What is the 3rd episode in doctor who the adventure games called

The episode menu located in the data files of City of the Daleks (but later updated to remove the title names when Blood of the Cybermen was released) listed the episode as T.A.R.D.I.S.

In the June 2010 issue of GamesMaster, it said that one episode would take place entirely in the TARDIS, so this episode is likely that one.
