The Xbox One version of Mighty No. 9 has received an update, but not from a source people might expect. It turns out Xbox Insiders can acquire a 39.29MB update developed by the Xbox Team. As people may recall, Mighty No. 9 was developed by Comcept with Inti Creates and published by Spike Chunsoft in Japan and Deep Silver everywhere else. (Thanks, MechaGS!)
This Mighty No. 9 update is designed to make the Xbox One version of the game more stable. No changelog has been released explaining exactly what the Xbox Team did. However, initial reports seem to suggest some stages run more smoothly and with less lag than before. A public release date for this patch has also yet to be announced.
Mighty No. 9 is available on the PlayStation 3, PlayStation 4, Nintendo Wii U, Xbox 360, Xbox One, and PC. It is supposed to be coming to the Nintendo 3DS and PlayStation Vita in 2017.
