Will there be a Fallout DLC which will allow the character to continue the game after the battle at Hoover Dam? I sure hope so

No and there is no reason you simply can't put off beating the game until your done with the character.

Hey.... just look through. There's already 5,000,000 threads On this

Dunno why you created two threads about the same thing. Also, instead of creating another thread about this subject why don't you use the search function. There have been eleventy-billion of these threads already.

Mods, please lock both threads. Please. Save us all the aggravation of having to read MORE of them.

One thread is more than enough for this discussion. They have already told us there will be no DLC to remove the ending of this game. Sorry.
