If you have the GOTY edition, use the bonus disc to install the downloadable content. Then next time you actually start the game you should have the option to play the other content. They should latch on automatically.
This is for only xbox360, I'm not sure how it works for other systems.
A pop-up will appear saying the DLC has been downloaded raising the level cap to 30. After that if you beat the game it will continue
No, if you want to continue your adventure, you need to buy the add-on ''broken steel''.
The 'reward' for beating it on Hardcore mode is an achievement/trophy, nothing more.
Unfortunately, nope; just get the DLC.
It depends. After Fallout New Vegas's recent release and the announcement of Elder Scrolls 5, a Fallout 4 could be predicted to be released in 2012, at least. If that sells well, and Bethesda decides to continue the successful series, than there likely will be a Fallout 5.
No obsidion said they would not release dlc that extends gameplay past the ending
no you continue with what you already had
None of the Fallout: New Vegas expansions allow you to continue after you beat the game.
Nothing, you can just continue playinh the game indefinetly.
just continue on with the main quest and you'll be able to do it.
Yes, you do. You continue your fight for survival though out the Capital Wasteland.
If you mean after you have finished the main quest line then no you have to load a previous save.
