The first episode of Doctor Who: The Adventure Games is now live on the BBC website.
The first episode entitled, 'City of the Daleks' sees the TARDIS materialise in 1960s London to find the human race crushed by the Daleks.
As the Doctor you'll embark on a quest to the home planet of the Daleks to correct time and save Earth's last survivor, your companion Amy Pond.
The Doctor Who game was first revealed back in April.
