Jiggs' Loot

 is an unmarked Fallout 3 quest.

It starts when you activate a terminal on the ground floor of the Museum of Technology and receive a note called Tech Museum Loot.

Treasure Hunt
There is a secret series of codes hidden within access terminals around the museum, as part of a series of security tests for a scavenger, Prime's allocation of loot for another comrade expected to show up at the Museum. The first terminal is on the wall straight ahead when you enter the museum. As soon as you enter the west wing, the second terminal will be on your immediate left (it will be the second terminal to the right). The third terminal is on the bottom floor near the Delta IX Rocket. The safe is located west of the planetarium in the security office that overlooks the Virgo II. The terminal codes are:


 * Terminal #001 - 19 (Ground floor, across the entrance room) (The same terminal needed to start the quest)
 * Terminal #002 - 53 (In the Museum West Wing, which is past the Vault tour)
 * Terminal #003 - 113 (Ground floor by the Delta rocket)

Note that when you first click on #001, #002, or #003 the correct answer will be highlighted on the next screen. But if you back out without selecting an answer and then click again on #001, #002, or #003 the top answer will be highlighted. After installing the patch, the top answer is always the defalt answer.

Although Prime alludes that he has left '...the usual breadcrumbs' for the player to follow, the clue is actually in Prime's name, as the correct numbers are all prime values (divisible by only themselves and the number 1, for example, 2, 3, 5, 7, etc). Successfully unlocking all three terminals will grant the player the password for the Security Office terminal, allowing them to unlock the safe. You only get one shot at this so if you make an error, you will not be able to complete this quest and therefore be unable to obtain the Xuanlong Assault Rifle.

Inside, the safe holds a few hundred caps (200 approx.), sundry other valuables, and a Gun Closet Key for the planetarium office's cabinet. This cabinet contains several firearms, including a Laser Pistol or Missile Launcher and assorted ammo (greatly varies, usually 3x assault rifles and a random weapon/ammo). There is a Nuka-Cola Quantum in the office as well.

The player also receives another note from Prime, Earned Your Share, in which he tells his buddy to meet him at the "usual spot", the Diner near Jury Street Metro Station, which is marked on your map the moment you access the password. By the time you arrive, Prime is dead, torn apart (lying on a table behind the counter), but is still worth finding, as he is in possession of 500 more caps, explosives, ammo, and a unique weapon, the Xuanlong Assault Rifle. A couple of Raiders might be at the location, and a Super Mutant Behemoth spawns west of there.

Rewards

 * Xuanlong Assault Rifle
 * 500 caps
 * various guns and explosives

Bugs

 * You can bypass all the hacking and lockpicking by hiding in the Planetarium and waiting for the 2 Super Mutants to start arguing in the middle. Once you attack them (keep trying to hide), they'll both run for the utility room to get the missile launcher even though they're not supposed to know about it and the locker is locked. Just make sure you snipe the one with the missile launcher before he hits you once they come out of there.
 * Sometimes unlocking the third terminal doesn't give you the password for the security office. Even after hacking the security computer you cannot unlock the safe. You can try unlocking the terminals in different orders though, this allegedly helps in some cases (edit - after you get all 3, you have to return to the first terminal to get the password[Note on the edit- after activating all three terminals any of the terminals can give you the code, you just have to ask.])
 * After activating all the terminals and getting the note, Prime's body did not show up at Jury Street Metro. Found a hand belonging to him outside, but no loot.
