Materialising in outer space, the TARDIS is attacked by a missile fired from the dark side of the moon.

  • The novel includes the UNIT rescue scene of Professor Watkins not included in the original televised transmission.
  • Gregory is shot and killed by Benton during the rescue of Watkins instead of being killed by a Cyberman in the sewers.
  • Vaughn convinces Rutlidge to shoot himself.
  • International Electromatics is renamed International Electromatix. The logo is also changed from a representation of the letters to a lightning bolt insignia and the company has a private commune.
  • Jamie writes”Kilroy was here” in the cell, a phrase popularised by American soldiers during WWII.
  • The language is more explicit than the televised version: Packer calls The Doctor a “bastard.”
  • The Brigadier views the TARDIS dematerialisation at the end of the story, the first time this has happened.
  • There is a third man with Benton and Tracy when they pick up The Doctor and Jamie.
  • Turner is not present in the early aircraft scenes, not appearing until the Brigadier sends him up in the helicopter.
  • Planet 14 is referred to as Planet Sigma Gamma 14.
  • The policeman killed in the sewers is described as “young”: On television, he is middle-aged.
  • There is a second private, Harris, with Turner in the sewers who is injured during the battle. The sergeant with the group is not identified as Walters.
  • Packer strikes Jamie across the face upon recapturing him at IE, causing him to bleed.
  • The Doctor addresses Turner as “young man”, a phrase more likely to come from First Doctorhis first incarnation.
  • The missile base is renamed from Henlow Downs to Henlow Flats. Major Branwell becomes Squadron Leader Bradwell and Sergeant Peters become a flight lieutenant. These are RAF ranks rather than the army ones given on screen ()
  • The Doctor is seen to have a neurister fitted when the signal is turned on, rather than it falling off.
  • The Russian shuttle base is named Nykortny, an in joke referring to Nicholas Courtney.
  • The Doctor seems to take longer to realise the Cybermen can launch the Megatron bomb without the signal
