- rscadd: "Adds Synthetic Blood Substitute."
other info:
- ~~shell IPCs have white blood (other IPCs keep their black oil
blood)~~ (removed/reverted on request, shells keep black oil blood, no
change here with this PR)
- organics can optionally pick the SBS blood type to get white blood
- this is intended mainly for heavily augmented organics, and you have
to be have at least 8 augmented organs or limbs
- white blood has no mechanical differences (positive or negative)
represented in game, as it is supposed to still just be blood (but with
potentially better characteristics)
- white blood is incompatible with red blood, both ways, including organ
transplantations
