The Armageddon Storm will rage once again, in the final two installments of the Liberator Chronicles...

Available from April 2016, Blake's 7: The Liberator Chronicles Volume 12 is the latest and final entry in Big Finish's long-running collection of audio box-sets based on the legendary Terry Nation's science-fiction series.

Already announced is the set's first story Corners of the Mind by Andy Lane, featuring the return of Avon (Paul Darrow) and Cally (Jan Chappell). But now we turn our attention to the gripping series finale, where the fate of an old ally is revealed, and a terrible weapon is finally unleashed upon the Galaxy – The Armageddon Storm.

'With the Liberator Chronicles reaching their conclusion,' says producer Cavan Scott, 'it was time to wrap up some of the recent storylines including the ongoing threat of the Armageddon Storm - from the award-winning Liberator Chronicles Volume 3 – and the fate of Vila’s father, as played by the legendary David Warner. Guy Adams has crafted a two-parter that is quite literally Earth-shattering.'

The final two stories Capital and Punishment by Guy Adams will see the return of Tarrant (Steven Pacey) and Vila (Michael Keating) – with each character taking a starring role in each part of the story. David Warner also returns as Tavac - Vila's estranged father – whose fate could lead to the destruction of the entire Earth...

Capital by Guy Adams

The Armageddon Storm. A weapon so dreadful that it can lay waste to entire planets. A weapon that Avon has used to hold the Federation to account.

A voice from the past brings news of its redeployment… and the fate of Roj Blake. Del Tarrant is sent to Earth to recover both - but will he survive?

Punishment by Guy Adams

It’s the end of the world and Vila’s father has returned. He isn’t sure what is worse.

With the crew of Liberator arrested and Tarrant dead, can Vila rescue the man he hates and save the day? A coward turned hero… with the fate of planet Earth hanging in the balance.
