The main character, Premiere, will appear emotionless until she interacts more with the characters in-game. This will be part of the mystery of the game.
Another new feature is the character Argo, an informant within Sword Art Online. She will supply your party with information essential to completing the game. There will also be new bosses: Abyss the Imperial Taurus and Grand Admiral Taurus, along with Summon the Fate Dominator.
The game is slated to be released in Fall 2016 on PlayStation 4 and PlayStation Vita.
