IMPORTANT DISCLAIMER : This website is not an official Frozenbyte website, neither an offical guide, it's a documentation player made, which I hope will help people in their way to make their capital ship !
If you want an official source on this matter (and also a full tutorial): https://wiki.starbasegame.com/index.php/Capital_Ships
A full tutorial might come later on here.
Meanwhile if you rather video sources here is one from the Frozenbyte youtube : https://youtube.com/watch?v=_BQXmwnWsNY&feature=share
All informations here have been taken from different sources (Players asking questions directly to me, or in the capital-ship design channel of the Starbase discord) I will maintain this documentation.
If you intend to make videos using the documentation please at least indicate this document as source, as many people like me just bluntly hate spending 1 hour in a 10 mins video trying to look for the proper information in a 10H video with 1000 sponsors and ads.
