Currently the community is awaiting more information about spacestations.
We have been told that, Jr.Dev Nickmiste, is developing something for them but currently no information has been released. Some speculate that it will tie in with asteroids which Nickmiste has also been fabled to be working on. Some others have said that space stations will actually be faction bases and/or worldgaurds on ships, but there is no proof of this.
EDIT: Feature is on hold. Implementation is currently unknown. -JrDev TheTimelord
