Great concept for a board, I think it can only be played appropriately with fog. It has the great feature of an added bonus between colored guns and assassins, so it's almost worth it to go for those if you can.
As with many games of fog, you kinda have to luck out and hope no one is going for what you are, but at least with this map, there are many directions you can go.
One of my favorites...I love the heavy fog. Makes for a thought provoking game. Do you attack and thin out or play defensively. Don't be predictable or you could be assassinated!!
