About:

Understone is a settlement located within a cave where people take refuge from the world above.  This mod takes the Understone ENHANCED mod and makes a few changes and fixes to the mod.  Note: This mod is meant to be used with DUST Survival Simulator.

Changes:

1.4
-New Update??  Yes but it's merely a small one, the repair bot was removed and now Old Ronnie can repair your gear.  The reason I changed this is because you can't edit the repair skill for protectrons, meaning their repair skill will only be 0 and you wouldn't be able to repair your gear, now that's changed.

1.3
-General optimizations to the interior cell. (NPCs shouldn't spawn in one spot now)
-Added two dogs, one outside and one inside.
-Changed some of the understone guards to not all wear the same armor and have the same weapons.
-Added another two guards outside with one running a larger patrol around the area.
-Added a mini quest to add a purifier to the settlement so that you can purify dirty water.
-Expanded the clinic area.

1.2
-Added an alternate start option when starting up a new character, just turn around and read the note on the box (NOTE: This alternate start option can be considered a bit OP as it's much easier to start here).
-Honestly, there were some other things I've added in there but I've completely forgotten about them, so expect there to be new NPCs that are possibly unfinished.

1.1
- Reworked Calvin's cigarette to ammo dialogue.  You can now trade cartons in and the ammo you get is a random value, based on how many packs/cartons you give him.
- Added Alex, who will give you caps for scrap electronics.
- Added a outside guard to protect the outer door of Understone.
- Fixed certain dialogue options.

1.0
- Small optimizations to Understone's interior cell.
- Removes the .esm dependencies on the Caravan, Classic, Mercenary, and Tribal packs.
- Fixes Calvin's dialogue where you were able to obtain unlimited ammo through certain dialogue options.
- Adds a few more unique NPCs that you can interact with through dialogue.
