Forbidden Zone Dome Entrance

Forbidden Zone, known as the X-42 robo-warfare facility before the exile of Mobius, is a location in the north-east of the Big MT. It was originally named the X-42 robo-warfare facility but was changed by Dr. Mobius after he left the Think Tank. While the dome itself is accessible at any point, entrance to the X-42 robo-warfare facility can not be gained until talking to Dr. Klein during step 1 of the quest Old World Blues.

Layout
One big room with the X-42 giant robo-scorpion in the center, there are various stairs leading up to the edges or the room with many observation rooms, where about half of the rooms have computer terminals with information on the testing and creation of the X-42 giant robo-scorpion. The player may use these terminals to damage or disable the X-42 giant robo-scorpion. Some cause damage to the unit, and one (located on the far upper left as you enter the room) allows you to disable it by turning it friendly to you. This option, however, makes it un-lootable but it is still possible to kill the X-42 giant robo-scorpion when it is shut down, allowing you to then loot the remains.

Notable loot

 * 4 proton throwing axes in the room in the southwest corner
 * Audio Sample - Mobius' Robo-Scorpion, located on the center desk right in front of the north exit on the second floor
 * The Emergency Shutdown Terminal Password can be found by the protectron containers, Northeast corner of the ground floor, near the last container.
 * A Duffle bag can be found behind a skeleton, in the Northeast corner of the room. It contains 3 Boxing Times, and various other random loot.
 * A large amount of Mentats can be found by going up the stairs of the dome and searching the various adjoining rooms.

Appearances
The Forbidden Zone appears only in the Fallout: New Vegas add-on Old World Blues.
