How do you create Hyper Gates?

Posted on Tuesday, February 26, 2019

At the risk of appearing dim - how exactly do you create Hyper Gates in Retribution?  I have all the DLCs apart from the Heroes of Star Control and have tried playing Retribution a couple of times. I've had lots of artifacts but nothing to let me build a HyperGate. Likewise can't see an option to build using a constructor or shipyard. I can see other races have built them but when I open diplomacy they don't have any technologies I don't have so I'm stumped. Help pse !
