The Hadal Blacksite

The Hadal Blacksite is a central location in Pressure, and the setting of the game's main expedition. It is a secret facility where players are sent to secure the crystal from the Crystal Room as part of the "Expendable" Protocol.

Overview

The Hadal Blacksite is an underwater facility constructed by Urbanshade to host developmental research for secret projects and for the containment of anomalies, such as the various Monsters encountered ingame. It is the home of Urbanshade's Hadal Division and N.O.S.T Subdivision, located inside of the veil of The Let-Vand Zone at a depth of 67,320-studs. The site began construction in 1962 and was finished in 1974, with the Ridge being the first part finished.

After the containment breach caused by Sebastian Solace, the Blacksite was left in a state of disarray, with numerous monsters roaming the halls. During the Hadal Blacksite expedition, you play as an expendable prisoner tasked with exploring the Blacksite, securing any loose assets, and retrieving the crystal in exchange for your freedom.
