An adventure I wrote as a one-shot for Gen Con 2006, and as such might need a bit of adapting for your campaign. Its difficulty level is set for starting characters. This is a heist adventure designed to be very much a one-shot, as the payoff for the run is enough for several runners to retire in wealth. Unless you're using this one as your last run, you'll want to tone down the payoff.
