LOCKDOWN

Your base has an emergency lockdown protocol. At the press of a switch, heavy doors slam shut throughout the base, sealing it off from the outside world. Nothing, not even bacteria, can escape from a locked-down base.

Effect

If lockdown is activated, nothing can escape the base using conventional means. Lockdown also means that the base has its own internal air supply, which can come in handy if the whole building is abducted by Judoon.
