The sun is dying. One billion minds sleep below. You are HALCYON, the caretaker AI — dismantle a solar system, planet by planet, to build them an Ark. An incremental that ENDS: 4–6 hours, two endings, no infinite grind. Every world you consume stays gone. Even the Earth. Especially the Earth.

About this estimate
This range compares your graphics hardware with the game's requirements and expected performance profile. Estimates depend on your saved specs on WhatALaunch — they are not a single FPS figure that applies to everyone. Use them as a practical guide, not a guaranteed benchmark.
Actual performance can vary with graphics settings, drivers, CPU, memory, cooling, game updates, and background activity.
