Fallout: New Vegas locations project
Big MT north tunnel
The north tunnel is a subway tunnel shaft with a door on the right of the entrance of the tunnel. Inside there is a hole in the floor, leading down into a subterranean cavern. The hole is guarded by an overclocked turret and covered with a force field that requires an upgraded sonic emitter to bypass. The cavern leads down a short ways with a group of crates with miscellaneous loot at the end.
- Light Switch 02 personality tape, on shelf behind the door to the right of the entrance.
- A LAER at the bottom of the cave in the tunnel.
- Down the shaft there are 5 mutant cave fungus plants you can harvest.
- This is most likely the location where Elijah punched an escape route out of the Big MT using a train.
- On the left front wall of the arch there is an Old World Flag painted in white, left by Ulysses.
