Remnants of R'lyeh

About this game

Remnants of R’lyeh is a first-person survival horror experience set deep beneath the waves — where madness slumbers, and ancient nightmares stir.

Inspired by the mythos of H.P. Lovecraft, Remnants of R’lyeh thrusts players into the mind of Jason, a deep-sea diver haunted by a disastrous expedition and drawn into a decaying city lost to time and sanity. Trapped in the abyss, Jason must navigate a biomechanical world powered by the flesh of sea monsters, uncover twisted secrets, and confront grotesque abominations born of cosmic terror.

Explore a labyrinthine steampunk metropolis teetering on the edge of reality — where rusted gears grind alongside flesh-bound machines, and the boundary between dream and death collapses. Armed with scavenged weapons and limited sanity, survival hinges on your ability to fight, hide, and piece together a story that was never meant to be told.

Features:

  • A Lovecraftian nightmare brought to life with haunting visuals and immersive environmental storytelling

  • A seamless blend of horror, shooter, and exploration mechanics

  • Sinister AI-driven enemies that evolve with your fear

  • A richly detailed, linear yet atmospheric deep-sea world inspired by Bioshock and Silent Hill

  • Psychological descent into madness with sanity-based narrative progression

Descend into the depths. Face the unknowable. Escape, if you can — but remember: some things should stay buried...

Remnants of R'lyeh

Inspired by H.P. Lovecraft's Great Work. An ancient dark power is calling you and you need to find an exit. Face your greatest fear, fight, hide... you must escape before the underwater city rises...
