As we have communicated in the updates to our backers, all of the core content for the game is developed and in a complete state.
However, there are still bugs and issues pertaining to the online features that are included in the game. These bugs and issueshave a direct affect on enjoyment of the game, so a decision was made to work these issues out before release.Currently, comcept and their partners are working at full capacity to resolve these issuesand fix any remaining bugs.In addition, we have received quite a few requests for additional informationregarding the various platforms that are part of the platform survey we have sent out.We have also only managed to receive around half of the total responses neededfor the survey.Considering the fact that the game’s release has been delayed, we are planning toopen another platform survey once a final release date has been settled upon.We will continue to deliver the most up-to-date info to our backers and fansthrough our forum updates, so please keep an eye out!We appreciate your support and patience regarding this matter, and lookforward to delivering Mighty No. 9 to our backers and fans in the best state possible
The developers are now aiming for a Q1 2016 release.
The game was originally slated for a September 15, 2015 release date, but now there is no solid date for the games release. The delay blamed the bugs on the online features of the game. The core content of the game, however, is stated to be complete in the post. Hopefully, there will be an earlier release date than later.
