In Empress of Mars, the Twelfth Doctor, Nardole and Bill travel to Mars, after NASA discover a message reading ‘God Save The Queen’ under the ice on the surface of the red planet. Upon their landing, they encounter Victorian soldiers, who have arrived to try to conquer the native home of the Ice Warriors. As the long dormant Martian hive begins to awaken, the Doctor must decide which side he is on – that of Queen Victoria's invading soldiers, or the Ice Warriors, led by Empress Iraxxa, and her loyal subject, Friday. The box includes two metal miniatures: The Empress Iraxxa and Friday, and six Exterminate! game cards.
