Evaluation

Narcosis launched on March 28, 2017 as a complete, self-contained narrative horror game. In the months following launch, Honor Code shipped several patches addressing bug fixes, balance adjustments, and VR controller support (Oculus Touch). On the game's one-year anniversary, the developer released a bonus DLC package called "Raptures of the Deep" — a free bundle of supplementary materials including the 15-track ambient soundtrack, an in-universe survivor novel, and a radio interview. After a brief delay for Valve approval, this anniversary DLC became fully available on April 9, 2018. The developer explicitly described this content, alongside the game itself, as comprising the "complete Narcosis experience." No further content has been announced or shipped since that date. The June 2024 post from the Narcosis Steam page was a cross-promotion for an entirely new game (AI Confidential) being developed by some of the same creative team — it contains no indication of new Narcosis content. The game launched as a finished narrative product and has not received any content updates since April 2018.

About this game

Survival, 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.

This first person survival story unfolds from inside a half-ton, high-tech dive suit — a “walking coffin." Influenced and inspired by a growing appetite for unconventional horror and narrative-driven games, Narcosis is rooted in reality, but steeped in the surreal.

Features:
  • Pressure Kills: High-stress situations accelerate oxygen intake, distorting sight, sound, space and time.
  • Hostile Waters: A knife, flashlight and flares are essential to surviving the nightmarish flora and fauna of the abyss.
  • Phantom Narrative: The survivor’s account unfolds in inexplicable ways alongside the player’s journey.
  • Beyond Good and Evil: No shadowy organizations or eldritch terrors, only primal fears and human limits.
  • Abyssal Ambience: A haunting soundtrack includes a closing theme from celebrated composer Akira Yamaoka (Silent Hill series)
  • Terror Verite: Primal fears — darkness, confinement and isolation — take on new levels of immersion when experienced in VR.

About Honor Code:
Based in France and California, Honor Code’s collective resume includes such games and series as Assassin’s Creed, Dead Secret, Metal Gear Solid, Remember Me, Republique, The Silent Age, and Silent Hill.
