Master - Cyber Failsafe

‘That gives me a wonderful idea,’ she’d said, shooting a grin and a sideways glance at Alit as she began playing the keys on the console. ‘I hope you like surprises.

It seems that everything old me made in that hospital had a failsafe system. I suppose to stop the patients from wandering off mid-conversion.’

Alit frowned. She didn’t understand a word of what Missy had just said. ‘Fail save?’

‘Like a dog on a chain,’ Missy elaborated. ‘If they got too far from the hospital or, I suppose, the factories, their systems would yank them back. If they didn’t return, the system would malfunction or shut down. In order for the Cybermen to leave Floor 1056 – for Operation Exodus to take place – that system had to be switched off. And predictably – logically – the Cybermats have the same cybernetic systems built into them.’
