Big Finish has released details of a new Third Doctor adventure The Annihilators. This is a 7 part adventure that fits in with series 7. Been since they attempted a story of this length in the 25-30 minute format The Game and Cold Fusion were both 6 episodes in length but this eclipses both.
Out of the 7 episode format only Inferno pulled it off well for me.
Anyway, it is available for pre-order and this little chappy has just ordered his.
