Sword Art Online Re: Hollow Fragment is a Japanese role-playing game developed by Aquria, released in 2015 for PlayStation 4 and PC. Based on the Sword Art Online light novel franchise, it serves as an expanded Director's Cut edition of Sword Art Online: Hollow Fragment, incorporating several additions absent from the original release. These include an online multiplayer mode, additional boss encounters, and the option to play as a female character. The game draws from the broader SAO universe and carries forward the series' action-oriented RPG structure, with the new content representing a meaningful expansion over its predecessor rather than a straightforward port. The additions collectively make it the most complete version of the Hollow Fragment experience available at the time of its release.
