Imperial Settlers: Why can't we be friends? (Expansion)

Imperial Settlers: Why Can't We Be Friends, the first Empire Pack for Imperial Settlers, includes new common cards for the central deck, new cards for each of the base game's four factions, and two new cards for use in the solo game with some factions. One new effect on the cards is "open production", an ability that allows an opponent to visit your building for the resource produced there while giving you the worker who made that trek. Hope you can put him to use once again!
