Reuniting the Seventh Doctor and Ace actors Sylvester McCoy and Sophie Aldred with Hex actor Philip Olivier, Revenge of the Swarm is a sequel to 1977’s The Invisible Enemy, and guest stars John Leeson reprising the other role he played in the serial that originally introduced K9.
Surprisingly, this is a classic enemy Big Finish has so far steered clear of – so, what’s it all about?
The Doctor thought he had defeated the microscopic Nucleus of the Swarm in his fourth incarnation. He was wrong. It survived within the TARDIS, and now it has brought it back to Titan Base, back to the point of its own creation. It has a plan that spans centuries, a plan which will result in the Nucleus becoming more powerful – and larger – than ever before.
To defeat it, the Doctor, Ace and Hex must confront the Nucleus within its new domain – the computer-world of the Hypernet, the information network crucial to the survival of the human empire. But if the Doctor is to save the day, he has to risk everything and everyone he holds dear…
Here’s the trailer:
Released this month and available from BigFinish.com, Revenge of the Swarm is written by Jonathan Morris.
