The Mexico Map – originally released by the Steam Brothers as part of AoS: Mexico, Spain Portugal – features a new special action called Nationalization, which thematically involves player track being nationalized. This new action adds great interaction among the players.

The China Map – originally released by the Steam Brothers as part of AoS: China South America – features another new special action called Diplomatic Pressure. This new action requires players to pay to connect cities into their network. This, coupled with the tough terrain of China, makes this new Age of Steam expansion an exciting and very challenging map.
