== Worldbuilding ==
* Combatta has programmed all the medical drones with her personality. She believes wiggling her tentacles is calming for humans.
* The planet the Doctor and Tegan visit has been completely converted, with the Cybermen all remaining dormant until needed. They are not aware of intruders unless fired upon; when firing ceases, they become disinterested again.
* The Doctor tries to hack into the cyber-mainframe.
* To trick Herb and Creasey, the Doctor promises to give them the secret of time travel.
* Marc's cyber-conversion is only internal, leaving his skin unchanged, as part of a new infiltration programme.
* The Doctor decides everyone needs a break, and departs in the TARDIS, leaving Marc, Nyssa, and Tegan on Callanna with some money.
== Notes ==
* This story follows directly on from Warzone.
* At the end of the story, the Doctor leaves Tegan, Nyssa and Marc on Callanna. This is followed up on in the story Madquake.
* This was the Cybermen's final appearance in the Monthly Adventures range.
* When The Doctor and Tegan talk about Adric, The Doctor references to having seen his younger self in Adric. This is a reference to Matthew Waterhouse's statement that he thought The Doctor found Adric annoying due to having seen something of his first incarnation (whom The Fifth Doctor tried to distance himself from) in Adric.

* The Cybermen are of the design identified by ArcHivist Hegelia as "CyberNeomorph". (AUDIO: The Ultimate Cybermen)
