The release of Mega Man spiritual successor Mighty No. 9 has been delayed for a third time.

The game was due out in April 2015, then September 2015, then February 2016. It now no longer has a release date.

Creator Keiji Inafune blamed issues related to matchmaking for this latest delay.

“In preparation for the February release of Mighty No. 9 we have been working hard with our partners to resolve any network issues and porting work necessary to publish Mighty No. 9 on the various platforms,” he wrote in an update for Kickstarter backers.

“However, the issues relating to the network modes were more critical than expected, and it has become apparent that we will need to delay the game from its February 9th release date.

“We have been working up until the very last moment to resolve these issues in order to make the February release, but it has become clear that we no longer have enough time to fix the issues and have everything prepared for release.”

The large number of platforms the game supports meant matchmaking solutions took time to implement, said Inafune.

Also, the game’s engine is no longer being updated, so adjustments for matchmaking and online code are being made manually by the dev team themselves.

“Unfortunately, this is all a result of miscalculations on the part of us, the development staff,” wrote Inafune.

“As a result, our fans who have been looking forward to Mighty No. 9 have been forced to wait for over half a year longer than expected, and for that we are sincerely sorry.

“I want to take this chance to apologise personally, and on the behalf of the development staff.

“Because we are constantly working on it in cooperation with all our partners, we want to wait and make sure that everything is confirmed to be ready before giving a new specific release date. But we expect it to realistically be in Spring 2016.

“For this 3rd delay of the game, we have no excuses for disappointing our fans and especially our backers once more. We want to take this chance to express our sincerest apologies to everyone who has looked forward to the release.”

Whenever Mighty No. 9 is released, it will come to a mighty ten platforms: Xbox One and 360; PlayStation 3, 4, and Vita; Wii U; 3DS; and PC, Mac, and Linux.
