Belgian indie studio Badass Mongoose is preparing to take players on a moody, mind-bending journey with Helix: Descent N Ascent, an atmospheric puzzle-adventure steeped in stark black-and-white visuals and emotional storytelling. The game is set to appear during Steam Next Fest (February 23 – March 2), with a playable demo launching in the second week of February. Early demo codes are also available for those who want a sneak peek ahead of time.
From the first glance, Helix: Descent N Ascent stands out thanks to its distinct monochrome art style, inspired by 1980s black-and-white indie comics, 1990s manga, and 1970s Franco-Belgian comic art. The result is a world built entirely around the tension between light and darkness, where every shadow and highlight feels intentional.

That atmosphere is further elevated by an evocative soundtrack composed by Jim Guthrie, known for his work on Sword & Sworcery, Nobody Saves the World, and Below. His music plays a central role in shaping the game’s dreamlike tone, turning exploration and puzzle-solving into a reflective, almost meditative experience.

About the Game
In Helix: Descent N Ascent, players awaken in a forgotten, disembodied world where ancient forces lie dormant. As you descend deeper into Helix, you’ll unlock and combine mysterious abilities, each one opening new ways to interact with the environment and uncover the secrets of a lost civilization.
You won’t be entirely alone for long. Along the way, you encounter a strange doppelganger — a being that looks exactly like you, yet constantly seems to oppose your actions. Whether this figure is an ally, an enemy, or something in between is one of the many questions Helix asks as it explores themes of identity, solitude, and connection.
