Developer 11 bit studios has released a playable demo for The Alters, their long-awaited sci-fi psychological thriller game.

The new playable demo for The Alters is now available on all platforms across Windows PC, Xbox Series X|S, and PlayStation 5.

Here’s a rundown on the game, plus a new trailer:

From the creators of the critically acclaimed This War of Mine, The Alters invites players into an intense sci-fi survival challenge—one that Jan can’t face alone

After crash-landing on a hostile planet under a blazing sun, Jan must survive in a high-tech mobile base designed for a crew he doesn’t have. His luck changes when he discovers Rapidium, a resource that, when paired with the Quantum Computer, lets him create Alters—alternate versions of himself based on changing the pivotal decisions from his past.

The Alters aren’t just workers—they’re individuals with their own skills, emotions, and motivations. While essential for keeping the base functional, crafting tools, and mining resources, their distinct personalities can spark tension. Despite their differences, they share a common goal: survive, escape, and rely only on themselves.

The game explores the timeless question: “What if I had chosen differently?” This core theme fuels a deeply personal and thought-provoking narrative as players navigate Jan’s struggle for survival.

The Alters is set to launch sometime in 2025 for Windows PC (via Steam, GOG, and the Epic Games Store), Xbox Series X|S, and PlayStation 5.
