Our friends are eagerly looking forward to version 7.0, the author, hoping to return.
You need to meet a mercenary fleet in a random encounter event. They will randomly sell wingmen suitable for the captain module. The captain can only be installed on the wingman because this is a special grid created by the author. It is an additional number, but because there is no color number to distinguish it, it is easy to be confused with the "general grid" (gray).
