Info:
This is the skill of getting along in rough company.
A successful Streetwise roll might let you learn (among other things) where any sort of illegal “action” is; which local cops or bureaucrats can be bought, and for how much; and how to contact the local underworld. Note that you might also be able to get this information by asking a Contact. This skill is a measure of your ability to make new connections as needed.
You may substitute an Influence roll against Streetwise for any reaction roll made in an underworld or “bad neighborhood” situation.
