I had sincerely planned to post this last week but time and ill health makes slaves of us all...except for maybe the good Doctor.
Released in 1986 for the Commodore 64, BBC Micro (?), and Amstrad CPC computer systems, the Mines of Terror has you filling the shoes of the 6th incarnation of the Doctor. The object of this computer game is to stop the Master and his production of Heatonite on the planet Rijar as well as retrieve a set of plans stolen by the Master from the Time Lords, plans to build the TIRU device. A machine that allows one to take pieces of time and 'splice' them together. Heatonite, of course is what fuels the TIRU device.
Unfortunately the Doctor is not allowed even his sonic screwdriver to aid him in the game, just the robot feline, Splinx. At certain points of the game you must open up a programming screen for Splinx to give him simple commands, to access places and hidden items the Doctor cannot reach.
As you will see in the below clip, thanks to Youtube, the Doctor is always in the center of the screen with the background moving in whatever direction he is facing. There is no sound for the clip, which is disappointing as I would like to have heard the theme in Midi format.
