The company, which sells the games outside the United Kingdom (where they are free to TV licencees via the BBC) have listed the item on the Steam website, which requires its community to 'greenlight' the item to be made available through the gaming system.
The popular Doctor Who TV show, broadcast in over 50 countries and running for more than 4 decades, arrives in a marvelous 3D adventure game! Based on the escapades of the Eleventh Doctor, this is the 5th game in a five-part series, all with standalone stories and all voiced by the TV actors! Once we get this game approved, we'll release the other four games as well! Using a mix of stealth, exploration, traditional adventure game elements, and of course, epic sci-fi storytelling, this game is a must for Doctor Who and adventure game fans alike!
