Catanzilla
A cooperative variant for Catan by Klaus Teuber, designed by me, J Tags Tarpey.
Objective
Work together to build and connect harbor cities to a city at the center of the island, but you'll have to deal with Catanzilla (a monster that wanders around the island, destroying everything in its path).
Setup
Setup like normal (this includes receiving resources from the second settlement you place on the board).
How to play
Take turns as normal, but after you roll for resources on your turn, you must move Catanzilla before collecting resources.
Moving Catanzilla
Catanzilla moves along the edges of the tiles.
After each resource roll, move Catanzilla one segment towards the nearest tile of the number you rolled (the example is for a roll of six).
If Catanzilla moves over a road, settlement or city, destroy that item and remove it from the board.
If you play a knight, move Catanzilla back to the center of the desert tile.
Special Situations for Moving Catanzilla:
If a seven was rolled, move Catanzilla towards the coast.
If both tiles are equidistant from Catanzilla, you get to decide which path it takes.
If Catanzilla is already bordering the tile that was rolled, move it into the center of that tile. That tile will not produce resources this turn. It will not produce resources until Catanzilla moves off the center of the tile.Â
Trade
On your turn, you may only trade with players that have at least one city or settlement connected via a roadway to one of yours.
In this example, blue and orange may trade with each other.
Victory Points
Keep track of Victory Points as normal (including logest road and largest army), but no one can have more than 5 VP than any other player.
If something happens so that someone has more than five VP than another player, that player must downgrade a city or destroy a settlement to rectify the situation.
How to Win
Each player must build a harbor city that is not immediately adjacent to another player's harbor city.
To win, each of those harbor cities must be connected via a roadway to a city that borders the center tile.
MORE WAYS TO PLAY
Increase the difficulty by increasing the number of segments Catanzilla moves each turn from one to two, or three!
You can also add rules around trading like only allowing one-to-one trades.
