One of the most notable new additions for the upcoming Star Wars: Battlefront II is its single-player campaign. After the 2015 reboot didn't have one, EA heard the feedback and tasked its new studio, Motive, to create an all-new story starring an Empire soldier named Iden Versio. Now, another detail about the campaign has come to light: its estimated length.

Producer David Robillard told Press-Start that the campaign will clock in at between 5 and 8 hours. Of course, this will depend on how you play, but that's the estimate he's provided as a general idea. "We thought that around 5-7, maybe 8 hours is probably a good amount of time…we wanted to stay very driven towards the Star Wars fantasy that the players are going to experience and not have it be drawn out."
