Borehole

But two, Durajongo is well known for being located against a hyperactive volcano.

Paragon bores deep underground to tap into this volcano in order to make use of its geothermal energy to power the new scientific facility, which they've affectionately named The Borehole.

When you escape as the main character of Burger Barn and Burger Farm, you become aware of just how far-reaching and unhinged these experimental simulations have become and just how massive this borehole really is, spanning multiple levels and hundreds, if not thousands, of captives and staff.
