Frank’s Countermeasures
Without a doubt, Gillian, the in-game assistant was pretty useful. Although she was unable to display her powers, at least she was still able to assist in other ways. She could observe his environments and would lessen Rhode's burden.
Of course. This was only limited to the immediate surroundings. There was no way for her to see or hear a thousand miles.
For Gillian, this was more than enough. She wasn't a human, however, her senses were much better than a human. In this narrow and dark tunnel, she could easily detect the enemy distance, direction, speed and quantity with her ability.
Rhode was unable to do this himself, of course. But his ability to focus was top notch. Although his actions were fast, each movement he made all contained his elaborate planning and preparation.
