Keep in mind the trailer wasn't exactly going to be true to the PnP. The shape, sure, but not the nitty gritty. Two cool cyborgs were in it. After that, whatever rationale you like may be applied.
Skin weave shrugs off lots of glancing rifle hits. It was pretty much the definition of a minimum-damage hit. Point is, a 5.56 does 5D6 damage. roll 5-10 and it won't come close to penetrating standard skinweave. Roll average damage of 18 or so and only a few points will get through - mostly bad bruising or shallow puncture after Toughness.
They've never really covered how skinweave gets punctured, although that's not my idea of how it would work. More like skin-kevlar. I don't think she had skinweave, though. She's a FCB.
As we both know, Wisdom, there is no flesh face plate for FCBs, unless you count the Gemini. I think she was a Gemini, or whatever CDPR would call a disguised FCB.
I don't think the guy was a FCB. No real reason to think he is as opposed to someone with body plating. He could be, I just don't see any evidence for it.
Edit: watching again, his face just seems much more real than hers. Reflections, I think. Hers is ExoDerm and he's the real thing. Once I grasp a RED dev in my limbs, I'll ask clearly.
Shielding against EMP for Full Conversion Borgs costs 2000 eb and, iirc 2D6 humanity? Pretty cheap compared to FCB prices and invaluable in the field. For regular cyberware it costs...have to look this up...300 eb and 1 HC for a limb. Yeah. I always have it. Chris can vouch for that at least in his campaign.
EMP grenades are 200-400 eb and rare.
Both Techtronica weapons which fry you and your cyberware are also rare, but they do work. at Point Blank range, the 3500 eb rifle version forces you to make a DeathSave. If you -make- it, you are rendered unconscious for 2D6x 30 minutes! Ahah! At farther ranges, it merely forces stun saves galore. Hilarious weapon.
