環境改造 is the act of changing the planet classification of a
行星 in order to make it more
habitable for the empire's species. The base technologies requires significant
社會學研究 research to unlock and each terraforming project requires significant investments of
能量幣 and
.
The first time a planet is terraformed, there's a chance of triggering a terraforming event. Terraformed planets can't get colony events.
Terraforming requirements[編輯 | 編輯原始碼]
Terraforming is started via a button in Planet Detail view. The world must be surveyed and within your borders. Only habitable worlds and
barren worlds that have the rare 
環境改造候選 modifier can be terraformed. The expansion planner screen can be used to find these rare candidates.
It is possible to terraform inhabited planets if the empires has the
生態適應 technology. Doing so inflicts a -20%
幸福度 penalty on the planet for the duration of the procedure.

都市星球 worlds are created via
決議s rather than terraforming. They must be inhabited but pops do not suffer a happiness penalty during the process.
The following 
行星修正s are always removed when terraforming a planet:

蒼茫大地

Irradiated

變幻莫測的天氣

鬧事的動物

狂野之風

Second Home
If the planet is being terraformed into either a
Machine or
蜂巢星球 the following modifiers are also removed:

致幻大氣

催情大氣

鬱鬱蔥蔥

自然景觀
If the planet is terraformed into a Machine World, the 
Paradise Made modifier is also removed. Additionally, if there are any
Pops on the planet without the
神經機械,
機械體, or
機械 traits, they're all killed and an
Organic Slurry deposit is added.
When and if terraforming a planet to Hive or Machine World, keep in mind that all planetary features, excluding a few rare ones that give access to rare resources, will always be removed.
