The Complex Hub is the docking module for a complex. It is created when the first two factories in a complex are linked with a Complex Construction Kit and can be placed anywhere within 25km of both factories. It is connected by tubes to every other factory in the complex and with 20 docking ports it handles the freighters and customers for every station in the complex.

Any two factories within 25km of each other may be joined to form a complex.
Any factory within 25km of the resulting Hub can be joined to that complex.
Two complexes can be joined together, in such a case, the first Hub to be selected will remain and the second will be demolished.
