A trailer - either a downloadable MP3, or listenable directly through the story page - for May's Doctor Who - Last of the Cybermen is now online:

It's been ten years since the final assault on Telos, the last act of the Great Cyber War. Thanks to the Glittergun, humanity prevailed – and the half-machine Cybermen were utterly obliterated.

Out on the furthest fringes of the galaxy, however, they left their mark – in the form of a giant Cyber-head, hundreds of feet high. A monument? A memorial? A tomb? The Doctor, the Cybermen's most indefatigable adversary, sets out to investigate... but he fails to return to his TARDIS. Leaving the Ship, his two companions – brave Highlander Jamie MacCrimmon, and super-intelligent Zoe Heriot – find a stranger in the Doctor's place. A stranger in a coat of many colours, who insists that he's the Doctor – transposed in time and space with one of his former selves...

But why here? Why now? Has the universe really seen the last of the Cybermen..?

Doctor Who - Last of the Cybermen is out in May, ahead of June's 200th story in the main range, Doctor Who - The Secret History. Both stories can be pre-ordered now on CD or Download, or bought as part of money-saving Subscriptions, which also come with PDF scripts, extended download extras, and four specially commissioned Doctor Who - Subscriber Short Trips!
