While the original mod is intended to create a multilayer bio-pod world, where each layers is connected through alien-bases, our adaption is only using a single layer. In both, bio-pods and alien-bases, are control centers, which will randomly either teleport you to a random place, or attempt to kill you. Also, the pods are known to be a home for dangerous monsters.
The creator of this amazing, but abandoned mod writes:
Loud Walking is a play on the name of an old science fiction movie about an attempt to preserve Earth's endangered life in sealed pods in space. This mod creates pods at about 28 km altitude, with more or less normal terrain inside, including vegetation and minerals. Bridges are provided to move horizontally.
Below the layer of bio-pods, there is big layer of asteroids.
