At first, sorry for my bad English....

Completed main story, but still something different....

How? In this save:

1. Hoover Dam - it never happened. Hoover Dam is intact and is open for exploration. :)
2. Hidden Valley - BOS still there! :D Allayed with NCR, also intact and is open for exploration (no smoke). :)
3. Lucky 38 - Yours and open for exploration with all robots in there. Mr House disabled, and you can see him in his chamber.
4. Enclave bunker unlocked, and player have power armors
AND MORE! Save where everything is ok and is open for exploration.

P.S. Some side quests not completed so have fun with finding them. :D

I am using Freeside Studio Apartment by AlephDervish (http://newvegas.nexusmods.com/mods/39150/?) as savehouse, you can find all my picked up weapons and armors in there. Enjoy.

For your own taste, use console commands to change character face, stats, skills and other things...
