How does this one work? Do I assign it to an existing facility/station and that is transformed into the Command Center? If this is correct, for facilities, it must be a 7x7, if memory serves, but what kind of stations can it be assigned to?
You get command centre DCs when your faction meets the additional active member requirements. Though I have heard a few factions having problems receiving theirs, if this is the case contact an admin via support tickets and they can review to see if you qualify for the additional DC. You would then build it the same as any other facility.
