ACE Team has released the official launch trailer for The Mound: Omen of Cthulhu, a cooperative horror game based on Lovecraftian themes [1].

The release marks a significant entry into the psychological horror genre by blending treasure-hunting premises with madness mechanics. By focusing on a cooperative experience, the developer aims to simulate the shared mental deterioration typical of cosmic horror narratives [3].

The game supports up to four players [1]. This cooperative structure is designed to push players through a cursed South American jungle, where the environment serves as a primary antagonist [2]. According to the gameplay overview, the experience emphasizes the tension between exploration and the encroaching psychological instability of the characters [3].

Availability for the title spans multiple platforms to maximize reach. The game is currently available on PlayStation 5, Xbox Series X/S, and PC [1].

Promotional materials released via IGN highlight the game's atmospheric depth and the specific dangers of the jungle setting [1]. The launch trailer showcases the interplay between the four-player team and the supernatural threats they encounter while searching for hidden relics [2].

ACE Team developed the title to showcase a specific blend of atmospheric dread and cooperative survival [3]. The focus remains on the psychological toll of the expedition, a core tenet of the Omen of Cthulhu experience [2].

“The game supports up to four players”

The launch of The Mound: Omen of Cthulhu reflects a growing trend in the horror industry toward 'social' psychological terror. By integrating madness mechanics into a four-player cooperative framework, ACE Team is attempting to gamify the loss of agency and trust, moving away from traditional jump-scare mechanics toward a more systemic form of atmospheric dread.
