Carcassonne: The Invasion
Tile from Carcassonne: The Invasion by Jeremy Chambers. Carcassonne is designed by Klaus-Jürgen Wrede and published by Hans im Glück.
Created by Jeremy Chambers, Carcassonne: The Invasion is a new fan-produced expansion to the basic Carcassonne game, also included rules for Carcassonne: The Princess and the Dragon.
In this expansion, the Fire Salamander has returned to the lands of Carcassonne. Players who are willing can form an unholy alliance with these pyorphiles by using Smoke Cities. Altogether, 19 smoke city tiles are added to the game. Visually, Smoke Cities are "color-deprived" Carcassonne tiles that come with a twist or two. Here is a quote from the rules (the full set of rules is available on BoardGameGeek here:
Smoke Cities
The smoke cities count the same as standard cities for scoring purposes but they have a twist or two. When a player completes a smoke city it scores as normal, but the player may choose to leave their meeples in the city.
If a completed smoke city is connected to any other city by roads (blocking trees and farmhouses do not matter) the meeples of the smoke city can attack the other city when it is completed and give the smoke city owner the points (under normal majority meeple rules). The smoke city meeples would then return to the hand of their owner.
Dragons can fly over smoke cities, but cannot eat meeples that are in a smoke city. (A dragon and a meeple can be on the same tile if in a smoke city). Fairies cannot enter smoke cities. Towers can capture meeples from within a smoke city.
If you do not complete a smoke city you gain negative points at the end of play (equal to the number of positive points you would have gotten in a traditional city).
Farmers are afraid of what comes out of the smoke cities and will not enter one for any reason. Smoke cities that are 2 tiles do not count for farmers. Smoke Cities larger than 2 tiles count as -1 city for farming purposes.
Here is the tile set for this expansion.
