The D-Day folio series consists of four separate games, each portraying a portion of the Normandy campaign area. Turns represent two to three days each; the games cover the campaign from the initial landing to the breakout. Each game comes with one map covering a portion of the battlefield at 2.5 miles per hex. The playing pieces represent the regiments and special battalions taking part, plus the multitude of fire support available to them.

The series uses the Fire & Movement system rules, with exclusive rules for each folio. The folios can be combined to display the entire American or British Commonwealth sectors, or into a single giant game on the entire campaign.

Utah Beach, a late addition to the invasion, was envisioned as both flank protection for the main landings and a launching pad for the capture of the port at Cherbourg. The Allied player uses airborne drops and amphibious landings to secure a large beachhead, including capture of the city of Carentan. The German player must use the limited forces available to prevent it.
