In This Co-Op Horror Game, What You Don’t Know Will Hurt You, Actually

Co-op horror games are all the rage these days, but standing out in the genre means doing something different. The Mound: Omen of Cthulhu has carved out its unique angle. This four-player Lovecraftian horror experience drops you and up to three friends into a forest teeming with cosmic horrors, where your goal is to collect loot and escape with your life. While it might remind players of Lethal Company, The Mound avoids being just another copycat by bringing fresh ideas to the table.

A Beautifully Crafted World

One of the standout features of The Mound is its visual design. Rather than going for the "friendslop" aesthetic that many co-op horror games opt for, The Mound leans into a more detailed and photorealistic look. This is especially evident in its environments, which are both breathtaking and eerie. The forest is filled with zombie-like creatures, giant insects, and ominous birds that seem to herald doom. Despite the horror elements, the setting is visually stunning — a testament to the work of the relatively small studio, Ace Team.

A Unique Hallucination Mechanic

The real innovation, however, lies in The Mound's hallucination mechanic. Each player in a group can experience their own unique hallucinations, making the forest feel alive and responsive to your progress. The deeper you go and the longer you stay, the more the environment seems to toy with your mind. You might see things that aren't there or fail to see things that are, adding a layer of unpredictability and paranoia to the gameplay.

One clever application of this mechanic is when a player is tripping so badly that they see their allies as monsters. While this can be manageable when you're alone and have time to sort through the illusion, it becomes a nightmare in the middle of a chaotic moment. Imagine swinging your sword at a friend who looks like a ghoul — and not having time to question it.

A Strategic Approach to Survival

Though The Mound is presented in first-person and includes guns, it’s not a traditional first-person shooter. In fact, the noise you make can awaken the forest and bring more threats your way. This means that shooting is a last resort — not only because you need to stay quiet, but also because the guns are slow and have limited ammo. The game encourages stealth and careful movement, making every decision crucial to your survival.

A Familiar Yet Fresh Formula

In a departure from the usual Lethal Company formula, The Mound doesn't use procedurally generated levels. Instead, the levels behave more like those in Left 4 Dead, where the layout is largely consistent from round to round, but smaller elements change to keep things interesting. The developers made this choice intentionally, aiming to strike a balance between keeping players from memorizing the maps and still giving them that feeling of being lost in the woods.

Beyond Loot: A Richer Narrative

Collecting loot isn't the only objective in The Mound. There are also story-related items that can be found, which unlock new maps and reveal more about the game's lore. Some of these maps take you out of the forest, but the hallucinations remain. Players aren't required to go far in any given round, and sometimes it's best not to — chasing after story items can give the forest more time to become sinister, eventually unleashing boss monsters that can only be avoided, not defeated.

A Mind-Bending Experience

From my limited preview, The Mound shines in its ability to keep players guessing. The rules of the world are deliberately unclear — you never know what a particular fungus will do when you eat it, or how hallucinations will affect your perception. This uncertainty adds to the game's psychedelic, mind-bending nature. There were moments in my demo that I don’t want to spoil, as they hinted at some truly horrifying implications for the world the game is set in.

The developers have made it clear that they don't plan to explain much about the forest's rules before the game's July 15 launch. Instead, they want players to dive in and try to piece things together themselves, both as a group and as a wider community on forums like Reddit and Discord. It's like one big, shared drug trip, where the comedown could cost you everything.
