Somnius is a chaotic first-person co-op extraction game that plunges up to six players into the surreal, collapsing dreamscape of a mysterious Dreamer. Your mission is straightforward but perilous: locate the Dreamer, guide them to the portal, and escape before the entire dream erases itself. The core gameplay loop revolves around exploration, scavenging, and strategic decision-making under mounting time pressure. As the dream deteriorates room by room, players must manage a constant resource dilemma: collect debris and environmental objects using your vacuum gun, then decide whether to weaponize them against hostile entities or feed them into the portal to buy additional time. This dual-purpose mechanic creates emergent tension, forcing teams to balance offensive capability against survival necessity.

The vacuum gun serves as your primary tool for problem-solving, inventory management, and combat. It can absorb furniture, defeated enemies, and even your teammates—then fire them back out with physics-driven consequences. This creates opportunities for creative cooperation and chaotic moments where a well-timed launch can solve puzzles or turn the tide in combat. The game rewards observation and patience; environments contain hidden layers and interactive details that reveal themselves to attentive players, transforming exploration into a puzzle-solving experience rather than mere loot collection.

What distinguishes Somnius is its dreamlike aesthetic paired with grounded mechanical depth. The visual design contrasts nocturnal shadows with bursts of luminescence, creating an atmosphere that feels both somber and curious. The environments suggest histories etched into stone and arcane architecture, establishing a world where every detail appears intentional. This atmospheric presentation combines with the physics-based scavenging mechanics to create a distinct identity within the extraction game space.

Somnius appeals to players who enjoy cooperative horror experiences with a puzzle-solving bent, similar to titles like Lethal Company and R.E.P.O. but with its own dreamscape twist. The game demands communication, resource management, and creative problem-solving from teams. It's designed for players who appreciate emergent gameplay moments, environmental storytelling, and the tension of racing against a collapsing world. The chaotic, physics-driven mechanics ensure that no two runs play identically, encouraging replayability and experimentation.
