The Sub Levels

The Sub Levels are buried deep beneath Tier City at the ground level of Old Earth. They are inhabited by the outcasts of Tier City society such as the Rare Earth Activists, Chems, and Mechas.

The Sub Levels can be traversed using the Old Earth subway systems in Speeders.

The Sub Levels can be used to access many abandoned buildings and old structures long since forgotten following the fall of Old Earth.
