Locked? Yes, you have to help defend the plaza from the super mutants, then speak into the intercom to gain access.
I'm probably gonna post this as another thread, but I was wondering if someone could help me.
I'm just at the end of the Galaxy News Radio quest, standing in Chevy Chase, and the only thing left to do is to talk to Mad Dog. I can't open the door to GNR, it says it's locked I need a key. I try the intercom, but the guy just says "The door's unlocked, quit buzzing me" (which so does not help hahaha).
So, basically what I'm asking is HELP. This has been driving me nuts for months, and I thought it was something that needed to be updated through LIVE, but apparently that's not the case.
