Replicated Man holotapes

The  are a series of holotapes in Fallout 3. They are directly related to the quest "The Replicated Man" and can be found all over the Capital Wasteland.

Locations
Although the locations are fixed, you will not always find the same tape in the same location. Instead a tiered system is used to determine which actual holotape you receive; once you have uncovered a clue of a certain tier, you will advance to the next tier when finding another. For example, if you have already found a tier 2 clue, you will find no other tier 2 clues anymore - instead you will find a tier 3 one. In addition, there a different versions of the tier 1 and tier 3 clues, depending on the type of person you received them from.

The remaining two tapes are received in more conventional manners. Doctor Zimmer gives you Self-determination is not a malfunction at the beginning of the quest and Horace Pinkerton supplies Pre-Harkness Audio Recording at the end of it.

Clue providers
You can receive clues/tapes from the people listed below. The word in the top table row is the "type" which determines what tier 1 and tier 3 clue you get from that person. Generally, you always have two options to obtain each clue: either through dialogue or through a terminal/tape in the NPC's possession.
