Re-Reckoning saw an exclusive expansion titled Fatesworn.[94] Kaiko were described as enthusiastic about Fatesworn's development, consulting with former staff members about its design.[85] Auseon returned as lead writer and narrative designer, while Kirkhope was brought back to compose new music.[54][94] The expansion was described as being mostly new, though it used "loose ideas that [the team] picked up" from the original development.[85] The team needed to create new editing tools and production pipeline, with these and working with the existing game environment causing production delays with the expansion.[85][95] The expansion was released on December 14, 2021 for PS4, Xbox One and Windows.[94] An arena mode tied to the expansion was released on December 23, unlocking exclusive rewards and challenge fights.[96] The Switch version was delayed from its original 2022 release due to quality concerns,[97] eventually releasing on March 12, 2023.[98]
All versions of Re-Reckoning were given scores equating to "mixed or average" reviews from Metacritic.[99][100][101][102] Jon Ryan of IGN felt that while still a solid game, several of its elements had aged over time and were outdated compared to more recent titles.[103] RPG Site's Adam Vitale called Re-Reckoning "a good introduction to a universe that doesn't have any other entries",[104] while PJ O'Reilly of Nintendo Life felt the game was both lacking in depth and showing its age.[105] John Rairdin of Nintendo World Report called the game " an enthralling, though flawed, adventure that perfectly encapsulates a very specific era in game design history."[106] The initial versions were criticised for technical issues not present in the original and a lack of graphical upgrades,[103][104] while the Switch version was seen as a serviceable port.[105][106]
