Would a Trauma Damper and Platelet Factories help against the unresisted damage from the various drugs like kamikaze? I would say no but one of my player wants me to post the question.

I would say yes... because they both work inside your body. The damage can't plausibly bypass them if it leaves physical damage of any sort.

Its unresisted, but those don't add to a resistance test, they merely mitigate any damage coming in. So yes, they'd work.

I third that...
