Developer Dan Fornace recently revealed the release date of Rivals of Aether: Definitive Edition on September 24 for $29.99 in Switch and PC via Steam. Players with the original Rivals of Aether via steam will be automatically upgraded to the Definitive Edition without any charge.
Game info as presented on the official website:
Twelve original characters plus indie guests Shovel Knight and Ori and Sein battle it out in this pixel-perfect platform fighter. Harness the power of the elements and unravel the mysterious conflicts of the planet Aether in Story Mode, a band with friends to take on shadowy creatures in Abyss Mode, and bring your combat skills online to challenge players across the world.
Brand New Modes
The Definitive Edition of Rivals of Aether includes updates to fan-favorite modes like Abyss, along with a new game mode – Tetherball. It’s a sports battle mode that allows players to use their character skills to compete in a best-of-three beach tetherball game!
Improved Online
The Definitive Edition also features a massive upgrade to the online functionality in Rivals of Aether. The player count is going up from 2 to 4 players max which introduces 2v2 and Free-for-All to Online Play in Rivals of Aether. We are also introducing online support for Abyss Versus, Abyss Endless, and Tetherball.
Unlockable Milestones
The Definitive Edition has a great new system called the Milestone System for unlocking cosmetics. 
We hope you check out Rivals of Aether on September 24th on Switch and Steam. Thank you to our fans so far for being a part of our community, and we welcome the next generation of Rivals players joining for the first time on Switch. We will be looking into bringing the Definitive Edition to Xbox One later in 2021.
