Call of Duty: WWII focuses on the actions of a 12-man squad of the American 1st Infantry Division from 1944 to 1945 in the European theater of conflict, at a time when the Allied forces were starting to gather strength on their march into Germany. The campaign will cover fighting in occupied France and Belgium, and across the Rhine river valley into the heart of Germany. Some of the iconic historical battles covered in the campaign will be the Invasion of Normandy (D-Day), Liberation of Paris, Battle of Aachen, Battle of Hürtgen Forest and Battle of the Bulge. Although the story is primarily set in 1944 and 1945, some parts of it will "touch on" events that happened from 1940 to 1944 to "help set the stage for the narrative and establish the characters."
In the single-player campaign, players primarily play as two soldiers of the 16th Infantry Regiment: Private Ronald "Red" Daniels and his best friend, Jewish American, Private First Class Robert Zussman. Additional playable characters include Rousseau, a female Maquis leader of the French Forces of the Interior, and Major Arthur Crowley, a British Special Operations Executive officer. Daniels' and Zussman's platoon mates include Technical Sergeant William Pierson, and platoon leader, 1st Lieutenant Joseph Turner. Pittsburgh Steelers running back Le'Veon Bell and offensive tackle Alejandro Villanueva are set to make a cameo appearance in the game.
