Developer Inti Creates recently announced a new indie title for the Nintendo Switch called Gunvolt Chronicles: Luminous Avenger iX at the BitSummit Vol. 6 game show. The Gunvolt seires' signature arch-rival Copen is set to appear as the protagonist for the game.
Though details are scarce, the developer did state that they're currently hard at work on the title and that more information will be shared this summer. For those unfamiliar with the franchise, Gunvolt originally started out as a Nintendo 3DS eShop title called Azure Striker Gunvolt back in 2014. It was followed by a sequel called Azure Striker Guvolt 2 in 2016.
A short teaser trailer and screenshots for the game can be found below:
