Union Stockyards: Westward Expansion

From BoardGameGeek:

As large stockyards are established in midwestern and western cities, meat packers respond by building slaughterhouses in these locations, expanding their enormous business empires. In Union Stockyards: Westward Expansion, you will expand westward, developing your strategy by using each city's unique ability. Your workers can visit the Exchange Building to access new actions, and new Year Cards will add more rounds and more events to the game. A Solo Mode is also included, where you compete against 1 to 3 BOTs (out-of-town meat packers). BOTs may also be added to multi-player games to alter player count. -description from the publisher
