So when bungie opened the moon for a few hours during the beta they also open that door. They didn't announced it like they did with moon but it was only for a few hours anyway and everybody went to the moon. But I for some reason or another I didn't I stayed at the tower and explored some more, went to go see the speaker one last time before the beta ended and what do you know the door was OPEN!!! I couldn't of believe it. When I went in it was like an open area, merchant bizarre type area I guess. It almost seem to go on forever running down the open corridor past the useless npc's. But I had to stop so I could get some moon time in real quick as the beta was coming to end. Good luck getting back in there if bungie dosnt let you in first. I wonder if I was the only to see and get in. Any other alpha or beta players get in or see inside?
