Developer ACE Team and publisher Nacon released an official gameplay showcase trailer for the co-op action-horror adventure "The Mound: Omen of Cthulhu" today.

The reveal provides the first deep look at the game's mechanics and atmosphere, signaling the project's transition from announcement to a concrete launch window. As a cooperative title, it targets a growing market for social horror experiences.

Art director Edmundo Bordeu presented the gameplay during the Nacon Connect 2026 showcase [1]. The footage highlights the title's focus on atmospheric horror and cooperative strategy. According to the showcase, the game supports a maximum of four players in co-op [2].

The title is scheduled to launch on July 15, 2026 [3]. It will be available on PlayStation 5, Xbox Series X|S, and PC via Steam [4].

Bordeu and the ACE Team focused the presentation on the game's environmental storytelling and the specific challenges players face while navigating the cursed jungle. The gameplay showcase was designed to generate excitement by demonstrating how the four-player system integrates with the horror elements of the Cthulhu mythos [1].

Nacon Connect served as the primary platform for the reveal, utilizing a virtual event to reach a global audience. The showcase emphasized the technical capabilities of the current-generation consoles and PC to render the game's detailed, oppressive environments [4].

By targeting four-player cooperation, ACE Team is positioning the game to compete with other social horror titles, leveraging the recognizable brand of Cthulhu to attract both genre fans and general gamers on current-gen platforms.
