About Aphelion
Aphelion is a text-forward space-horror adventure in which Vale, a rescue medic, boards the survey ship Aphelion-7 ten weeks after it went dark past the heliopause. Told in first-person present tense with painterly scene art and visual-novel dialogue, the game moves compartment by compartment through a dying ship, gathering evidence and reading survivors who may no longer be entirely themselves. Around 21 pen-and-paper puzzles with provable solutions gate progress, spanning logic-gate circuits, ciphers, and constraint locks, and hints cost sanity, a resource that makes the game itself start lying as it drops. Choices persist across the story, two of them irrevocably, leading to six tonally distinct endings tracked across playthroughs.
How rarity is calculated
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison.
- Xbox — Microsoft's published rarity percentage across Xbox players.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
