Carbon Key

Carbon Keys are the best X-Lab key in the game. Carbon Keys can be used to buy the extremely powerful commanders C-001 and C-003. C-003 is a more powerful commander than C-001 in every way so it is never recommended to buy C-001.
==How to obtain==
Carbon Keys are one of the hardest items to obtain in game. In order to get Carbon Keys, you or your alliance must rank extremely high in events. If you are not a top alliance, then your only hope is to rank high in one of the player events to hopefully get one.
