So, first time playing through, but I see this and wonder why they don't just leave?
Those glass doors aren't keeping me inside. I don't care what kind of glass they are, I'm getting through it within an hour, even if it's multi-layered laminated glass, I'll find something hard and heavy and smash it out bit by bit if I have to.
Do none of the rooms have windows to look out of? Are all the interior walls made of concrete?
Because if it's like a normal building I'll be taking out windows, doors, plaster-board walls .etc.
Also tall buildings have fire escapes/stairs because when there is a fire or other emergency often the elevator doesn't work.
Are we supposed to believe that the door access to the stairs is impenetrable?
But yeah, main point, I see glass doors facing directly outside, no one is keeping me in.
