Facilities are structures which develop your planets. Each level of each building occupies one field of a planet. For a decent overview of what to build in the beginning, look at the Quick Start Guide.

See the Dependency Tree for the requirements to certain buildings.

It is possible to cancel the production of a building. When it is canceled, the resources that had been subtracted from the planet are given back. This can be used as a good method for saving resources. It is possible to save resources from plunder by first starting a production and then cancelling it when the danger passes.

Structures on a Planet or Moon can be also deconstructed by clicking on that structure from within the Facilities section.

Facilities cost Edit

Buildings have a base cost in metal, crystal, and deuterium. The cost of a building depends on its level and the base cost of the specific building.

Facility type	Cost
Metal Mine Solar Plant Deuterium Synthesizer
Crystal Mine
Fusion Reactor
All other Facilities

CalculatorEdit

There is a building calculator available here

Buildings construction timeEdit

The base time taken to construct a level of a building depends on the amount of metal and crystal that level costs. Construction times are reduced by Robotic Factories and Nanite Factories (see this last page for the complete formula).

Where t is the time, expressed in hours.

Note : Real construction time is 1 minute 30 seconds less than the original formula. "t" exprimed in hours, it's necessary to soustract 0,025 hour.
