State of Decay

State of Decay was a direct-to-cassette version of the televised story of the same name. It was distinct from both the TV story and the Target print novelisation. With a runtime of a mere 60 minutes, and a more or less in-character reading by Tom Baker, it had a very different format to the other two versions of this story.

It was one of the very few pieces of Doctor Who merchandise that was released on ¼" audio cassette.
