Master Europa is a complete set of rules and charts replacing those in the games of the Europa series. This module provides the player with all the materials needed to make use of the latest research available on the entire Soviet military during the years 1939-1945. Over 6,000 counters provide a complete replacement Soviet military and production structure. These counters will work with the existing GRD products, but avoid the 'gaps' where the new games have not filled in. A special set of rules allows this module to be integrated into either Master Europa modules 101 or 102 without difficulty. - BoardGameGeek
