Nuka-World access tunnels

The Nuka-World access tunnels are an underground tunnel system at Nuka-World

Background

Layout
After Nuka-World was conquered by raiders, the access tunnels were used to construct the majority of "The Gauntlet," an enclosed system of deadly challenges for all newcomers entering Nuka-World via the Nuka-Express, built for the raiders' entertainment.

Appearances
The Nuka-World access tunnels appear only in the Fallout 4 add-on Nuka-World.
