Hi all, probably a quite simple question but I'm just starting to get into X-wing, have the starter set and wondering what to buy to expand it.. I have noticed there are rules around that aren't in the main rulebook, obviously on ships that were released after the starter set. Is there anywhere online to get these rules or can you only get them with the appropriate ships? The main one I am interested in is the extra action on the TIE Interceptors, I think it is boost? Also interested in what Ion cannons do.

Thanks for any replies.
