On this page of our guide to Wolfenstein: Youngblood you will find a detailed description of Missing Resistance Fighters side mission. This task concerns finding the missing members of the resistance. Unfortunately, they will be dead by now, but you will find 4 decodable floppy disks.
Who's commissioning the mission: Talk to Dimitri Fedorov at the catacombs.
This task takes place in Brother 3 district where you could have unlocked a fast travel point (subway) - see separate pages of our guide for more information. When you reach this district, set the mission as active and follow the instructions on the mini-map.
In order to complete the first part of the mission, you must reach 4 dead members of the Resistance. The remains will be in different parts of The Brother 3 base.
The first body is in the same closed room where you found the Elektrokraftwerk weapon in the main mission raid. Once again you need to go through the ventilation shaft.
Interact with the corpse to move it and find the Information Cache Code #2 disk. Use the Elektrokraftwerk (shoot in a fuse box above the door) to get out of the room.
The second body is on the floor. You must use a double jump to reach the ceiling area shown in the picture. Get to the body and take a new disk (Information Cache Code #3).
The third body is in the lobby, which means you need to use the elevator to get there. You will find the corpse in the cinema room (watch out for surrounding enemies!) and there you may find a floppy disk (Information Cache Code #1).
The fourth body is in the archive, where you fought against Boss Bruder 3 in the main raid mission. On your way to the archives, you should reach the elevator and use it. Before you enter the archive again, the sisters must also pull the two levers shown in the picture.
The body is covered by the load of a forklift truck. Use the Elektrokraftwerk weapon to shoot at the wheelchair motor. The charge will rise and expose the body with a floppy disk (Information Cache Code #4).
The next step is to decode all disks. You can simply reach the terminal indicated by the game. Each disk will contain one combination digit. Full code is 1609.
Reach the keyboard at the entrance to the secret room and enter 1609. Secret Documents lie on the table. Return with them to Dimitri in the catacombs and complete your mission.
