Oddly, I haven't been able to find any discussions on this. I guess most of the implants wouldn't be massively useful, though +4 DT isn't anything to sneeze at in any mode. It seems logical and it would be a nice little money sink. The only remotely relevant discussion I found was this, which seems to indicate it should be possible, at least. :smile: Definitely wouldn't apply to ED-E, probably not to Rex, and maybe not to Lily and Raul. (Maybe Lily and Rex could get the 6 physical implants with a Medicine and/or Science skill check, and/or a consultation with Dr Henry.) I can't think of any physiological difficulties in giving implants to Cass, Veronica, Arcade, or Boone, though. The Endurance limit would apply as normal. Maybe the monocyte breeder would have to be excluded if it caused scripting headaches, but that one's even less relevant for companions than players anyway, unless you're using some kind of mod which prevents their automatic health recovery. Am I missing something super-obvious, or might this work?
