Afterdepth

Afterdepth is an exploration, survival and technology-progression game set in a post-apocalyptic underground world. When contact with Bunker 09 is lost after a mysterious incident, you play as Dr. Kellan, a researcher stationed in Bunker 08, and investigate what happened. What begins as a routine emergency leads to a more disturbing mystery.

Investigate the bunkers

You explore abandoned facilities, recover forgotten records and follow evidence left by those who came before you. Each bunker reveals another part of the larger mystery.

Explore and survive

The underground world consists of procedurally generated cave systems, with hidden structures, rare resources and increasingly dangerous depths. You manage oxygen, power and resources as you navigate hazards including cave-ins, falls and suffocation.

Research new technologies

Scan resources and collect scientific data to unlock technologies through a research tree. You can upgrade your equipment to prepare for expeditions into deeper, more hostile regions.

Build and automate

Restore abandoned bunkers, construct habitats, generate power and produce oxygen to support larger operations. Automated excavators, industrial refineries, storage silos, support drones and logistics systems help process resources and extend your reach. The game also features modular underground habitats, the Mach1 companion drone, and dynamic material and liquid simulation.
