They must have a lot of free time over at Kojima Productions. I mean, it's not like they are busy working on new Metal Gear games or anything!
A few hours ago, Hideo Kojima tweeted this picture of former Metal Gear Rising producer Yuji Korekado wearing a very flimsy Raiden mask. It looks like something cut off the back of a cereal box and held in place with those elastic mask strings that always break after a single use.
But perhaps this will be our pre-order / special edition bonus gift! A paper Raiden mask is totally worth an extra $20-30, right?
