Prime

Prime is found dead at Dot's Diner near the Jury Street Metro station in 2277. His eye, however, can be found in a trailer park southeast from the station, lying on a brick near a table. On his corpse, one can find the unique Xuanlong assault rifle.

Background
Two hackers were attempting to divide some loot spoils, and Jiggs never made it out of the Museum of Technology alive, or survived long enough to solve a riddle Prime posed for him.

Quests
Jiggs' Loot: Prime has left notes in certain terminals in the Museum of Technology in order to help his partner Jiggs find "his share of the loot."

Effects of player's actions
Prime's corpse will only appear after one answers the three terminals in the Museum of Technology correctly.

Appearances
Prime appears only in Fallout 3.

Behind the scenes
Prime's name is a hint to how to solve the quest Jiggs' Loot. The three numbers that unlock the treasure cache are all prime numbers.
