Producer Jonathan S Powell said: "Zygon Century is back - and the invasion's gone international! After the success of Infiltration, Jonathan Barnes and I were keen to push ourselves further and show our band of Zygons on the offensive. In these three exciting new episodes, we'll take you across the twentieth century, from Russia to Dublin to Death Valley, and reveal more of the Black Cadre's simmering masterplan.
"I'm immensely proud of Zygon Century - it's Doctor Who but it's also proper character drama, and goes places the main series can't. There are many more stories still to be told, and we hope you enjoy these next three."
Script editor and writer Jonathan Barnes added: "I was very keen to come back to our three main characters for the second box set. So we have Herbert Scott, the occult investigator, Vorvoren, the most sympathetic Zygon in the entire series, and Agent Caldwell.
"Not all of these people will survive to the end of the series, and there's going to be many unexpected developments in their stories going forwards. One of the great advantages of writing a Doctor Who spin-off is that we don't have the Doctor for great swathes of these stories, so we have protagonists whose destiny is unclear. That's exciting to work with."
