What the phuck?! Batman mentions the Batcave during the side missions, but I didn't know it existed in the game. But where and how do I get there? Or is the Batcave DLC just an add-on and something entirely new?

Since I don't have this anymore I don't know anything about the DLC and what it includes. I don't remember anything about the Batcave in the game.

Can't remember the exact dialog, but Bats was talking to Oracle with regards to Hush (the dude that looks like Bruce Wayne) and doesn't have the necessary tools to further analyze it and that he will save it for when he returns to the Batcave or something to that effect. So, naturally, I got excited that there would be a Batcave scene in the game. Sadly, it never came.

I haven't played this game much in the last couple of months, which means I haven't even bothered with all the DLC for the game either. I will definitely pick up this edition once the price comes down and I will probably sell my Collector's Edition of the game on eBay with the statue and all the other bonus stuff that came with it.
