Terraforming

 is a game mechanic in Edge of Space.

Terraforming is a mechanic in Edge of Space that requires you to complete all of the events in a biome; such as in the protolife biome to destroy all of the jelly nests and zombie nests. Once all of the event areas are "dominated" ,as the game states it, that biome can be considered terraformed ,and can be considered livable for humans. Well that's what my theory on what the game means by terraforming ,and at atleast its better than nothing.
