so....
like the topic says... can i play HH after finishing the game or do i have to go to back to one of my savegame files?

Well once youve finished the game its done. In order to play you gotta load.

No, you can't play after the game ends, no NV DLC will be playable after game is over.

If you mean if it extends the main game.......No and that will never happen.

If your asking if you can go back to zion after the main quest there then........... Yes just no quests

what do you mean no quests? like you cant do any side quests after you finish the main one?

yes you are able to go directly back after youu beat the DLC honest hearts. thank you for listening to us obsidian! :fallout: oh, and if you dont know how to go bck to the national park , the entrance to it is in the cavern, its there. you can come back to it whenever you please.

above im talking about when you beat the DLC, thats what i thought you asked, sorry

There are no side quests... only the main one.

nooooooooooo,

There are some FO-3 style bonus locations though with a story behind them, it's actually really well written and can be done at any time.
