Nitrogen Narcosis

Nitrogen Narcosis is a co-op deep-diving horror game set in abandoned facilities, both sinking and already sunk. You and up to seven other employees wear cheap deep-dive suits and recover old materials to bring back to your captain’s submarine. As you descend, symptoms of nitrogen narcosis cause hallucinations while you try to survive the creatures and mutations inside.

Explore the facilities

Facilities range from the Shallows, where the surface is still visible and the structure is not flooded, to the Deep, where light is scarce, facilities are larger and danger is widespread. Each facility has a layout that changes with each play session. They contain key-card doors, automatic doors, secondary airlocks and doors that may be dangerous to open.

Creatures

The facilities are home to sharks that have found their way inside, crabs that hoard loot and mutant horrors such as specimen 2626.

Arctic Circle

The Arctic Freeze Update adds a location in the Arctic Circle, a creature and new loot.
