After a few minutes descending the stairs, the group of a few dozen people reached an open area, it was the highest floor on the facilities building just below the elevator, and Mack could see a few plaques giving directions and several smaller elevators just like any elevator from Earth. But each elevator went to specific floors instead of going to all of them, Mack guess they projected this way for security reasons again, because this way everyone would need to come to the lobby area, where Mack was now, to get other elevator if they wanted to go to other floor of the facilities building, creating a virtual checkpoint where guards could arrest someone.
And just as Mack thought of that, he saw several guards arresting a guy.
"I surrender!" screamed the guy, realizing he had no way to escape.
