The Zygons have come to claim the Earth, and this time they’re playing the long game. For the Black Cadre have a plan, a plan that will take exactly one hundred years to come to fruition. Prepare yourselves… the Zygon Century has begun! 

The Zygons – first seen in 1975 Doctor Who TV story Terror of the Zygons – are shape-shifting aliens who’ve tried on several occasions to invade Earth by stealing the identities of captive humans. And sometimes, their infiltrations have been more successful than we know… 

Zygon Century, a new range of audio dramas from Big Finish Productions, tells the story of their latest scheme – one that sees them take residence among the human race over a period of a hundred years. 

The secrets of this invasion will be revealed as Zygon Century progresses, though it is primarily an anthology series, with each episode set in a different year over the course of the alien incursion and telling its own complete story. 

The first Zygon Century box set is due for release in January 2025 and includes a turn of the century occult horror, a Cornish folk tale like no other, and an Ian Fleming-inspired action adventure. 

The Worlds of Doctor Who – Zygon Century: Infiltration is now available to pre-order for just £24.99 (collector’s edition CD box set + download) or £19.99 (download only), exclusively here. 

The three stories in the box set are: 

1901: The Unknowing Mirror by Jonathan Barnes
1935: The Miracle of Pendour Cove by Lauren Mooney and Stewart Pringle 
1957: Double Agent by Trevor Baxendale 

Producer Jonathan S Powell explained: “Zygon Century is a hugely exciting sandbox to play in. The Zygons are such endlessly fascinating creations: shape-changers, unusually vulnerable to bullets and, despite their unnatural appearance, capable of the same humanity as we are. Which means there are so many wonderful stories to tell. 

“As an anthology series, each writer-led episode has its own unique genre, style and story, tackling a different year of our century-long Zygon invasion. But just what are the Zygons planning for humanity that will take them 100 years?” 

The Worlds of Doctor Who – Zygon Century: Infiltration is now available to pre-order for just £24.99 (collector’s edition CD box set + download) or £19.99 (download only), exclusively here. 

All the above prices include the special pre-order discount and are subject to change after general release.
