Accretion

Accretion is a game in which you control a celestial body and plunder mass from across the universe, growing from a cloud of gas into a supermassive black hole that devours everything. You use abilities to evade and pursue opponents, combining them as your body grows to win the cosmic competition.

Astrophysics and mass

The game calculates interactions between celestial bodies using physical rules. Small bodies orbit larger ones, mass distorts spacetime, and gravitational slingshots propel bodies to high speeds. Black holes accrete mass, while collisions create deadly breaches; supermassive black holes emit sweeping jets. Magnetic fields and gravity from higher dimensions can influence lower-dimensional universes, and dimensional reduction can pull all celestial bodies into one-dimensional space.

Orbital calculations are primarily based on Newton's law of gravitation, while space distortion follows relativistic rules. Real-time physical computations control every mass particle, and the morphology of accretion disks accounts for gravitational lensing. As you plunder mass, its movement follows complex, changing trajectories, and visual effects develop according to the physical rules and the mass you acquire.

Life and technology

Intelligent life emerges amid celestial collisions and exchanges of mass. When the technological civilization that calls your body its homeworld reaches the space age, it provides support through an enlarged sphere of gravitational influence, greater movement speed and rapid repairs to your mass breaches. It can also use virtual decoys and foldspace wormholes, and deploy trap mines and railguns against your targets. The lifeforms fight for their own survival, not to guarantee your victory, and can profoundly alter the universe's laws.

Levels and open universes

Challenge levels have distinct features and objectives. Open-universe scenes are procedurally generated, letting you explore without boundaries in any direction. Your actions also affect mass transfer between other celestial bodies, shaping the course of the universe.

Abilities and combat

As your celestial body grows, you gain abilities. You use and combine them to evade and chase opponents, defeat powerful enemies and pursue victory in the cosmic competition.
