Azure Striker Gunvolt 2 is still in its concept phase, Comcept and Inti Creates said while providing an update on Mighty No. 9 earlier today. As of now, all that has been publicly revealed from the game is the piece of concept art above.
The first Azure Striker Gunvolt was released in August 2014 in Japan and North America. It went on to sell 90,000 units via the Nintendo eShop on 3DS and is currently being prepared for release in Europe, although a European release date hasn’t been finalized yet.
Alongside Gunvolt 2, Inti Creates are also working on a sequel to Gal Gun.
