About Heliopedia
Heliopedia is a planet-terraforming game in which you control a solar system and shape its planets. You use a pseudo-scientific chemistry system to discover combinations, then find out more about each discovery in the Heliopedia, an in-game encyclopedia.
Discoveries and planets
A friendly sun at the center of your universe gives you new items when you make discoveries. Feed it a favorite snack, such as coal or ashes, and it spits out a new planet to terraform. You can create ocean planets, grass plains and rain forests, or cause wildfires, volcanoes and thunderstorms.
Biomes and life
Planets can have 11 main biome types, along with diverse insects, plants, animals and trees. The Heliopedia contains 100 entries to discover. The game offers 2–3 hours of play time.
