This is the second set of expansions by Alban Viard for the 2010 Essen Fair.
This is a mini-expansion that is intended to enhance other Age of Steam expansions.
The Robot adds a special delivery location to Age of Steam: The Moon. After all of the starting cities have been connected, a robot factory is built, which will crank out black cubes when it receives deliveries.
The Hexpansion is a set of new city tiles that can be used on many existing boards. It allows players to cover up the existing cities with different coloured ones, adding variety to play.
