Lucasfilm is working on a “Star Wars” virtual reality project that doesn’t have a name, release date or even a specific genre yet, but it does have a subject: Darth Vader.

The company announced a virtual reality project, which will be an addition to the “Star Wars” canon, at the Star Wars Celebration in London this weekend. The story will reveal new aspects of the famous villain’s past, as well as try to push the boundaries of storytelling.

The project is being developed by Lucasfilm’s ILMxLAB, a division that combines VFX house Industrial Light & Magic with Skywalker Sound and the “Star Wars” story group. “Man of Steel” and “Batman Begins” scribe David S. Goyer, who also penned “Call of Duty: Black Ops,” is writing the script, and previewed the project at the big celebration.

“What character is so iconic that we need to know more? [Where] we can’t sleep at night and want to experience things that can’t be experienced in film, or can’t be experienced in a novel,” Goyer said, according to Entertainment Weekly. “And we came up with … this person.”

Lucasfilm also rolled out a teaser for the project via the event’s live stream. Goyer made it clear that they were still very much working out the details; he added that he wasn’t even sure if participants should be called “viewers” or “players.” “You don’t play it. You be it. You’re in it. You’re part of the story,” he said.

“The world I came up with, that I’m pushing, is you are ‘the visitor’ – the visitor in this story that’s happening around you that you may have some effect on,” he added.

Other characters from the “Star Wars” galaxy will also apparently appear in the project. Goyer said it’s still another year or two from being released.
