Biome

Each planet usually has a commonly formed Terrain that has the same type of decorator or color; these are called biomes, and they’re made to make it easier for players to differentiate their locations. Please do note that:
 * Not all playthroughs guarantee you that all of these biomes be present
 * Names given to these biomes are just a placeholder, hence it's unofficial
 * Detailed information regarding biomes can be found within the planet's pages
 * If you found a biome that isn't listed here, please create a new discussion next to the edit tab, including at least one screenshot of the said biome.

 * Flatlands: Flat and rocky area, great for building bases, Research Items and organics resources are rare to be found.
 * Towering Forest: Very tall trees occasionally appear, and a good amount of Research Items can be collected from here. Great starting area for new players.

 * Green Earth: The underground layer of Terran, named after it's dark green appearance. Hazardous Flora such as Spikers and Exploders appear commonly in here.

Barren

 * Craters: Barren has gigantic craters that can be found all over the surface, with a high chance for crashed satellite parts to congregate around or inside of them. There is a chance of larger craters consisting of many smaller craters inside, where entrances into deep caves can be found.

 * Red Sands: The underground layer of Arid, resources rarely appear around here.

Tundra

 * Icy Plains: Ice spikes occasionally form around in a cluster. Plenty of wind, which is a perfect place to plant your wind turbines.
 * The Tundra: Small patches of organic resources may appear, lots of rocky formation.
 * Snowy Hills: Highlands with thick layers snow on top.
 * Acid Lake: Doesn't actually have acid, named due to a small pond of green colored Terrain with red dirt forming around them

Exotic

 * Hollow Hills: An erratically generated zone with large spans of hill and giant hollow cavern areas
 * Mushroom Forest: A forest of tall growing mushroom, a great place to start exploiting massive amount of Research Items
 * Exotic Savanna: An expanse of gigantic Ferns growing around. Also, a great place to start exploiting massive amount of Research Items

Radiated

 * Worm Pits: The only surface biome of the radiated planet, indestructible Worm pits spawn all over the planet. If you fall in, you will die, and all of your items will be absorbed by the worm.
