The Mound: Omen of Cthulhu is a first-person co-op horror game for up to four players, inspired by H.P. Lovecraft's novella of the same name. Set in the 1600s, your crew of conquistadors boards a galleon and ventures into a cursed South American jungle in search of a legendary underground city and unimaginable riches.

The jungle is your first enemy. Dense vegetation slows movement — cut through it with a machete, but the noise draws creatures. Wet gunpowder won't fire when you need it most. Caves offer shelter but hide the most valuable — and most dangerous — discoveries. As you push deeper, Lovecraftian creatures warp your perception, triggering hallucinations and sowing paranoia between teammates. Trust erodes. Madness creeps in.

Key Features: • 1–4 player co-op first-person Lovecraftian horror expedition • Sanity and hallucination system — reality warps, teammates become suspects • Environmental survival: wet gunpowder, dense fog, hostile jungle terrain • Mission prep aboard galleon — select weapons, tools and loadout before each run
