Big MT (Pre-War Research Entity)

Corporations · Source: Fallout: New Vegas Old World Blues DLC in-game lore and terminal entries

Overview

Big MT, the Big Mountain Research and Development Center, was a secretive pre-war research facility hidden beneath a mountain in the Mojave. Its scientists, the future Think Tank, pursued forbidden science across every field. The facility's work created some of the wasteland's most bizarre creatures and technologies.

History & Pre-War Operations

Big MT operated under government patronage, attracting brilliant and unethical scientists who conducted experiments without oversight. Its researchers, including Dr. Mobius, Dr. Klein, and Dr. Borous, pursued projects in genetics, robotics, and weapons. The facility survived the war sealed beneath its mountain, its scientists uploading their minds into robotic chassis.

Products & Technology

Big MT's projects included the creation of Cazadores (mutated wasps), Nightstalkers, and other genetic chimeras; advanced energy weapons; experimental implant technology; and research on the Cloud. The facility developed teleportation, force fields, and weaponized biological agents. Its technologies were centuries ahead of the rest of the wasteland.

Post-War Legacy

After the war, the Think Tank continued its experiments from the sealed facility, targeting wastelanders for its research. Big MT's creations, including the Cazadores and Nightstalkers, escaped into the Mojave and became ecological disasters. The Courier's confrontation with the Think Tank in Old World Blues revealed the facility's full horrors.

Notable Appearances
