Platinum Games have released a ton of concept art showing the design and evolution of the characters in Metal Gear Rising, especially enemy bosses Samuel and Mistral.
Metal Gear Rising concept art
The art is the work of Platinum concept artists Zhao and Kenichirou Yoshimura. According to posts over at the Platinum Rising blog Yoshimura’s involvement came about after seeing initial Rising designs and flipping out at their un-Metal Gear-ness. “I slammed my fist on the director’s table. ‘You cannot put this in a Metal Gear game!’ I told him”, he claims to have said after seeing the early work. Anyway, there’s some great stuff in here and loads of detail.
Thanks Platinum 1, 2, 3.
