Planetary features


Outliner top.png
This article has been verified for the current PC version (2.7) of the game.

Planetary features represent notable areas on planets. They determine the number of Districts the planet can support and can provide various bonuses to planets. Megastructures, Ringworlds and Ecumenopolis, Hive and Machine worlds do not have planetary features, being able to support as many districts as the planet size but not able to mine Strategic Resources or receive bonuses from special features.


Deposit featuresEdit

These planetary features determine the number of District and Districts and Strategic Resource buildings the planet can support. Gaia planets are more likely to have features that unlock Strategic Resource buildings or grant a higher number of Districts. If a planet is terraformed the deposit features are changed to new ones that allow the same number of Districts to be built.

Blockers are obstacles that block planetary features. Until a Blocker is cleared the obstructed Planetary Feature cannot be exploited. Each Blocker also reduces the maximum number of Districts on the planet by 1 or more, so they are worth clearing even if the extra possible districts are never built. Blockers can be cleared for a cost in energy and time, if the player has researched the required technology. There are 9 such technologies, one for every normal blocker type, and they are all relatively easy to research.
