My Megaton house

The Megaton Shack becomes available after you complete the The Power of the Atom quest. The Megaton Shack is located in Megaton.

This shack can be yours if you decide to disarm the bomb that is located in the center of Megaton. Besides being a resident and proud owner of your new home, you can improve it too. For example, you can outfit your house with an infirmary, jukebox, laboratory, nuka-cola machine, and workbench. You can also change the scenery from a run down shack to: Raider, Wasteland Explorer, Vault, Science, Pre-War, and Love Machine (try to find the song "Love Shack" on the jukebox if you have the love machine scenery.)

Also, you get a robot butler, Wadsworth who is able to tell you jokes, supply you with Purified Water, cut your hair and explain what your 'improvements' are used for.
