Mighty No. 9 has a new launch date: June 21.

The "spiritual successor" to Mega Man has "gone gold," creator Keiji Inafune said, putting Mighty No. 9 on course to launch for Mac, Linux, PlayStation 3, PlayStation 4, Wii U, Xbox 360 and Xbox One on that date in North America and Asia. It will launch worldwide on those platforms on June 24. Deep Silver is publishing the game on consoles.

The versions for Nintendo 3DS and PlayStation Vita will follow at a later date, Inafune said.

Inafune acknowledged it has been nearly three years since the project was initially and enthusiastically crowdfunded by thousands of Mega Man fans and apologized for the repeated delays to Mighty No. 9's launch.

"This is a project where everyone's passions were combined in order to create something very special, and we are looking forward to delivering the final product to everyone who was involved," Inafune wrote in an update on the game's official site. "There can be no stronger connection between game creators and game fans."

Mighty No. 9 was crowdfunded in September 2013 by more than 67,000 donors giving a combined $4 million. Originally slated for only a Windows PC release, Comcept, the studio Inafune founded after leaving Capcom in 2010, added versions for Mac, Linux, PlayStation 3, Xbox 360, Wii U, PlayStation 4, Xbox One, PlayStation Vita and Nintendo 3DS as stretch goals. The extra platforms, plus a suite of multiplayer features also promised as fundraising stretch goals, were blamed for three delays of an announced shipping date or window.

In January, Inafune announced that Mighty No. 9 was delayed from its then-announced Feb. 9 release date to some time this spring. The Feb. 9 launch date was announced in September 2015, a month after Comcept had formally pushed the game's launch date into 2016 and then promised it wouldn't be delayed again. The original Sept. 18, 2015 launch date was announced by Comcept and Deep Silver in April 2015. Mighty No. 9 was first promised for a Spring 2015 launch.
