Today, TRG has released a new letter written by Creative Director Lee Cummings. There, he explains the new mechanics of Version 2.2, and shows us a little of the new design of the game. He also mentions his further plans after 2.2, including a new set of levels to introduce the Fifth Doctor and Brigadier Alistair Gordon Lethbridge-Stewart, which wil be dubbed "The hunt for Greyhound One" (a reference to the Brig's codename in UNIT). The letter also comes with a special code. Check it out here: http://www.tinyrebelgames.com/#!letter-from-the-creative-director/c23iw
