The Waters of Mars ended with a brief trailer for the Christmas special and it's safe to say that the Tenth Doctor's swansong is going to be electrifying.
The brief glimpses we saw make it clear that it will be chilling, thrilling stuff and we'll be bringing you the usual exclusive videos, interviews and images over the weeks leading up to it.
Don't forget - you can see an early scene from the next adventure during Children in Need night on BBC One on Friday, 20th November.
In the meantime you can watch the trailer right here, as well the scene where the Doctor first hears the doom-laden prophesy plus Executive Producer Russell T Davies giving a little bit away about the big secret... Just hit the link on the right to see the videos.
