Tenpenny Tower (quest)

Tenpenny Tower is a Fallout 3 quest connected with the Tenpenny Tower location. It is also an Xbox 360 and PC achievement.

Walkthrough
The ghouls want to live in the luxurious Tenpenny Tower, but neither Allistair Tenpenny nor other residents are willing to let them in.

Kill Roy Phillips
Given by Chief Gustavo at the Tenpenny Tower, you get a 500 cap reward upon completion and Assault Rifle with no spare ammo before you start it, in order to kill ghoul leader Roy Phillips. With speech you can get 700 cap reward and Chinese Assault Rifle as starter gun. (Note) He also gives you a few rounds for just accepting the quest, that is if you pass the speech check.

Gustavo will tell you to go in through the Warrington Train Yard which is west of the Tenpenny Tower. But if you go to the southwest about half a grid square you will find the entrance to the Warrington Station, you can actually see it as you exit the Tenpenny Tower. Follow the tunnels and you'll find a door leading to Roy's hideout. After talking to him, you'll get the option of whether to kill Roy, or to help Roy open the basement door to let the ghouls into the Tenpenny Tower. Alternatively, you can try to convince Allistair Tenpenny to let ghouls move in.

Convince Tenpenny to let the ghouls move in
Allistair Tenpenny, who is on the top floor of the Tenpenny Tower outside on the balcony, will tell you if convince tenants Mr. & Mrs. Wellington, Mr. Ling, Ms. Montenegro and Ms. Lancaster to have the ghouls as neighbors. With the help of charisma boosters i.e. alcohol that I've found throughout Tenpenny Tower you can get all the tenants to agreed to live with the ghouls. If you fail to convince someone, killing them will also work, so long as the guards don't catch you. You can also threaten some of them into leaving the Tower.

Once all required tenants are convinced, visit Alistair Tenpenny for a 500 cap reward. Once you bring Roy Phillips the news that the ghouls can move into Tenpenny Tower he will reward you with a Ghoul Mask that makes you friendly with all ghouls. You will also gain a 360 XP reward.

If you return to Tenpenny Tower later on in the game you will notice that all the occupants are now ghouls as well. When you question the main ghouls about this you will find out that they effectively killed all the human tenants because they had a "misunderstanding". They also tell the player to ignore the smell coming from the basement...I wonder why?

BUG NOTE: There is a bug with this quest in which if you talk to the residents to convince them to allow the ghouls to move in. You need to talk to Tenpenny about it first, before talking to the other residents, otherwise you can not complete this part of the quest.

BUG NOTE2: If you loot Ms. Montenegro's (or Ling) safe she will leave the building and you will not be able to solve the quest without killing.

Help the ghouls break into the tower
You will receive bad karma for this act.

You can let the ghouls in through the underground door. Gustavo has a key to the terminal that opens the door underground and also Herbert "Daring" Dashwood has a copy of the key. If you find him and persist that he gives you the key he will turn it over, allowing you to avoid shooting Gustavo for his key. The terminal is located in the generator room which can be accessed via a stairwell behind the Tenpenny Tower (Check Pip-Boy Local Map while standing in tower courtyard for location). After you let them in, Roy will be waiting outside at the entrance and will give you a Ghoul mask, so that the invading frenzied ghouls won't attack you. You just need to get inside and watch how the ghouls massacre the tower residents. You can either accompany Roy through each floor and watch the massacre and/or participate, or leave for a few hours while the bloodbath ensues. Upon returning speak with Roy and he will tell you that you can live in the towers private suite. The suite is located on the third floor (which can be reached by using the elevator on the ground floor and taking a right after exiting the elevator.) Also, you can trade and get repairs from the new ghoul NPC's that occupy the lobby.

Note: While the chaos ensues, the player is free to loot the corpses of the former tenants and ransack their stores and belongings, free of any negative karma.

Kill Gustavo and Roy Phillips and loot the lot
If you are interested in finishing this quest, just be carefull you do not kill both Roy Phillips and Gustavo. You will still have 2 markers on your map, but remain unable to finish the quest.

New Solution
After you convince everyone to let the ghouls move in, go immediately to Tenpenny. Complete the quest and collect the 500 caps.

Next, go see Roy at his hideout. Tell him he can move in to the tower now. After he moves in, find a quiet place where he is alone and murder him.

Now, all the ghouls and humans will live together in the tower and no one else will die.
