The Borehole is an entirely underground mine sector, featuring a lava pit, numerous caverns flooded with muddy water, and heavy industrial machinery. The highlight of this area is the huge bore that the Strogg use to power up their excavations and equipment.
One of the machines powered by the bore is a large elevator that connects to two separate sections of the Drilling Area.
