Turning the Tide includes 20 scenarios that are updates to the Advanced Squad Leader system of Squad Leader scenarios from Cross of Iron, Crescendo of Doom, GI: Anvil of Victory, the 100 Series, the 200 Series, and the Rogue 200 scenarios. These updated scenarios have not previously seen print in ASL form, although two have been available for download from the MMP website. They range from the beginning of World War II in Poland through the Russian offensive in the Ukraine across the Dnieper River, following the Battle of Kursk in 1943.

Turning the Tide’s scenarios feature the forces of Poland, Belgium, The Netherlands, Norway, France, Britain, Greece, Russia (and Russian partisans), and the United States all battling Germany. Scenarios take place in both night and day, winter and summer, and involve cavalry, motorcycles, air support, parachutes, and gliders as well as armor clashes and infantry battles. Most take place in the countryside, but there are actions in cities and towns as well as forests and mountains, and some involve seizing bridges over rivers and canals.

The majority of the scenarios can be played with just boards 1-5, and only two require a board that was not part of the original SL-GI system. None of these scenarios use overlays.
