## Overview

Sonus is a multiplayer party game that drops you into a pitch-black world where visibility is a luxury. Developed and published by Uncle Dunc, this casual title blends stealth, horror, and cooperative play into a tense cat-and-mouse chase. The game launched on October 26, 2026, and supports both online co-op and PvP modes, making it a versatile pick for groups who enjoy asymmetric gameplay.

## Highlights

- **Echo-Based Vision**: The only way to see is through echoes generated by your footsteps and your Sonus launcher. This creates a unique sensory mechanic where sound becomes your primary tool.
- **Two Distinct Roles**: Play as a Stone Seeker, trying to locate and retrieve the Sonus Stone, or as a Stone Keeper, tasked with hunting down the Seekers before they escape.
- **Special Echo Abilities**: Passing through certain echoes grants temporary effects, such as slowing down enemies or boosting your team, adding a layer of strategy to movement and positioning.

## Who It's For

Sonus is ideal for players who enjoy social deduction, stealth, and light horror elements without the gore. If you like games like *Among Us* or *Dead by Daylight* but want something more casual and accessible, this fits the bill. It's also great for online co-op sessions with friends, as communication and teamwork are key to surviving the dark.
