It’s a first person survival crafter with very strange science vibes.

Imagine you were a scientist on your first day at Black Mesa when Gordon caused the Lambda Incident (this is a Half-Life reference for those uninitiated) and in a kind of Subnautica style need to scrounge the environment for resources to research and crafted supplies and equipment to use to survive and explore further while encountering invaders as well as what are essentially SCPs or Objects of Power (Control/Alan Wake) throughout the facility and other environment all in the hopes of trying to escape with your life.
