Guilty Gear 20th Anniversary Pack was released for the series' 20th anniversary and brings two Arc System Works 2D fighting games to Nintendo Switch: the original Guilty Gear from 1998 and Guilty Gear XX Accent Core Plus R from 2012.
The original Guilty Gear introduced the series' hard rock soundtrack, distinctive characters and anime-style story. Guilty Gear XX Accent Core Plus R is the final version of the XX series and includes systems such as the universal overhead Dust attack and the Roman Cancel, which lets players cancel many kinds of actions. Both games support local play for 1-2 players.
The European Day One Edition includes a personal letter from series creator Daisuke Ishiwatari and an art book of his previously unreleased artwork.
