Killing Floor 3 has great missions, but sometimes it is not clear how to complete some of them. I’ve had some confusion with a certain mission named Absolute Massacre where you need to collect tainted corpse samples in the Army Depot Stage.
These samples in Killing Floor 3 are acquired through dead bodies you find around the map. In total there are three tainted corpse samples you need to collect to complete the Absolute Massacre mission.
How to Complete Absolute Massacre Mission in Killing Floor 3
The entire mission is set on the Army Depot stage in Killing Floor 3. This is where you will find three tainted corpse samples to complete the mission. The samples are inside the Inspection Room and the room inside the base. The room has a shuttle in the middle of a big room.
Tainted Corpse Sample Location #1

When you’re inside the Inspection Room, go up the second floor near the shuttle to find a dead body. Loot the body to get the first tainted corpse sample in Killing Floor 3.
Approach the body and Press E if you’re on PC to loot the body and do it before the wave starts. You can do it in the middle of a wave too, but it’s not an ideal situation for sure.
Tip: All lootable bodies we are looking for have a golden light emitting from them, making them easier to spot around the stage.
Tainted Corpse Sample Location #2

You can drop down from the second floor using the platforms on the side. One of these platforms have the second tainted corpse sample.
Tainted Corpse Sample Location #3

The next and final tainted corpse sample in Killing Floor 3 in one of the corners of the Inspection Room. If you’re having trouble finding any of the samples, refer to the images under each location I’ve shared.
Once you collect all three of the samples the mission, Absolute Massacre will end. You shouldn’t have trouble finding all locations because the game does offer general direction to the corpses and since they are all in the same room, all you have to do is run around to spot the golden marker.
