Disney Interactive announced Thursday that it will be shutting down "Marvel: Avengers Alliance" and "Marvel: Avengers Alliance 2" across all platforms where the games are offered. New purchases or downloads will no longer be accepted as of Thursday, and the game will be unavailable for play as of September 30.

"We greatly appreciate the passion and support of all our players," Disney Interactive wrote in a blog post. "This was a difficult decision, but we plan to focus our efforts on new games for our fans and community. Thank you for playing."

Marvel wrote in another, since-edited, blog post that it is shifting its focus to other online and mobile games, as well as a growing selection of Disney mobile apps.

"We deeply appreciate your enthusiasm and loyal support for Marvel: Avengers Alliance and sincerely hope you will continue to enjoy the large variety of online and mobile play experiences Disney offers, and will bring you soon."

The two games feature different heroes from the Marvel Universe, as the gamer plays as an agent of S.H.I.E.L.D. leading the characters on different story missions against a variety of Marvel Universe villains. The games were offered on the App Store, Google Play, Amazon Appstore, Windows Phone Store and Facebook.

Following the announcement of the shutdown on the Marvel: Avengers Alliance Facebook page, fans flocked to the comment section to voice their displeasure.

"Great game in concept, but ultimately it was killed by the unwillingness of the developers to listen to its fans, and an overreaching money grab," wrote one fan in the comment section.

"Marvel: Avengers Alliance" originally launched on March 1, 2012; shortly before the release of Marvel Studios' original "Avengers" film. "Avengers Alliance" was originally exclusive a Facebook game, before becoming available on iOS and Android platforms. "Marvel: Avengers Alliance 2" was released worldwide as a mobile-only sequel earlier this year, on March 30, 2016.
