You can get away with skipping around 10 missing persons and still manage to unlock the Missing Persons achievement, but a true completionist should seek out all of them. Be advised that using recycler grenades can be severely damaging when it comes this achievement, because recycled bodies will display as an empty, crossed-out name in the crew roster (meaning they’re unable to be found, identified, and cataloged).

That said, here’s a list of missing volunteers and persons that should make scavenging through Prey an easy task.

Missing Volunteers in Prey

There are 18 volunteers that you can find in Prey. Volunteers are different than regular missing persons or crew members, because they can only be found in the Volunteer Quarters of the Neuromod Division. The list below is in alphabetical order and gives the exact location of each volunteer.

 

Missing Persons in Prey

Finding all 268 missing persons in Prey unlocks an achievement. All throughout Prey, you’ll find deceased crew members and other personnel scattered throughout the Talos 1 Space Station. You need to find the corpses of all these unfortunate people in order to complete this achievement. There are a few of these missing persons that are still alive, too.

On the Security Station terminals, you can check the Crew tab to view which missing persons you’ve already found. You’re also able to track each individual person’s location. Below is a full list of every missing person in the game, sorted by the location that they can be found.

Neuromod Division Missing Persons

 

Talos 1 Lobby Missing Persons

There are several missing persons in this area that are actually still alive, and will be noted as such in the table below.

To find Harley Grainger, Maxine Ford, Richard Coveney, and Steve Folson, initiate the Showing Initiative objective by becoming a psychopath before Dahl arrives in Life Support.

 

Hardware Labs Missing Persons

 

Talos 1 Exterior Missing Persons

Jessica Wiley, Riley Butler, and Tana Vale can only be found in the Cargo Bay after the explosion. To move to the Cargo Bay, bring Dayo Igwe there by completing the Dr. Igwe objective. After completing this objective, you may bring him to Talos 1 Lobby, Neuromod Division, and Shuttle Bay.

Aboretum Missing Persons

Although I’ve yet to find out which particular action triggers it, Alex Yu may otherwise be found on Talos 1 Bridge near the end of the game. Rani Chaudhary can also potentially be found in Cargo Bay or Life Support, depending on your actions after saving her from the Telepath in the Greenhouse.
