Deviations from the comic story

 * The unnamed village of the original story is explicitly identified as Stockbridge in the audio adaptation.
 * Doug and Viv are new additions to the adaptation, the latter's parallel counterpart replacing Maximus Bilious as the commentator at the Colosseum.
 * Grubb attempts to defend himself rather than simply hiding from the android legionnaires. He served in the home guard.
 * When the village is invaded, the Doctor makes mention of the space-time telegraph he gifted to the Brigadier and considers using it to deal with the Iron Legion menace.
 * Prior to opening the Games, Adolphus's choice of leisure is changed from a toy rocket to a video game. He's also explicitly identified as 16-years-old, while his comic counterpart looks a handful of years younger.
 * Morris rather than the Doctor makes the "parrot face" jibe to General Ironicus, threatening him with the bact-gun.
 * Searching through his database of alien species, the Doctor mentions Morax, created for Series 11 in 2018.
 * Vesuvius retains his memory in the original story, revealing Magog's place of power before Morris' demise.
 * The Doctor "supes-up" Morris' bionic arm with his sonic screwdriver, whereas in the original story Morris did it himself, previously serving as a gladiator in both versions. In the adaptation Morris frightens off the overseer. Originally he incapacitated the eponymous overseer with a grate from the air-galley's hull.
 * The Doctor uses everlasting matches rather than a welding torch to relight Vesuvius' flame.
 * Morris is fatally wounded by an overloaded bacterial cartridge of a bact gun, whereas in the original story he is wounded in the explosion of the chariot's engine caused by a corrosively impaired legionnaire. The Doctor purposefully lands in the adaptation, but in the original it was beyond his control.
