Alien captive recorded log

Alien Captive Recordings are items added to Fallout 3 in the add-on Mothership Zeta.

Description
There are a total of 25 recordings. Although they are usually not physical objects, the recordings will appear as holotapes when spawned via console commands and are stored in the Notes section of the Pip-Boy. Collecting all of them will grant the Alien Archivist achievement.

You will need to collect all the recordings while playing through the DLC's storyline, upon completion of the DLC you are only able to access The Bridge and the Engineering Core. All other areas are inaccessible. You can go back up until the death ray so make sure you have all the ones up to that part. But #19 is only accessible until the space walk. So if you're planning on getting all of the recordings, make sure you get the ones in Cryo Lab and Research Lab, because after you complete the final mission, they are locked and you need a key that is impossible to get. Spawning them through console commands will not get you the achievement. Also unlocking the inaccessible doors does not work, if you do not pick up all 25 by searching you need to restart the DLC.

Walkthrough
Without backtracking, the order is roughly:

1. Holding Cells (6 total)

- The first three {14, 15, 22} are together to the east of your initial cell on the first level. Don't follow your new friend.

-The next three {3, 1, 12} are again found together in the room just north of the quest map marker.

Steamworks (devoid of recordings)

2. Engineering Core (4 total)

- The locations of the four recordings on this level {5, 6, 7, 8} correspond to the four individual stasis controls on the pods of the samurai, astronaut, medic, and cowboy.

3a. Waste Disposal (via Maintenance Level) (1 total)

- The recording {19} is in the southwest portion of the waste disposal map.

3b. Cryo Lab and Cryo Storage (6 total; 4 in the former, 2 in the latter)

- The first recording {4} inside the Cryo Labs is down a short flight of stairs to the right of the level entrance inside a room with other earth-based misc loot. The second recording {2} is inside the stasis room containing a ghoul and raider. The third and fourth recordings {11, 17} are inside the room with Elliott's squad. Make sure you get all four from the Cryo Lab before progressing to Cryo Storage. Teleporting back from storage locks doors behind you in the lab.

- The first recording inside Cryo Storage {25} is just to the left of the entrance. The second {16}, is in the southwest corner of the map, downstairs.

3c. Research Lab (via Cargo Hold) (2 total)

- Recordings {13, 21} located inside the Research Lab.

4. Weapons Lab (1 total)

- The only recording {24} in this location is inside the lab control room. Do not miss the fourth-largest group of 87 Alien Power Cells on a shelf inside this room.

5. Experimentation Lab (3 total)

- The first recording {20} is inside the room with the two large chairs. The second {10} is on the north wall of the observation room. The last is inside the room being observed, next to the Abominations on the operating tables.

6. Biological Research (1 total)

- The penultimate recording {18} is on the second floor of the room in the north west of the map. After you reunite with Sally and the others at the end of this level, do not miss the second-largest group of 109 Alien Power Cells on a shelf inside this room. It is not possible to return to this location after teleporting out.

Death Ray Hub and Death Ray Control (devoid of recordings)

7. Living Quarters (1 total)

- The last recording {23} is inside a small room at the opposite end of the hallway from the samurai.

Trivia
Log 25 probably references two episodes of The Twilight Zone - the famous "To Serve Man" (in which the alien text by that title turns out to be a cookbook) and the somewhat lesser known "People Are Alike All Over" (in which a human astronaut is captive at a Martian zoo).

Log 24 could be a reference to "Destroy all humans" in which the first life form you contact is a cow which are mistaken as a humans.
