One of the writers on Metal Gear Rising: Revengeance sheds some light on the story DLC for the game.
Etsu Tamari from the writing team behind Revengeance recently spoke with Polygon about a pair of DLC packs that are soon to be added to the title. Each of them is to serve as a small prequel that will help set the stage and explore the past behind the characters.
We don’t directly explain why Sam works with Desperado in the main story. So that content goes a little bit more into detail on it. The Blade Wolf sub-story depicts a mission it’s running with Mistral before the encounter with Raiden. Both of them serve as prequels to their roles in the main game.
We also get to find out more about the relationship between Raiden and Blade Wolf.
I told people that a cyborg needs a canine partner, and I stood really firm on that. I had trouble figuring out what sort of position it would take in the game, and eventually I came up with the idea that Raiden would take over the ‘teacher’ role for Blade Wolf, the way that Snake was his mentor in MGS2.
