Is it possible to roll in Star Wars Battlefront (the 2015 version) by using the controller on Xbox?
According to this thread, while strafing, hold the crouch button to roll. They worded it as:
Hold the crouch button while strafing right or left and you'll be rolling in no time. Leia and Han had been able to do it already prior to this update.
However, another person said it's double tap the crouch button while strafing. I also saw this answer on another post.
