Ok so i am working on the security but there are few things i added.
Hopefully you like the ideas 

A secure door that can be locked and unlocked by both teams. The button that locks the door is on the last lobby floor next to the door as you can see. And the unlock one is on the first floor. The realy bottom.

Alarm button the roof. Allies can press the button to inform everybody. I am still thinking if it would give some advantage. Oh the light is hard to see on top so i am gonna add light everywhere around the Empire State Building. Inside on some lights and so on.
But i cant get those mother*ucking Security Cameras working can someone help me with those
