Blimey. Where do we start? A brand new Eighth Doctor box-set? A new trailer for the Tenth Doctor and Donna? Romana, Leela and Ace joining forces? River Song meeting two previous incarnations of her husband? Bernice Summerfield meeting an alternative version of her best friend; and the Master! It's been one of the biggest weeks ever for Doctor Who reveals; let's dive straight in!

Doctor Who: Doom Coalition 2 is available now! Continuing on from the events of the gripping first volume, the new set once again pits the Eighth Doctor (Paul McGann), Liv Chenka (Nicola Walker) and Helen Sinclair (Hattie Morahan) against the might of the Eleven (Mark Bonnar); an insane Time Lord whose previous incarnations still exist within his head.

But an encounter with a group of invading Voord places the TARDIS on the trail of a new threat against reality, concealed within the Time Vortex. And this may just be the start of the Doctor's worries; because River Song (Alex Kingston) needs the Doctor’s help on a distant planet.

Watch the video trailer below:

Doctor Who: Doom Coalition 2 is available to buy and download today for just £20 on both CD and to download.

All three Tenth Doctor releases will be available together as part of Doctor Who: The Tenth Doctor Adventures Volume 1 Limited Edition. Limited to just 5,000 copies and available exclusively from the Big Finish website, this lavish book-sized box-set includes gorgeous artwork, photography and articles.

It's not just the New Series stars who are having all the fun though.

While her fellow companions are busy saving our Universe, Bernice Summerfield (Lisa Bowerman) will be heading to a new one entirely! Doctor Who - The New Adventures of Bernice Summerfield Volume 3: The Unbound Universe will see the return of David Warner as the Unbound Doctor, reprising the role he originally played in Doctor Who Unbound: Sympathy for the Devil and Doctor Who Unbound: Masters of War.

This alternative Doctor will recruit Benny for a desperate mission to his home universe – where they'll encounter the Kareem, the Blanks, Unicorns, the Sisters of Saint Beedlix and Sam Kisgart as the Master! You can pre-order this August 2016 box-set today for just £20 on both CD and to download.

While the Unbound Master is waging his scheme in other dimensions, Alex Macqueen's version of the Doctor's nemesis is up to his own evil plots at home.
