From the Game Manual:
Edward Grabowski's D-Day: The Beginning of the End gives you your chance to fight World War II in Western Europe, from the Normandy invasion to the taking of Berlin.
You control either the Allies (Green) or Axis (Gray) forces, starting on June 6, 1944; you have just under one year to defeat the enemy by capturing the opposition's cities and winning military conflicts.
Play takes place at two levels: first, you move your divisions across a map of Western Europe in a turn based game at the campaign level; then when two forces meet, a Micro
Miniatures battle takes place with the result having its affect on the campaign level.
This game gives you the chance to rewrite history, by choosing the course that the war will take.
