Keiji Inafune sure has been busy lately. In addition to stuff like the Soul Sacrifice games, Kaio: King of Pirates, Yaiba: Ninja Gaiden Z, and the crowd-funded Mighty No. 9, he's also working on a new 2D side-scroller with developer Inti Creates.
Announced at the BitSummit indie games festival in Kyoto, Azure Striker Gunvolt is on the way to the Nintendo 3DS eShop. See Inafune's introduction and a bunch of gameplay and story setup in the announcement trailer below.
Here's the official website. Azure Striker Gunvolt is set to kick into action on the 3DS eShop this summer.
