The Mound: Omen of Cthulhu

The Mound: Omen of Cthulhu is developed by ACE Team and published by Nacon. It released on July 15, 2026, for Windows via Steam, alongside PlayStation 5 and Xbox Series X|S. Inspired by the works of H.P. Lovecraft, the game sends up to four players into a cursed sixteenth-century jungle in search of buried riches, where reality itself starts to unravel the deeper they go.

About the Game

Each expedition begins aboard the galleon Tempestad, where players sign a contract with the captain, split starting gear among the team, and choose which region of the jungle to explore next. Once on land, survival depends on careful resource management rather than firepower, since gunpowder and supplies stay limited and every encounter can turn deadly fast. The deeper a group pushes, the greater the risk, and the greater the potential reward waiting to be hauled back to the ship.

What separates The Mound from typical co-op horror is its madness system. As sanity drops, the jungle begins to distort each player’s individual perception, meaning teammates can no longer fully trust what they see or hear, even from each other. Spatial voice chat reinforces this tension, letting threats be heard before they’re seen. Runs typically last around twenty minutes, rewarding disciplined preparation and clear communication over reckless aggression, since knowing when to retreat to the Tempestad often matters more than clearing every threat in the jungle.

Key Features

4-Player Co-op Expeditions: Form a team of explorers, split starting gear, and choose which part of the cursed jungle to search for treasure next.
Individual Madness System: Sanity drops separately for each player, warping personal perception and sowing paranoia within the group as hallucinations differ from person to person.
Resource-Driven Survival: Limited gunpowder and supplies force careful planning, since combat is dangerous and personal survival often matters more than fighting.
Spatial Voice Chat: Proximity-based audio lets players hear jungle threats before they see them, reinforcing tension throughout every expedition.
