Galactic Trading Center
Added with the update of 28 June 2012, the Trade Center allows doe a limited amount of in game trading, useful to do something with those excess Artifacts you either cant use, or dont use.
Due to the nature of the Trade Center, prices may not be equal, or even close to the Artifacts current value in the open market, through forum posts or trading groups on Facebook, both of which also deal exclusively in Complex Tech Parts (CTP) or Kurinite (Ku) as exchange currencies, sometimes also in Exotic Matter (EM), but just about never in Credits (Cr).
Currently you may only bid on 2 (two) items at a time, same goes for selling items lots (where a lot is 1 or more of the same artifact). Prices are in Credits (Cr).
