The game stars big boss, and given the fact that this game has been used for promotional purposes.... Thoughts?
In Rising videos that I've seen Raiden finds boxes, cuts them open and people are inside. His lvl 3 comes from his game at the same time representing the series. His lvl 3 doesn't diminish his chances IMO. I believe that Big Boss was already in but this definitely helps his chances.
Did not know this (I'm not a big Raiden fan so I haven't really kept up on Rising), but that makes me feel better about his chances for sure. And it makes me wonder what his level 3 would be...(Maybe incorporate the original Boss or the Patriot gun, or turn the other characters into ration boxes)
