Nodding he walks in. The first door shuts and the checkpoint opens. "State your business and number of cookies. " A unseen voice says. "SHADE4XM8" He says to the nothing. "Granted. " The door in front of him opens, but he doesn't enter. "Someone new?" THe voice says. He nods. The door infront of him closes and another one opens. Opening the radio channel while walking down the hallway, he tells them."Ok so don't go through the main door. Go about 10 feet from the door and knock 3 times, pause, then knock again, and it should open. Go inside and I'll meet you there. If you have anything to ask, do it now because there is no radio, service, anything after we get inside. It's locked down hard."
