Confirmed biome types
The following environments have been identified from the reveal trailer and official materials. Because the planet is Earth-sized, there is room for far more biome variety than what has been shown publicly.
Forests and temperate woodlands
Dense green forests with tall trees and thick underbrush appear frequently in the trailer. These look like temperate or mild-climate regions with plenty of vegetation.
Grasslands
Open grassy plains are visible in several shots, with wide sight lines and scattered trees. These areas seem well-suited for ground mount travel.
Deserts
Arid landscapes with sandy terrain and palm-like vegetation. At least one desert region is clearly visible in the trailer footage.
Frozen and snowy regions
Ice-covered terrain and snow-blanketed mountain peaks appear in the trailer. These likely represent high-altitude or polar environments. Survival mechanics probably differ here compared to temperate zones.
Mountain ranges
Sean Murray described the mountains as "real mountains, not videogame mountains, but mountains that are miles high, taller than Everest." The trailer confirms massive mountain formations that tower over the surrounding terrain. Murray also stated that "every mountain can be climbed."
River valleys and canyons
Sean Murray described the planet's geography in vivid terms: "You can see rivers and canyons and continents." The trailer shows deep canyon formations and river systems cutting through varied terrain. One shot shows a dragon diving between narrow canyon walls, giving a sense of the vertical scale.
Oceans and coastlines
Oceans are a full biome category, not just boundaries. The trailer shows coastal areas where land meets water, and underwater sequences with aquatic life and coral formations. Murray described the oceans as "as dark and deep as our own."
Volcanic regions
A volcanic environment is visible in the trailer footage, with what appears to be active lava or geothermal activity.
Biome transitions
The trailer shows continuous movement between biome types without hard boundaries. Forests gradually thin into grasslands; grasslands give way to desert. This suggests procedural blending between biome zones rather than the abrupt cutoffs seen in many open-world games.
Unique resources and creatures
The Steam page describes "unique enemies and valuable resources to discover" within the biomes. Different environments almost certainly contain different material types, creature populations, and environmental hazards. The specifics of which resources appear where have not been detailed.
The trailer shows a variety of creatures across biome types: flying creatures in mountain regions, aquatic life in the oceans, and ground-dwelling fauna in forests and grasslands. Boss-scale creatures also appear, dwarfing the player character in scale. Whether specific bosses are tied to specific biomes is unknown.
