The brand new trailer for Doctor Who - The War Doctor Series 3: Agents of Chaos is now online, and can be heard on the story's page or by clicking below:

The Time War between Daleks and Time Lords rages across the history of the cosmos. Nowhere is safe. Worlds are ravaged by battles beyond their understanding, but certain other races hunger to fight in the ultimate conflict.

When Earth comes under threat, the War Doctor is drawn into Ollistra’s schemes once again. But the wily Time Lord Cardinal has not foreseen every move. The Dalek Time Strategist has its own game-pieces in play, and when volatile forces with their own agenda join the fray, no-one can predict how the war might turn…

Starring John Hurt and Jacqueline Pearce, Doctor Who - The War Doctor Series 3: Agents of Chaos is released in September, and can be pre-ordered right now for £20 on Download or CD (all CD purchases unlocking a download for instant access). These prices, exclusive to Big Finish, are held until the title's general release at the end of November, so there's never been a better time to place an order!

The entire Time War saga can be bought as a special bundle, gathering together all four War Doctor sets as well as 2017's The Eighth Doctor - The Time War release starring Paul McGann...
