photos next to a bed. It is in the first room on the right after players head up the stairs.

• Alpine Audio Log - Omega: A new audio log about the Omega Group can be found in Alpine’s large Medevac building. It is on a green table.

• Alpine Artifact - Requiem: A Ring of Fire canister can be found on the leftmost Base Cabin. The cabins are near Alpine’s lone fishing spot.

• Ruka Audio Log - Requiem: At the crashed train near Railway Hillside where a wall buy can be picked up. It is on top of the train itself.

• Ruka Artifact - Omega: In the second foot of the tower at the Obstacle Course, an Omega Flag can be found.

• Golova Audio Log - Requiem: At the Rural Houses, players can find this Audio Log in a brown bar to the left of a shack. It is on the counter.

• Golova Artifact - Dark Aether: In the Lower West Town, players can find this artifact in the light blue building to the right of the statue and across from the jail. It takes the form of an Elemental Pop can, and will be on some shelves to the right as soon as players walk into the room.
