Unfold the World
The Sixth World is full of dark alleys, twisted corridors, and hidden locations for nefarious activities. Shadowrunners and 16th century explorers both know the same truth—the difference between death and survival when entering a hazardous area may be a good map.
Sprawl Sites: North America presents eight full-color maps that can be used in a variety of sprawls, making it simple for gamemasters to call up a number of different locations when they need it. From a luxury hotel to a collection of blocks in an urban barrens, from a shopping mall to a trideo studio, the collection includes maps that can be used in many different situations. The maps are double-sided, with a key on one side, making them useful as both a guide for players and a reference for gamemasters. The package also includes a booklet providing details on security and other personnel found in the location, along with plot hooks to help involve these spots in your game.
Sprawl Sites: North America is for use with Shadowrun, Twentieth Anniversary Edition.
