About Remnants of R'lyeh
Remnants of R’lyeh is a first person survival horror game inspired by the cosmic horror of H.P. Lovecraft. Play as Jason, a deep sea diver drawn into a forgotten realm hidden beneath the ocean.
Explore decaying underwater cities, scavenge for resources, solve puzzles, and fight grotesque creatures as you descend deeper into a biomechanical nightmare of rusted machinery, Victorian technology, and ancient horrors.
Survive the Abyss
Fight grotesque creatures with firearms and melee weapons, search for supplies, and conserve your resources. Exploration, combat, and environmental puzzles are woven together throughout your journey.
Above and Below the Water
Explore handcrafted environments both on land and beneath the ocean, from abandoned streets and industrial ruins to submerged structures lost in the abyss. Each location offers new dangers, secrets, and paths to uncover.
A Biomechanical Nightmare
Descend into a distinctive Lovecraftian setting where Victorian machinery, rusted steel, and living flesh have been fused together. Explore the remains of a civilization shaped by the ocean and forces far beyond human understanding.
