Set during the Galactic War, Warship - written by Peter Anghelides and directed by Ken Bentley - is a two-disc special, with the adventure on one disc and a behind-the-scenes documentary on the other.
It brings together Gareth Thomas as Roj Blake, Paul Darrow as Kerr Avon, Michael Keating as Vila Restal, Jan Chappell as Cally, Sally Knyvette as Jenna Stannis, and Jacqueline Pearce as Servalan, with Alistair Lock as Zen and Orac.
Peter Tuddenham, who originally provided the voices of Zen and Orac, died in 2007 and David Jackson, who played crew member Gan in the first two seasons of the TV show, died in 2005.
As an intergalactic war breaks out, old enemies become allies, friends will become separated, and Blake will be forced to leave behind all that matters to him . . .
It can be bought as a CD and download. The tie-in novelisation, expanding on the story's events and developments, will be published next month as planned as an e-book.
