Read full description
This is an impressive and unique game. You will control your own celestial body, plundering mass in the universe, evolving from a cloud of gas into a supermassive black hole that devours everything.
Astrophysics is the rule of the game
The game uses real physical rules to calculate the mass interactions between celestial bodies, and you will witness:
Spacetime distorted by mass
Small celestial bodies orbiting larger ones
The gravitational slingshot effect propelling bodies at high speeds
The unique accretion phenomenon of black holes
Celestial collisions creating deadly breaches
Supermassive black holes emitting sweeping jets
Influencing lower-dimensional universes through magnetic fields and gravity from higher dimensions
Dimensional reduction pulling all celestial bodies into one-dimensional space
All physical calculations are precisely balanced between gameplay and academic rules:
Orbital calculations are primarily based on Newton's law of gravitation
Space distortion calculations are based on relativistic rules
Every mass particle is controlled by real-time physical computations
The morphology of accretion disks fully considers the gravitational lensing effect
In an ever-changing environment, the motion of mass will exhibit extremely complex trajectories. As the plundering war escalates, the simplest particle effects at the beginning of the game will evolve into a torrent spanning the entire universe. This is a game where the visual effects cannot be predicted in advance, as everything depends solely on the physical rules and the mass you plunder.
Life Rewrites the Laws of the Cosmos
Intelligent life will arise amid celestial collisions and exchanges of mass. When the technological civilization that calls you its homeworld enters the space age, you gain unprecedented, formidable support:
An enlarged sphere of gravitational influence
Higher movement speed
Rapid repair of your mass breaches
Virtual decoys and foldspace wormholes
They even deploy trap mines and railguns to strike your targets directly
They do not fight to guarantee you victory in this cosmic race, but for their own survival. The lifeforms emerging in the latest version will profoundly rewrite the laws of the universe, delivering an experience unlike anything before.
Distinctive game levels and open scenes
The game offers a series of challenge levels with unique features and different objectives, and the open universe scenes are entirely procedurally generated. You can explore infinitely in any direction, with no boundaries. Your actions will also have a significant impact on the mass transfer between other celestial bodies, determining the course of the entire universe.
Strategy and action gameplay
As your celestial body grows, you will gain various abilities. In the midst of evading and chasing actions, you will need to utilize or combine these abilities wisely to defeat powerful opponents and achieve victory in the cosmic competition.
