The Grey Market screen
At the Gray Market XCOM may sell Alien Artifacts recovered from missions. This can be used when you are in need of funds.
Some artifacts are more useful than others, Weapon Fragments is used in most research; Alien Alloys and Elerium in most production. Damaged UFO components can be sold freely, as they don't hold any value for research and manufacturing. Players shouldn't sell Elerium, Alien Alloys or Weapon Fragments in most cases; as it seems that getting and researching new equipment requires very high amounts of these base resources. Corpses can be used in manufacturing but over-stockpiling them isn't recommended.
