Survive Cosmic Madness in The Mound: Omen of Cthulhu - Deluxe Edition
Venture into a cursed, uncharted continent in The Mound: Omen of Cthulhu - Deluxe Edition, an atmospheric co-op survival horror extraction shooter developed by ACE Team and published by Nacon. Loosely inspired by H.P. Lovecraft’s cosmic horror, this intense adventure challenges squads of explorers to hunt for legendary treasures during the Conquistador era while fighting off unnamable monsters and their own deteriorating sanity.
Fight Unspeakable Horrors and Your Own Mind
In this dark jungle, your perception is your greatest vulnerability. As your sanity drops, you will encounter severe auditory and visual hallucinations that directly impact gameplay and coordination—making it impossible to fully trust what you see or hear. Communication via proximity voice chat is vital as you complete dangerous expedition contracts. Should a teammate fall, they become corrupted, turning against the remaining crew in a brutal test of survival.
Key Features:
- Lovecraftian Co-op Action: Team up with up to 4 players with full crossplay support or brace the madness alone in an oppressive cosmic horror setting.
- Deep Illusion Mechanics: Adapt to a dynamic madness system that distorts gameplay, spawning reality-warping illusions and paranoia.
- Handcrafted Expedition Maps: Explore 18 uniquely atmospheric levels filled with creeping dread, hidden lore, and high-stakes extraction loops.
- Deluxe Edition Content: Dive deeper into the expedition with exclusive launch content, including unique character and weapon skins.
Secure your Steam PC key for The Mound: Omen of Cthulhu - Deluxe Edition today. Compatible with Microsoft Windows and GeForce Now. Rated ESRB M for Mature / PEGI 18 due to intense violence, blood, and gore. Enter the jungle, complete the contract, and make it back to your galleon before madness devours you completely.
