It turns out the return of Gungrave in the form of Gungrave VR isn't just a one-off event. Developer Iggymob's head of development recently spoke to Famitsu magazine, revealing that the team is currently working on Gungrave G.O.R.E., a proper PlayStation 4 sequel.
The developers at Iggymob are building G.O.R.E. in the Unreal Engine, and they're aiming for a higher level of quality and a greater scale more in line with current games. Gungrave VR—which is based on the PlayStation 2 entries—will serve as a prequel to G.O.R.E., which the team hopes will properly "pursue the understanding and expression of the Gungrave setting."
For now it's all about Gungrave VR, which is available to download for PlayStation VR in Japan, with a western release to follow early next year.
