Introducing KARST-9, the first immersive mystery experience from Ambient Outpost.

November 1987. Deep inside a secret underground facility, maintenance operator Elias Voss begins investigating the disappearance of his predecessor. What starts as a routine assignment gradually reveals troubling inconsistencies in the records and operations of KARST-9.

Combining an illustrated mystery with animated environments, original dark ambient music and atmospheric soundscapes, KARST-9 brings storytelling and ambience together in a standalone experience for Windows and Mac.

EXPLORE THE WORLD OF KARST-9

• 96-page illustrated mystery: Read Elias Voss's field journal directly within the atmospheric experience.

• Three animated environments: Spend time in the Monitoring Room, Lower Transit and Ventilation Tunnel.

• Original music and ambience: Adjust both independently to create your preferred atmosphere.

• More than a reading experience: Leave the environments running while working, reading, relaxing or falling asleep, with an optional sleep timer.

• Standalone illustrated journal: A separate PDF edition in light and dark versions is included.

KARST-9 — Archive 001 is available now in the shop!
