The Liberator Chronicles are a series of audio adventures produced by Big Finish Productions, which continue to build on the Blake's 7 universe. These are released as a series of box-sets, each containing three audio stories.
Each story generally has one or two 'lead voices' with another character/voice supporting them. The stories are told through a mix of narration, dialogue delivery and sound effects / music. This 'enhanced audiobook' style first began in Big Finish's Doctor Who The Companion Chronicles range of stories.
The Liberator Chronicles paved the way for Big Finish's range of full cast audio adventures The Classic Audio Adventures which feature all of the original cast (minus Peter Tuddenham) of television Blake's 7.
