Gate A is the main entrance to the facility, it can be used as an escape route for survivors if going through Gate B proves too difficult. Gate A has a bridge with site lines at the elevator and at the main street gate. Gate A also has two ways of reaching the street either from the elevator or the bridge. Gate A also has the Warhead Control Room, which is where the Alpha Warhead can begin it's detonation sequence, once it start it can't be stopped via through Gate A and can only be enabled and disabled in the Alpha Warhead Silo, it's also where you can cancel the detonation.
SCP: Breached Containment has a special room designated for the Omega Warhead, a 5 megaton warhead, capable of vaporizing anything in a five mile radius, this also bypasses the Blas shield between the surface and the facility. This can not be detonated by normal means and can not be cancelled. During it's preparation for detonation, the Alpha Warhead is completely locked, even if it's counting down.
