The BBC has announced that there will be a free episodic Doctor Who game for the PC and Mac titled 'Doctor Who: The Adventure Games.' It will feature the current 11th Doctor and Amy Pond in four unique adventures. Matt Smith and Karen Gillan will actually voice their characters and the episodes will be written by Phil Ford and James Moran.
Steven Moffat, the show's current headrunner, said, "Children don’t just watch Doctor Who - they join in. They make up games, invent their monsters, create their own stories. Now, there’s something else - now they can be the Doctor in brand new episodes."
The first episode, available for free on the BBC website, will be released in June. More information will follow.
