In addition to the highly-requested Arcade Mode, Street Fighter V: Arcade Edition contains a bounty of new features, including Extra Battle Mode, Gallery, a redesigned UI, and more! All 28 characters will also be present with a second V-Trigger to change the way each battle is fought.
From the beginning, we promised that you’ll only need to purchase the original Street Fighter V, which we’re sticking to. All the new gameplay-related content – Arcade Mode, Extra Battle Mode, a second V-Trigger, the Gallery, and more – will be available as part of a free in-game update for current players! "
