I whipped up THIS little graphic today for a campaign I'm hopping to run in the not so distant future. I thought I'd share.
The basic idea is that the runners are hired to investigate some corp that is marketing an experimental vaccine against goblinization. It should be obvious from the racist overtones who's ultimately behind it, but I'll let you fill in the blanks. You can also decide if the drug does or doesn't work, depending on your campaign. The catch is the drug causes adverse reactions in the mother or horrible birth defects (if given prenatally) and any number of other adverse effects in the child (postnatal).
Have fun.
