Nucleus Command Center

 is a location in the Commonwealth in Fallout 4.

Layout
Upon entering the command center from The Nucleus, you will be in a hallway with red alert lights & alarms flashing. The hall ahead will have numerous laser tripwires that move vertically along the wall. There is a room to the right of the entrance, which leads to a utility tunnel and - ultimately - a dead-end room with some junk loot and a weapons bench.

After the first hall with the lasers, you'll enter a rocky tunnel with a turret on the wall at the bend. As the tunnel turns left, watch out for another turret on the wall ahead as well as possibly a Mr. Gutsy. This area also contains some barracks rooms to the left and a facilities announcement terminal.

Another rocky tunnel leads you beyond the barracks into a kitchen area containing at least one Protectron on patrol. Proceeding past the kitchen/cafeteria area and up the stairs will take you through a longer tunnel, the end of which contains multiple leveled robots & two wall-mounted turrets. At that point, you'll find a security gate with a terminal on one side and a door on the other side leading back to The Nucleus. The room also has a trunk in the corner.

Opening the security gate will grant access to the terminal needed for Best Left Forgotten. Before you can use the terminal, you must enter the fenced-in area and activate the circuit breaker on the back wall. Doing so will sound an alarm and release a hostile Assaultron from behind the metal door.
