The Big MT west tunnel is a location in the Big MT in 2281.


The entrance leads to a subway tunnel. There is a locked door (easy) to the right from the entrance that leads to a small room. There are two doors to the right leading to a network of maintenance tunnels filled with protectrons scaled to the player character's level, along with a unique protectron named the Custodian. The tunnels end with a locked door (hard) that leads into a subway tunnel, which is caved in on both ends. There is a saturnite fist inside of the tunnel, next to a skeleton.

Notable loot


  • From the outside the entrance grate is slightly lifted (granting entrance) but when inside it is closed.


The Big MT west tunnel appears only in the Fallout: New Vegas add-on Old World Blues.
