Story Mode is a difficulty level II workout that tasks the entire body with the need to move. No character in any story has ever made it past chapter I without the ability to command their entire body and make ful use of their resources. Story Mode then helps you get on the road to fulfilling the entire length of your own personal narrative. Add EC and you will also feel the metabolic load pile up a little in between sets.
Extra Credit: 1 minute rest between sets.
