Big MT

Fallout: New Vegas guide · Starting Old World Blues DLC
← All areas in this guide

You arrive in the Big MT crater via a crashed satellite drive-in movie projector and immediately have your heart, brain, and spine surgically replaced by the Think Tank scientists. To return to the Mojave Wasteland, you must complete research tasks, recover stolen personal items, and confront Doctor Mobius at the Forbidden Zone. The main base of operations is The Sink, which acts as a central player home with interactive, upgradable personalities.

Tips

  • Bring plenty of pulse slugs, pulse grenades, or the Paladin Toaster, as almost all difficult enemies in the crater are mechanical.
  • Upgrade the Sink personality modules as soon as you find their holotapes to unlock water purification, crafting converters, and plant cloning.
  • You cannot leave Big MT and return to the Mojave until you finish the main questline of Old World Blues.
