Fallout – Dead Money DLC and main story

fallout-new-vegas

I just bought Dead Money DLC, during Steam sales, but I haven't finished Fallout: New Vegas yet; I played about 25 hours and probably I am just in the middle of the story.

What does it mean? Is Dead Money DLC playable only after Fallout: New Vegas end or could/should I access its content before?

Best Answer

You should be at least on level 20 and you can access it before the end of the main story. More details (and spoilers): http://fallout.wikia.com/wiki/Dead_Money

EDIT: Today's (July 6th 2011) update fixed the fact that one could not engage on DLC's quests after main story ending.

New feature: system save is automatically created prior to endgame sequence. After credits, user is prompted to load save game. This will allow single save players to play DLC without creating a new game.
