Mighty No 9 3DS is still MIA, but you'll get to play as Beck anyway.
Following the success of Blaster Master Zero, Inti Creates is doing the Switch/3DS multiplatform approach with a sequel to a 2014 eShop title.
This week's edition of Famitsu magazine detailed Mighty Gunvolt Burst, a follow-up to the retro-inspired Mighty Gunvolt. Both Gunvolt and Beck from lost 3DS title Mighty No 9 will return as playable characters, and the game will feature character growth elements and a bonus point system for close-up ("Burst") enemy kills.
Inti Creates announced last week that they would have two titles to show at the upcoming BitSummit show in Japan, and that to date the Switch version of Blaster Master Zero had sold >80,000 copies.
