One of my Mutants & Masterminds players wants to make a hero inspired by Aiden Pierce, the protagonist of the video game Watch Dogs. All was well until we came to the topic of hacking things besides computers—as Pierce does in the game—, like phones, vehicles, and bombs.
I thought such a power might just be normal hacking, but this seems to make everyone with a decent Technology skill much too powerful. It also seems like such an ability should be unique to this character. I've considered some kind of environment control, but that seems lacking in possibilities.
How can this sort of super-hacking ability be simulated?
