Narcosis 

Narcosis is a first-person survival story after an industrial catastrophe. The game is all about survival and horror at the sunless depths of the Pacific Ocean. Stranded on the seafloor with low light and few tools, an industrial diver takes desperate steps to surface before his oxygen — and sanity — give out. Influenced and inspired by a growing appetite for unconventional horror and narrative-driven games, Narcosis is rooted in reality, but steeped in the surreal.
