Exium#

Exium is one of two resources available in Galactic Empires(in addition to  Credits ) and is needed in order to build or research anything.

Exium can only be produced on some planets and must be extracted through the development of exium mines upon those planets. The higher the exium percentage (max = 30%) on these planets, the more exium that will be extracted per mine.

Unlike the credit cost, there is no way to reduce the exium cost of building/researching.
