Each Memory in the Campaign Booklet begins with the setup of the Map as shown by a diagram.
IMPORTANT: From Memory 0.2 onwards, place the Compass near the Map and always orient it towards the North that is indicated on the map.
Place the Map tiles, tokens and miniatures listed under the diagram. The diagram shows the size and type of tiles to place: Interior, street, roof, (see below). Each type of tile has several variations. Some tiles include 1+ walls represented by a thick black line.
You can place any tile of a given type, provided that its type, size, wall(s) and orientation match the diagram.
