Marvel Heroes, Gazillion Entertainment’s free-to-play action-RPG featuring a cast of Marvel’s superheroes (and the occasional villain), is shutting down. A representative from Marvel‘s parent company Disney confirmed the game’s closure.

“We regret to inform our Marvel Heroes fans that we have ended our relationship with Gazillion Entertainment, and that the Marvel Heroes games will be shut down. We would like to sincerely thank the players who joined the Marvel Heroes community, and will provide any further updates as they become available.”

Marvel Heroes was originally released in 2013 on PC. The game was later re-released under the names Marvel Heroes 2015, Marvel Heroes 2016 and Marvel Heroes Omega, the game’s current incarnation. A version of Marvel Heroes Omega was released for PlayStation 4 and Xbox One earlier this year.

Marvel Heroes players knew the game’s developer might be in dire straits when, over the last month, the studio stopped talking about progress on the game. Developer Gazillion missed four of its weekly community updates, plus the game’s Halloween event and upcoming Thor Ragnarok movie tie-in content, something the community expected. Fans also noticed that two community managers seemed to disappear from the forum.

It’s not clear exactly when Marvel Heroes will be closing down.
