[10] In 2023, Aether Studios ran a "Workshop Character Creation Contest" for players hoping to get their creation to be part of the Rivals 2 roster;[11] the contest's winner, an anthropomorphic wrestling insect character named La Reina, was announced in July 2024, to be added in an unspecified future update.

[12] Aether Studios has confirmed that all future post-launch fighters will be added for free, and that they intend to eventually include all non-guest characters from the original game.

[4][18] The game is intended to have improved single-player content compared to Rivals of Aether that aims to allow casual players to transition into more dedicated players, though competitive play is the priority of the designers—they intend to have the game be prominently featured at Evo.

[5] A closed beta testing period for the game was originally planned for 2023,[5] but was pushed back to early 2024.

In November 2023, a Kickstarter campaign was launched, seeking to crowdfund US$200,000 to increase the development team's size and ensure a 2024 release on Windows.
