Fronte Russo brings background articles and scenarios covering the Italian Expeditionary Corps in Russia (CSIR) and their battles to the Panzer Grenadier game system. It is not playable by itself, but requires ownership of Eastern Front to play most of the scenarios, and Road to Berlin to play all of them. This is a book supplement complete with a full set of die-cut and mounted counters, much like Sinister Forces and East of Suez.
