I also figure the nanites are signal noisy.
The initiating Slaver has to have a way of keeping track of the little monsters while they are doing their thing.
It also has to have two way communication.
So any signal to and from the nanites would have to have the initiating code, and an authentication code.
Our intrepid crew in the game world would have to figure this out, and find a way to exploit it.
Probably with more than a few hilarious results.
(Dancing zombied troops anyone?)
Signal noisy is a relative term. Nanites would use spread-spectrum synchronized pulses for directional broadcasting. Command signals after release are encrypted and encoded.
It’ll be like electroshock therapy to the heart. First you administer the shock, then you take advantage of their confusion as they attempt to reestablish communication to decrypt their codes.
Then you rewrite their programming or shut them down.
