A brand new trailer is now up for Doctor Who: The Dalek Contract, the first half of the epic conclusion to the second series of The Fourth Doctor Adventures.

Starring Tom Baker as the Doctor (seen as such on TV from 1974-1981), Mary Tamm as Romana and John Leeson as K9, Doctor Who: The Dalek Contract sees a less than enthusiastic reunion with Cuthbert, last seen setting off an intergalactic incident between Earth and the Laan. And this time he's got a very familiar group of mutated aliens working with him... but can he rely on them not to betray him?

Featuring David Warner and Toby Hadoke - returning as Cuthbert and his assistant Dorrick respectively - and Nicholas Briggs as the Daleks, the stage is set for a massive battle to decide the fate of the Proxima system. Doctor Who: The Dalek Contract is available for pre-order now, and as part of the Fourth Doctor Adventures Series Two subscription on CD and download.
