This trailer appears to be some sort of painful brainwashing and augmentation process that Raiden is going through. If you ask me, that looks an awful lot like Solidus at the 42 second mark. Which means this video COULD be seen from Raiden’s perspective when he was a child soldier and under the “care” of Solidus. The fact that “Jack the Ripper,” Raiden’s nickname as a child soldier, is repeated several times seems to back this theory up.
Hopefully we’ll find out more when the third and final video is released. Until then, feel free to interpret the trailer below and let us know what you think.
