So, way back when I got the Bat Tank. To my surprise, it contained a misprinted torso - a white Batman.
My first thought was, "Cool. Batman in outer space. Of course he'd be white." Or maybe he's part of that crisis thing that DC had.
At any rate, thoughts for the design finally gelled a few weeks ago. I think you can see mostly nnenn and Adrian Florea in it, but the overall shape comes from Ikaruga and Radiant Silvergun, two awesome shmups from Treasure.
