They say the main plot of new Metal gear will take place some time after MGS 4.
But i don´t get it. Didn´t Raiden quit fighting and live a normal life at the end of MGS 4? And on top of that, how did he actually get back his old cyber-body? He had already got new cyber-body with light skin! Any suggestions?
Here´s the Raiden´s ending in MGS 4
