Forbidden Zone Dome Entrance

The 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. The door to this facility remains locked until the player has spoken with Dr. Klein as part of the quest Old World Blues.

Workshop
The workshop area is comprised of a single, very large room that appears to occupy most of the inner volume of the building's dome. In the center is a large cargo elevator, on which rides the X-42 giant robo-scorpion. Around the perimeter of the room are several staircases leading to raised walkways and observation rooms, some containing terminals with information on the giant robo-scorpion. This information can be used to damage or disable the scorpion without direct attack by the player. One terminal in particular, located on the highest catwalks in the room, says that it can be used to shut down the giant robo-scorpion remotely, but actually resets the giant robo-scorpion to be friendly to the player, after which it will be somewhat disabled.

Dome
The Forbidden Zone's Dome is similar to The Think Tank's, but in significantly worse condition: the lighting is sickly green, the equipment is rusted, broken, or otherwise mostly unusable, and Dr. Mobius has covered every surface in the main room with intricate scrawls of notes and formulas. In the six smaller rooms located off the upper tier, stored office furniture containing random loot can be found, along with what appears to be Dr. Mobius' private stash of Mentats. Located at the top of the main staircase, in a storage tank, is The Courier's brain.

Behind the scenes

 * The name of the facility is a reference to the 1956 science fiction film Forbidden Planet. Dr. Mobius himself was partially inspired by the movie's main antagonist, Dr. Edward Morbius.
 * It may also be a reference to the "Forbidden Zone" from the movie series Planet of the Apes.

Bugs

 * Upon entering, it is possible to become stuck under the platform nearest the entrance.
