The new Doctor Who Adventure Game will be released October, 2011 and is called The Gunpowder Plot.

It's the most ambitious Adventure Game to date and stars Matt Smith as the Doctor, Karen Gillan as Amy and for the first time, Arthur Darvill as Rory Williams. This new, dazzlingly epic story gives you the chance to battle aliens in London, 1605. But as well as extra-terrestrial monsters, you'll meet Guy Fawkes and really get a feel for what was happening at this incendiary moment in Britain's history. It's your chance to virtually step back in time, chat to famous figures and participate in one of the most notorious plots the world has ever known.

The Gunpowder Plot also sees the return of two old enemies... more about them soon! Right now we can confirm that this, the fifth Adventure Game, was written by Phil Ford (Doctor Who: The Adventure Games, The Sarah Jane Adventures and co-writer of The Waters of Mars) and produced by Gary Russell. The executive producers are Steven Moffat, Piers Wenger, Beth Willis, Anwen Aspden and Charles Cecil.
