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 ammoe 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.

Gustavo will tell you to go in through the Warrington 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 wether 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 neighbours. 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.

Once all required tenants are convinced, visit Allistair Tenpenny for a 500 cap reward. Once you brings 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".

Help the ghouls break into the tower
You can let the ghouls in through the underground door. Gustavo has the keys to the terminal that opens the door underground. 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 wont attack you. You just need to get inside and watch how the ghouls massacre the tower residents. After they wipe out all the 3 floors, the tower will become a ghoul haven. Roy will also tell you that you can live here in your private suite. You can only get into your suite by going through Tenpenny's metal door, and turn left once you get outside. And will also give you the possiblility to loot the whole tower of items without gaining bad karma for stealing.
