Yes, there is a Gunbird 2 remake (!) and it’s coming to PSP in February 2010. PM Studios, the group that brought DJ Max to North America, is publishing Gunbird 2 Remix as a PlayStation Network download.
This version has been updated with hybrid 3D/2D graphics. Otherwise, it’s the Gunbird 2 you know and love. You’ll be able to choose six characters (sorry, no secret succubus in this) and see character specific endings. PM Studios mentions “special two player endings” so it sounds like Gunbird 2 Remix, at the very least, will support ad-hoc play.
PM Studios is also extending their reach into Europe. PAL gamers will be able to get Strikers 1945 Plus and an updated version of DJ Max Fever as PlayStation Network downloads in January 2010. Gunbird 2 Remix will be available in both regions in February 2010.
