South China Sea is an expansion for Great War at Sea shipping this coming week from Avalanche Press. The module contains 10 scenarios for potential battles in the 1920s Far East between the United States and Great Britain. Though such battles never materialized, the two powers were prepared at the time for conflicts over maritime trade. As an expansion, in order to enjoy all the scenarios in South China Sea, you will also need to have Sea of Troubles, Jutland, and Plan Gold.
