Inspiral: Echoes of Gravity (AppID: 3638420)

In 2015, LIGO made the world’s first direct detection of gravitational waves with the event GW150914, confirming for the first time in history the existence of binary black hole systems.

In most space-themed games, you pilot a spaceship or colonize planets. But in this game, you become a celestial body. Start as a lonely asteroid, grow by absorbing smaller objects, and evolve step by step—from asteroid to planet, to star, and ultimately to a black hole that devours everything. All of this unfolds in a vast sandbox universe driven by real physics.

Gain mass by absorbing smaller asteroids and progress through multiple cosmic stages, each unlocking new abilities and challenges:

• As a planet, nurture life and protect your own world;

• As a star, your powerful gravity can capture planets and build your own planetary system;

• As a black hole, nothing can escape your grasp.

Explore freely in a universe governed by authentic gravitational and orbital mechanics, and create your own cosmic system.

Key Features:

• Cosmic Growth System: Evolve from an asteroid to a planet, a star, and finally a black hole, each stage offering unique gameplay and abilities.

• Realistic Physics Simulation: Experience lifelike gravity and orbital mechanics—construct stable planetary systems or trigger spectacular collisions and chaos.

• Dynamic Sandbox Universe: An ever-evolving universe where new celestial bodies and events continually emerge, and cosmic evolution never stops.

• Explore the Binary Black Holes: As the binary black holes grow and spiral toward each other, will you survive—or be swallowed by the void?
