Trouble on the Homefront

 is a Fallout 3 quest. It is also an Xbox 360 and PC achievement and a Playstation 3 trophy.

Objectives and walkthrough
This quest will be activated anytime after completing The Waters of Life quest (which is part of the main storyline) by picking up the Vault 101 Distress Signal on your radio. To pick up the Vault 101 Distress Signal simply wander near Vault 101 (Megaton is close enough). It is a message from Amata asking you to return to Vault 101 to help stop her father, the Overseer. If you killed the original Overseer while escaping from Vault 101, Allen Mack will be the new Overseer and you can still do this quest.

Since you and your father's escape from Vault 101, the Vault has been fractured into two major factions. The faction led by Amata, holed up in your father's Clinic, wants to open the Vault and interact with the outside world. The other faction is led by the Overseer and he wants to keep the vault closed permanently, in accordance with its mission.

Solutions
You have a few options to finish this quest:

 Kill the Overseer.


 * Note: ''Interestingly enough, if you kill the Overseer but don't gloat, Amata's speech to the PC regarding the "tough decision" of asking them to leave the vault is strikingly similar to the speech given to the Vault Dweller of Fallout 1 at the end of that game. See quote below.



Kill Amata if she becomes hostile.

Kill all of the rebels. (not viable if Amata's father is Overseer)

Leave without doing anything (this decision, if you make it, is permanent).

Persuade the Overseer to open the vault with your Speech skill (Only available when the overseer is still Amatas father).(Note: I shot the Overseer in the leg but did not kill him during the escape, and thus he was automatically hostile towards me when I returned.)

Persuade Amata to stay in the vault with your Speech skill.

Go to the jail and use the computer there to find out about Security's plans to raid and kill the rebels. The computer is locked; you can hack it with sufficient science skill, or you might be able to find the password simply by searching the lockers in the room, or else you can find it on the hostile Officer Wilkins. Then, talk to the Overseer and tell him about Security's plans. This will have the same effect as if you persuaded him with your speech skill. This only works on Amata's Father, not if Mack is the overseer.

Hack the computer in the sub-basement (75% Science) or steal the Pass Card from Stanley, the maintenance man, who can be found wandering around the cafeteria/dorm level. Go into manual override mode and perform a flush and a purge. This will flush the water chip. Lie to Amata that it was the Overseer's plan. Everyone is forced to evacuate the vault and you will see them spread out in the Wasteland (you lose Karma for this). If you complete part of the quest (kill Amata/Overseer or peace either way) you can still flush the water chip. It doesn't work if Amata's dad is not the Overseer.</li>

Hack the Overseer's computer and discover the attempts by the Enclave to gain entry into Vault 101, and the Overseer's refusal to admit them. Speak to Amata and tell her this and it will convince her to stay in the vault.</li>

Bugs

 * It has been reported that Butch could appear in the Muddy Rudder in Rivet City even if this quest is resolved in such a way that would preclude his appearance in Rivet City. (This includes convincing the rebels to stay, or even killing the rebels)
 * On the PS3 version many people have experienced the game completely shutdown whilst exploring the vault and exited to the menu. It's a constant bug during that whole section of the world map.
 * On the PS3 version I have encountered a different bug, I was fooling around and kept going back to a previous save game, when I went to go again I was unable to pickup the frequency, disabling me from getting the password for the vault door which is Amata. This is before patching to 1.10.
 * When you get done talking to Amata she followed me outside the vault. When the door closed she ran against it trying to get in.
 * I spoke with the overseer and convinced him to step down and make Amata the new overseer. He ran down the hall to talk to her, I followed him.  Right after he went through the door, he stopped at the head of the stairs and started speaking to Amata, even though he was nowhere near the clinic yet.  He stood there and recited his entire speech.  I then went to the clinic and spoke to Amata.  After she told me I had to leave the Vault, the overseer ran into the clinic and repeated his speech to her.
