from the introduction:
This adventure is designed for 4 novice player characters. 4 pre rolled characters are provided at the end of the adventure.
It is placed in the Wild West in Texas around the year 1881. It is a pulp adventure and doesn’t try to simulate realism. The village of Privilegio is totally fictitious.
The characters impress a saloon owner after a bar-brawl (!) and are hired for a simple delivery job, but all is not as it seems.
There a version of this scenario for David Bezio's Wild West rpg Shotguns -n- Saddles, see the entry for The Gatling Decision (Shotguns -n- Saddles edition).
