Multiplayer will be presented in this game.
After being exhibited by Cygames at the Gran Brue Fes event though with a very low video resolution, they now provide deeper gameplay details. One of them is a multiplayer feature that will be present in it.
Speaking with Dengeki PlayStation magazine (via Ryokutya2089), Directed by Granblue Fantasy Project Re: Link, Fukuhara Tetsuya explains that they will add multiplayer feature. You can play with your three friends in a co-op while playing it. On the other hand, if you play the game in single player, then you will be assisted by three AIs during combat.
Fukuhara also added that some parts other than the game graphics are almost done, so it is likely that they will soon be completed. Unfortunately for the graphics, they still can not provide quality standards. Therefore, Cygames left their art section, Cydesignation with Platinum Games to work together to determine it.
Granblue Fantasy Project Re: Links will be released next year for the PlayStation 4 and PlayStation VR, no announcements have been made about the English version or the exact season / release date.
