It looks like Doctor Who fans will soon be able to step into the TARDIS in a free-to-play MMO. BBC Worldwide announced today that it has partnered with game developer Three Rings to create Doctor Who: Worlds in Time, a multiplayer online game that is expected to launch later this year.

According to the announcement, players will help the mysterious Time Lord defend civilized culture against infamous Doctor Who enemies. "Our goal with 'Worlds in Time' is to capture the imaginative spirit and depth of the series, whilst being fun and easy to play for all ages," said Three Rings CEO Daniel James.

More information will likely be released at the Game Developer's Conference next week. Are you a Doctor Who fan? Would you play an MMO based on the series?
