The Big Finish dramas will launch in January 2014 with Fractures by Justin Richards, in which an escape from a Federation pursuit ship leaves the crew of the Liberator licking their wounds. As the dust settles, realisation gradually dawns that the trust and camaraderie that has built up between them is dissolving - and one of the crew is working against the rest.
The audios see the return of Gareth Thomas as Roj Blake, Paul Darrow as Kerr Avon, Michael Keating as Vila Restal, Sally Knyvette as Jenna Stannis, Jan Chappell as Cally, and Brian Croucher as Travis, while Alistair Lock voices the computers Zen and Orac.
The writers for the rest of the season are Andrew Smith, Marc Platt, Peter Anghelides, Mark Wright, and Cavan Scott.
The news follows the release earlier this year of Anghelides' audio drama Warship, which first saw the original surviving Liberator team reunited. David Jackson, who played crew member Olag Gan, died in 2005, while Peter Tuddenham - the voice of Zen and Orac on TV - died two years later.
Producer David Richardson said:
The TV series, created by Terry Nation, ran on BBC1 between 1978 and 1981.
