Cthulhu's Reach: Devil Reef

From the Devs

The year is 1923. You Owe a Gangster More Than You Can Pay
A tip-off points you toward the cursed seaside town of Innsmouth — and the sunken labyrinth known as Devil Reef. Treasure lies in its depths. So do things that have never been seen by sane eyes. With your crew of desperate fortune-hunters at your side, you descend. Whether you return, and whether you remain yourself if you do, is a different matter entirely.

Descend with Friends. Lose Your Minds Together
Cthulhu’s Reach: Devil Reef is built for 1 to 4 players. The horror is survivable alone. With a crew, it becomes an experience — the moments when a friend’s sanity breaks, when the dungeon shifts, when a run that seemed impossible suddenly clicks. Online co-op with full dungeon scaling ensures that whether you play solo or with three companions, every descent is a fresh reckoning.



No Two Descents Are the Same
Procedurally generated labyrinths mean Devil Reef never plays the same way twice. Each run is shaped by over 100 collectible items across four rarity tiers, a deep weapon unlock and upgrade system, and enemy encounters built around status effects — bleeding, burning, slowed, panicked. Three acts of escalating horror await in the full release, alongside a Daily Challenge mode with a globally seeded dungeon so you can compete against every other delver in the world.



Your Descent Into Madness Writes the Trials
Lose enough sanity and your mind starts fighting back against you. Cross a threshold, and it conjures curses you must face on the next level; enemies grow vicious, rules turn cruel. Pick one. No skipping, no rerolling.
Survive it, and you keep a permanent reward for your trouble. But every curse taken narrows your next choice. Stay sane, and you may only ever face one. Fall all the way into Madness, and there's no choice left at all…
