I'm doing something a little interesting on the Essence front.
Firstly, in my mind, that street sam with a lot of augmentations is pretty heavy. Those floors will not like it, especially false floors. They'll have difficulties dealing with that much weight. I'm only talking in the order of 150KG or so total weight.
The other part is that in my mind, there'd be a lot of bad reactions to someone going to that level. I'd even award Notoriety for being that augmented. Some groups might simply not deal with them at all. Distinctive Style might also work as a way to show they're that augmented.
The other part, that people stop really noticing the character as they're walking. You know when you run towards an elevator and no-ones holds the door for you, someone bumps into you because they didn't see you, doors won't open first time every time. Things like that, it doesn't actively help the character, but those they talk to need to focus on the conversation, the person they're talking to. They need to focus on that person actually being there. They might need to repeat themselves a few times just to get the message across.
I was thinking of starting this in the order of 3.5, 3.0 Essence, where it only picks up to more events the lower it gets. When it gets to the cyberzombie stage, I'd say they have serious issues just being recognised as a person, seen as nothing other than a wall, electronic piece of security.
