A new Doctor Who eBook delving into the history of the Cybermen has been launched by the BBC.
The Timelord's infamous foes have already been confirmed to return in the upcoming eighth season of the show with Peter Capaldi taking over the lead role from Matt Smith.
The Doctor Who: Cybermen Monster File offers an interactive history of the cyborgs supported by clips, photos and in-depth information.
A brand new exclusive story written by Joseph Lidster entitled Cybermen: Status Update is also included on the eBook, and is narrated by Nicholas Briggs, the voice of the Cybermen since Doctor Who was rebooted in 2005.
The ebook is being released globally and will be available free to UK licence fee payers until July 31, after which it can be purchased on iTunes, Android stores, the Kindle Fire App and Google Play.
