About the game
In 1983 a satellite built to kill is launched into space and later abandoned to history. By 2041 it reawakens, and everything in Earth's orbit is suddenly fair game. One shot sets off a chain reaction of wreckage, and you are the one who brings about the Kessler syndrome in this brief pixel-art incremental title. Periapsis Works developed and published it, and it was released in 2026.
Did you know?
Kessler syndrome is a real concept proposed in 1978 by NASA scientist Donald Kessler: cascading collisions between orbiting objects could fill low Earth orbit with debris.
