Here's what this week's newsletter from Cubicle 7 had to say about it:
The last few months have seen the release of Defending the Earth: The UNIT Sourcebook, and the PDF release of The Time Traveller's Companion (with physical copies due Feb/March 2013). We're so pleased to be able to share these with you at last!
Our plans for 2013, the show's 50th anniversary year, centre around a series of sourcebooks celebrating and exploring all of the Doctor's adventures, right from the very beginning. Each book will look at the adventures of an incarnation of the Doctor, starting with The First Doctor.
As well as exploring the Doctor's escapades, the books are jam-packed with details on the allies, aliens, enemies and gadgets he encounters, and advice and ideas on further adventures that your group could get involved with.
