All the Strange, Strange Creatures is aliens. Aliens the Doctor has encountered on his adventures. Aliens he has not yet met. Aliens he hopes to never meet again. This supplement provides the Gamemaster with the details of just some of the alien races that the Doctor has encountered, from Daleks and Cybermen to the Vashta Nerada and the Skovox Blitzer.

As well as providing rules and background for each of the aliens included, this supplement also gets beneath the skin of each of them. What makes them tick? What do they do? How do you use them in your adventures? What sort of stories do they appear in? What else might you do with them? And how do you go about making up your own aliens?
