After looking around I never found a clear answer on, if there was free roaming after the main mission is complete that is the line that decides my decision.

I suppose you aren't going to get the DLC then, this feature isn't in Dead Money and they have said that they won't make one that does it.

You can just revert to an older save, though. Unless you only use one slot and disregarded that message that told you it was the end, then... well. I have no sympathy.

No, there is no DLC like that and they have expressed that they are not planning to do one either.
If on PC then use mods, if on console then reload prior to the final quest.

Nein.

No, they confirmed that this feature will not be in any Fallout New Vegas DLC.

When did they confirm it? Link please? I hope its not true, dead money didnt come out very strong for me, and I was hoping for some point lookout style dlc that would actualy be good.I dont realy want 3 more deadmoney/o.a., where I walk around tight pathways and shoot stuff, and then never go back. :cryvaultboy:

I see somthing about not making any broken steels, that I dont mind, but I didnt see any thing about them not making DLC that you can return to/explore.Did I misread what this thread is about, or did I just not see it in the link?

well hopefully they'll bring out a dlc that you can return too, consider they had the mothership unreturnable. so maybe they go in a pattern
