Biomes
A World consists of several different randomly generated Biomes which will affect your map depending on which one you decide to land in.
Unlandable biomes:
Ocean
Open ocean. Great for fish - not so great for you.
Ice sheet
The surface is covered with sheets of ice which can be kilometers thick. There is no access to soil or rock, so there are no plants. The only animals seen here are migrating to somewhere else - or badly lost.
Landable biomes:
Arid shrub land
A dry region, but not dry enough to become a true desert. Open plains with grasses and bushes give way to scattered groves of trees. Plants are hardy and there is a moderate density of animals.
Temperate forest:
A friendly biome dominated by forests of deciduous trees interspersed with fertile clearings. Many species of animals move around in the trees and on the plains.
Desert
A very dry, hot area which supports little life.
Landable biomes(not implemented):
Tropical rain forest:
A thick, moist jungle. Dense overgrowth and aggressive wildlife make construction and survival difficult.
Tundra:
These mostly-frozen plains bear almost no trees and little vegetation. There are a few small animals interspersed with large herds of migratory grazers and their predators.
Boreal forest:
Northern forests of coniferous trees. Despite the harsh winters, boreal forests sustain a diverse population of small and large animals.
