I got too occupied in exploring the other areas then the beta ended. I saw a YouTube video where these 2 guys went back there there was a whole huge area there...if I can only go back I could have explored a bit more...
Edit 1) found a video in the end of the video he's in there

Yep yep, found it in the Alpha and revisited it in the Beta. It was cool and looked amazing, but there was nothing extraordinary there. Just a bunch of invisible walls.
