Triggerheart Exelica was delisted from the Xbox Store on August 31, 2023. On January 27th, 2023, developer Cosmo Machia acquired the IP rights to the game. On July 5th, Cosmo Machia would launch a crowdfunding campaign for a future Nintendo Switch release, which is currently slated for release later in 2023. These factors likely led to the end of publishing terms between them and Microsoft Studios, the publisher of the Xbox 360 version.
