Happy birthday to Mr Sylvester McCoy from everyone at Big Finish!

Since making his first Big Finish appearance in Doctor Who: The Sirens of Time, Sylvester has appeared in more than fifty Doctor Who Main Range titles – and to celebrate the great man's birthday, we've chosen ten special stories to reduce to just £5 each on both CD and Download for this weekend only!

We start things off with a face-off with future TV Master (or should that be Mistress?) Michelle Gomez in Doctor Who: Valhalla, before matching wits against the Ice Warriors in Doctor Who: Frozen Time, the Dar-Traders in Doctor Who: The Death Collectors and the Cybermen in Doctor Who: Kingdom of Silver.

Then the Doctor takes the Black TARDIS for a spin in a special trilogy of releases; meeting Liv Chenka (Nicola Walker) and Voc Robots in Doctor Who: Robophobia, Nostradamus in Doctor Who: The Doomsday Quatrain and faces an elder god with the help of Sally Morgan (Amy Pemberton) in Doctor Who: House of Blue Fire.

Finally, a trip to a UNIT base reunites the Doctor with reformed companion Dr Elizabeth Klein (Tracey Childs) in Doctor Who: Persuasion. Then with junior science officer Will Arrowsmith (Christian Edwards), the trio take off to battle the Sontarans in Doctor Who: Starlight Robbery and Daleks in Doctor Who: Daleks Among Us.

Each of these brilliant titles are available for £5 apiece on both CD and Download, or together as part of the Sylvester McCoy Birthday Bundle – all 10 releases for just £45 on CD and Download, with free UK postage, and reduced postage for international buyers. Offers must end noon, Monday the 24th of August, so order now!

All the Seventh Doctor's stories for Big Finish, across all ranges, can be found here, while Sylvester's latest trilogy of adventures concludes next month with Doctor Who: Terror of the Sontarans. Check out the trailer below!
