Detailed walkthroughEdit

The Courier can begin this quest by speaking to Dr. Klein, where the good doctor will tell them that it's time to go to the Forbidden Zone and get their brain back. He also asks the Courier to deal with Dr. Mobius. Optional speech checks are available:

The player character should begin by traveling to the Forbidden Zone, once there, the Courier will encounter several robo-scorpions surrounding the entrance. After dealing with them and entering the zone itself, Dr. Mobius will release his most powerful creation, the X-42 giant robo-scorpion.

  • Enter the room further to the right with stairs that leads to a terminal, which gives the player character the option of activating the X-42 backup generator, or overloading it and causing some damage.
  • Enter the room to the left and use the terminal to access turret controls (Average lock) to turn them upon the X-42 giant robo-scorpion. Although they will not be sufficient to destroy the X-42, they will cause a lot of damage.
  • Activating the protectrons in the room to the right from the dome's entrance will distract the robot long enough to get to the shutdown terminal or other terminals.
  • Enter the balcony room on the far left side of the zone from the entrance, that contains a computer terminal (Very Hard lock). If hacked, it gives the option to permanently disable the X-42 giant robo-scorpion. Access to this room is via the stairs on the far left side of the room. If the Courier lacks the necessary Science skill, the password to the computer is on a holotape to the left of the leftmost protectron bay.
  • Alternatively, if the Courier has the Robotics Expert perk, they can sneak up and disable it, but the X-42 giant robo-scorpion will restart itself after a set amount of time has passed.

After defeating it, the Courier must confront Dr. Mobius. To do so, take the stairs to the left of the entrance and enter the door on the right. There they will meet Dr. Mobius, who, strangely enough, is not hostile.

Here there are two choices: reason with him or kill him.

Option 1: Reason with Dr. Mobius

If reasoning with Dr. Mobius is chosen, he will direct the Courier to their brain where they must convince it to return. Optional speech checks are available with him:

Option 2: Fight Mobius

If the Courier chooses to fight Mobius, Dr. Mobius will release 5 MK4B robo-scorpions. They will need to defeat Mobius and the robo-scorpions to continue. 1066 XP will be given for defeating Mobius.

Once Dr. Mobius is dealt with, the Courier must then speak to their brain, and convince it to join them again. Having high Medicine, Speech or Science will give them a significant advantage and make the dialogue much easier. The use of the unique dialogue provided by Confirmed Bachelor/Cherchez La Femme/Black Widow will result in a somewhat humorous, if mortified response from the brain that does not help much. Talking to the brain and convincing it to help in the final quest stage will grant the Make up Your Mind achievement/trophy. Optional speech checks:

  • Speech 75 (x2). Choosing to have the brain reinserted into the Courier's body will result in replacing the Brainless perk with the Big Brained perk, which yields +10% DT (Damage Threshold).

After acquiring the brain, the Courier needs to speak to Dr. Mobius again. He'll tell them more about what the Think Tank is all about and suggests dealing with them, instead of him. The choice is up to the Courier.

After making the choice, the Courier needs to return to the Think Tank. There they have the option of using the Sink's Auto-Doc to retrieve their original heart and spine.

  • Choosing to replace their original heart results in replacing the Heartless perk with the Cardiac Arrest "perk" (healing chems are 50% more effective)
  • Choosing to replace their original spine results in replacing the Spineless perk with the Reinforced Spine "perk" (STR and DT bonuses doubled (+2))
  • If the Courier decides to leave their heart and spine, they can be replaced at any time they wish. Then they must choose to deal with the 5 members of the Think Tank through violence or reason.

Option: Reason with the Think Tank

For those wishing to reason, the speech checks are:

Option: Fight with the Think Tank

The Courier must destroy all five members of the Think Tank.

After completing the quest, and watching the ending slide show, the Courier is given the Big Mountain Transportalponder!. This will allow one to return to the Big MT via The Sink balcony at any time, or from Big MT to the Mojave Drive-in, although using it is limited to locations within the Mojave Wasteland, and cannot be used in areas such as the Strip or while in combat. Furthermore, upon completion, all active personalities in The Sink will cheer for the Courier's victory, with a particularly drawn-out and rambling congratulations from Blind Diode Jefferson.

After the slide show ends, (and the Courier convinced the brain to come back), the brain will be located in the far left room, (where the heart and spine have been stored). They will then be able to re-transplant and de-transplant their brain later at any time or leave it in the storage facility. Doing so will change brain, heart, and spine-related perks.

BugsEdit

  • ps3Icon ps3 xbox360Icon xbox360 pcIcon pc When the brain is asked if it wants to be reunited with the Courier, choosing the compromise option, the second choice, 'So, what, you'd rather just stay here? Never leaving that tank of... whatever that stuff is?', will result in a neverending loop of the brain talking about the quests. This only seems to happen if the player has completed Come Fly With Me and That Lucky Old Sun. If this happens, reload the autosave where the player entered Mobius' room and pick alternate dialogue options. [verified]
  • pcIcon pc xbox360Icon xbox360 After finishing this quest by either killing or talking to the doctors in the Think Tank, the game may crash as the player tries to leave. This bug occurs in hardcore mode when the player has a hunger greater than zero. If this is the case, turning hardcore off temporarily may allow to continue bug free to the end. [verified]
  • xbox360Icon xbox360 When speaking with Dr. Klein at the end of the DLC, some dialogue may repeat when the other brains are trying to keep the player alive. [verified]
  • xbox360Icon xbox360 If the Forbidden Zone is entered without first killing the robo-scorpions outside, upon exiting, all of the robo-scorpions will be gone. [verified]
  • pcIcon pc ps3Icon ps3 If certain choices are made in dialogue, it is impossible to reason with Mobius and killing him becomes the only option, even if the correct skill checks are completed. [verified]
    • A possible fix for this bug involves a repair check to fix Mobius' monitor, which can re-initiate the dialogue path needed to avoid killing Mobius.
  • ps3Icon ps3 pcIcon pc While entering the Forbidden Zone, the X-42 giant robo-scorpion may not attack unless it is approached. This will remain the case even when attacking the X-42 giant robo-scorpion. [verified]
  • ps3Icon ps3 xbox360Icon xbox360 When the protectrons inside the Forbidden Zone dome are activated, a seemingly unlimited number of them may keep attacking the X-42, creating an effective distraction when attempting to destroy the X-42 giant robo-scorpion. [verified]
