Syndicate/Nightmare Fuel


 * The Leonardo Device (used by the Syndicate to "enhance" their agents), a giant wheel that holds the subject in a "Vitruvian Man" position (hence the name, presumably) and then rips bits off them to replace with cybernetics.
 * The agent 'recruitment' process, which involves finding a random innocent civilian with the appropriate physique, kidnapping them, implanting a mind-control chip in their brain to suppress their free will, then strapping them into the aforementioned device to receive modifications.
