Campaigns in Europe (CIE) is a two-player series of games focused on campaign scenarios at the division/corps level. The system uses the same maps as War in Europe (WIE), with updated graphics and a more detailed terrain analysis. The counters have been upgraded and are presented with historical identifications. The game system utilizes a Move/Fight, Fight/Move sequence of play to portray simply doctrinal differences among contending armed forces. It also utilizes headquarters units to project logistics and combat support capabilities.
Case Blue 1942 covers the German offensive to the Caucasus and Stalingrad. It ends at the point where the Soviets launched Operation Uranus, their Stalingrad counteroffensive.
Each game turn (GT) represents around one week in clear weather and two weeks in mud and snow game turns. Each hex represents 20 miles (32.5 km) across. German, Finnish, and Western Allied units are shown mostly as division-sized units, with Soviet and Axis Allied units depicted as corps.
