The Mound: Omen of Cthulhu turns your teammates into the real horror

GAMING NEWS Cleonidas - about 1 hour ago

Following a series of trailers and gameplay overviews revealed during the Nacon Connect 2026 period earlier this May, The Mound: Omen of Cthulhu has quickly become one of the most intriguing horror titles heading into this summer. Rather than relying purely on jump scares, the game stands out thanks to a much more unsettling idea: turning your own teammates into the source of fear.

Nacon’s upcoming co-op horror game is drawing attention with its paranoia-driven gameplay

Developed by ACE Team, the studio behind the bizarre worlds of Zeno Clash and Clash: Artifacts of Chaos, the game is officially launching on July 15, 2026 for PC, PS5, and Xbox Series X|S. Pre-orders have already started rolling out across several digital storefronts following the game’s appearance at the Nacon Connect Showcase for 2026.

Set in a cursed South American jungle inspired by Lovecraftian horror, the game follows a group of explorers searching for ancient ruins and hidden treasures. At first, the mission sounds straightforward enough: survive the expedition, recover valuable relics, and make it back alive. But the deeper players venture into the jungle, the more reality itself begins to break apart. That’s where The Mound: Omen of Cthulhu reveals what makes it so different from many other co-op horror games on the market.

Instead of focusing entirely on combat or nonstop jump scares, ACE Team is building the experience around a sanity system that slowly erodes each player’s perception of reality. As characters begin losing their grip, every member of the team may start seeing completely different things:

strange creatures visible to only one player
distorted sounds and environments
teammates appearing as monsters
paranoia slowly destroying trust within the group

That mechanic creates the kind of tension few multiplayer horror games manage to achieve. Players are not only trying to survive whatever lurks in the darkness, but also constantly questioning their own senses. One moment of panic could easily turn an entire team against itself. It’s also one of the reasons the project has generated so much curiosity online, especially now that the co-op horror genre is becoming increasingly crowded with similar-looking games.

Beyond its paranoia-driven gameplay, the game’s atmosphere is also receiving positive early reactions. Dense jungles, forgotten ruins, and a heavy dose of cosmic horror give the experience an eerie identity that feels genuinely unsettling in the best way possible. Some players are already comparing its potential for chaotic multiplayer moments to Lethal Company, particularly if the hallucination system remains unpredictable enough after launch.

Of course, there are still a few concerns surrounding the project, especially regarding combat, as the current gameplay footage suggests the gunplay may be fairly simple. Still, with release now only a few months away, The Mound: Omen of Cthulhu already looks like one of the most interesting horror games to keep an eye on this summer.

With its focus on paranoia, mistrust, and psychological tension between players, The Mound: Omen of Cthulhu has the potential to become one of the most unique co-op horror releases of 2026.
