Following in His Footsteps

Following in His Footsteps is a main quest in Fallout 3. It is also an Achievement on the Xbox 360 and PC; and a Bronze Trophy on the PlayStation 3.

Detailed walkthrough
NOTE: Where it says optional, it means the player character can skip the parts before it, like going straight to Smith Casey's garage will finish the quest and the player character will not have to go to Rivet City.

Megaton and '300 Pieces of Silver'
Objective: Investigate the nearby town of Megaton for information about James.

In Megaton, everyone will point the player character to the saloon owner, Colin Moriarty who will offer to tell you where your dad is if you give him 100 caps. If one does not accept the offer, he will ask for 300 the next time one talks to him. You can also use Speech to convince Moriarty that your father told you about him or choose certain dialogue options to get him to give the Lone Wanderer a discount, provided they agree to kill Silver and bring back the caps she stole.

The player character can find Silver northwest of Megaton at Springvale, inside a ranch house. There are seven ways of dealing with her:
 * 1) She can simply be killed and obtain 400 caps along with her equipment with no Karma change unless anything is stolen from around the shack. She will attack straight away if the player character says that they are there for the caps.
 * 2) With a successful speech attempt the player character can convince her to hand over 400 caps to tell Moriarty she is gone.
 * 3) She can be convinced to hand over 300 caps to tell Moriarty she is gone.
 * 4) The player character can ask for no money and tell him she is gone. This will result in positive Karma, though one will still have to come up with 100 or 300 caps.
 * 5) The player character can simply say she is gone without working out a deal with her, though again, one will still have to come up with the money on their own.
 * 6) With the speech check one can make her give hand over 400 caps. She can then be killed to loot another 100 caps from her body. The player character will lose Karma if they kill her after she gives them the 400 caps though.
 * 7) One can ask for no money and tell him she is gone. This will result in positive Karma. The player character can then kill her for 400 caps along with her equipment. If done this way, there will be no Karma change.

If the player character chooses the bad Karma path to interact with Moriarty, they can steal the password to his terminal out of a cabinet next to it or pass a Speech check with Gob, that will tell the Lone Wanderer about Moriarty's terminal. Asking him about the terminal after the Speech check will result in him telling the player character that Nova has the password. One can try to pass a Speech check or use Lady Killer (male character) to seduce her into providing the password. Or one can simply kill Gob and loot the password off his body. Obtaining the information will lead the player character to Galaxy News Radio.

Galaxy News Radio
Head to the Super-Duper Mart and from there across the Potomac to Farragut West Metro station. A room with mole rats has a stairway leading downwards. Then climb more stairs to find a chain gate with feral ghouls behind it. Beyond that will be yet another stairway and a door to Tenleytown/Friendship station. If the tunnels are followed south, they should exit in Chevy Chase.

One can also enter Tenleytown/Friendship station from Friendship Heights.

Near the exit to Chevy Chase North the PC will find Sentinel Sarah Lyons with a squad of Brotherhood of Steel soldiers from Lyons' Pride. If talked to, Sarah will allow the PC to accompany her squad to the GNR building plaza, clearing out the super mutants in the nearby Early Dawn Elementary School in the process. The PC may then aid the Pride in an assault on the super mutants, super mutant brutes, and super mutant masters attacking the Galaxy News Radio building. Once the other mutants are dead, a super mutant behemoth is unleashed from behind a destroyed bus, which the PC may help destroy. A Fat Man nuclear launcher off the dead body of the Brotherhood soldier in the central fountain (there is a map marker pointing to it) will heavily damage the behemoth.

Depending on how fast one takes the behemoth down and who dies in the process, the conversation with the remaining soldiers goes differently. Use the intercom to the right of the door to get inside the GNR Building. Once inside, talk to Three Dog. One has two options at this point. If the player character has a high enough speech, they can convince him that after they have rescued their father he will help the cause. Doing this will give the player character the Scientific Pursuits quest for free. However, if one has insufficient speech, he will give the player character the Galaxy News Radio quest, which they will have to complete first to in order to get Scientific Pursuits.

If the speech check was successful, talking to Three Dog again will result in him offering to exchange the location of a large cache of military munitions in return for the Galaxy News Radio quest. This allows the player character to explore the quest for greater returns.

The Search Continues
Killing Three Dog without getting him to tell the player character to go to Rivet City ends the GNR quest and starts a new quest called The Search Continues. The objective is still to find Dad, who can still be found at Vault 112 and the Lone Wanderer can still talk to Dr. Li. This does not result in the achievement however.

Skipping this quest
Note that this quest can be fast-tracked by skipping several steps:
 * Visit Three Dog without speaking to Moriarty.
 * Retrieve the Project Purity journals from the Jefferson Memorial.
 * Go directly to Doctor Li in Rivet City.
 * Travel to Vault 112 where James is imprisoned.

If one ends up finding Vault 112 before visiting Three Dog at GNR building plaza, this entire quest will be marked as completed. If the player character makes it to the building, they will still encounter all of the super mutants (including the behemoth) with no Brotherhood of Steel soldiers in sight. (This will also happen if Li is spoken to or one has retrieve the Journals first). The door to GNR will be locked but if unless the intercom is used after the mutants have all been killed, the Brotherhood of Steel soldiers stationed inside will let the player character in. One can then speak to Three Dog and get the achievement for Following in His Footsteps. Additionally, he will offer the Galaxy News Radio quest in exchange for the key and coordinates to Hamilton's Hideaway.

If one takes this quest as normal and chooses to find out about Dad on their own, e.g. from Doctor Li or from Vault 112, returning afterwards to place the satellite dish, Three Dog will remark on how the player character did not need to do as he asked. One will receive good Karma and the key to the weapons cache at Hamilton's Hideaway.

Bugs

 * There is an occasional glitch where the super mutant behemoth will not be triggered to appear. GNR will not open its doors, and the BoS soldiers will reach the fountain and then wander around the plaza aimlessly. If you speak to Sentinel Lyons, she will repeat her dialogue "You can tag along with us as far as GNR." A similar glitch occurs when, even after defeating the behemoth, the doors to GNR remain locked, even though the BoS soldiers enter it.
 * It is possible that, after entering GNR and leaving right away, the generic BoS paladins will become hostile and attack. If the player character kills any of them, the others (Lyons, Vargas, etc.,) will also attack and one will receive bad Karma.
 * If the player character does go directly to Vault 112, and finish " Tranquility Lane " quest they will not be rewarded the trophy for " Following in his Footsteps " or any quest that may follow this.
 * When battling one's way to the plaza, they will come across a small area with a pre-War playground. The first super mutant in this area may appear as non-hostile in V.A.T.S. and when pointed at, but the BoS soldiers will still shoot it down.
