Alpha islands

The Alpha islands are biomes designed to reproduce the look of Minecraft's Alpha phase. It is a pretty rare biome that can only spawn in the middle of the ocean as islands, like the Mirage isles. A snowy variation of this biome now exists, called Alpha islands (winter).

This biome does away with the hyper-saturated green of Minecraft's Alpha days and uses some elements of modern generation to the landscape, but still manages to evoke the nostalgic feeling in those who have experienced that historical era. The islands usually spawn in a circular cluster, making them almost look like a peculiar broken-up atoll. Only blocks and, trees and mobs from that version can appear on the island, adding to the out of time effect.
