Lower Underrail is a huge derelict urban area consisting of over 60 zones between major locations. Above it is Upper Underrail, below it are Lower Caves and further down are the Deep Caverns.

Some caves are higher up and directly connected to Lower Underrail, these are known as Upper Caves.

Also immediately below Lower Underrail are under-passages, a network of smaller service tunnels and escape routes.

Description

The Lower Underrail was the industrial/military zone of the big underground metro system before things went to hell. It consists of sprawling main tunnels, metro tunnels and beneath them are smaller escape routes and other accessways. Various stations, towns, other settlements, abandoned complexes and industrial facilities reside in the Lower Underrail. Some wall breaches also lead to adjoining Upper Caves.

Lower Underrail is accessible from South Gate Station level 1 exit. Most of the explorable areas are to the north from SGS, but there are a couple of areas to the south, including a wall breach leading to upper caves. However, most of Lower Underrail is initially inaccessible due to cave-ins caused by the recent earthquake. They can be visited later on, once the south metro tunnel is cleared and the player has access to TNT Charges.
