-If you are updating from V6.1 or older, remove any items you have placed on the mannequins before updating or you will loose those items. Otherwise, dont worry about it.
-You must Exit the armory area and save before installing to the new version.


The entrance is located West of the “Rivet City” Entrance in the Parking lot with the crashed planes and wrecked cars.


Regular Version -Fallout 3

DLC Version - Fallout 3, Anchorage, The Pitt, Broken Steel, Point Lookout, and Mothership Zeta. All of the DLC must be int he Fallout 3 data folder. You can not use LIVE to load the content. You can use Disable Live to move the content. If you do not do this and still use the DLC version, Fallout 3 will crash on startup.

-I recommend using FO3 Patch 1.7 since this is the patch version I have used in creating it.

-You must use ArchiveInvalidation Invalidated (or FOMM equivalent) to avoid any problems with textures.

-Fallout Script Extender is required to use the Weapons and Armor Sorter


To install,unzip the folder and copy the contents to the fallout 3 data folder. To uninstall, uncheck and Delete the Plug in File named "Underground Hideout.esp" and the "UndergrounfHideout.bsa" from the C:\Program Files\Bethesda Softworks\Fallout 3\Data folder.

I made this home for personal use and felt others may enjoy it too. I had a blast figuring out the GECK and think it turned out well for my first mod.
