Call of Duty returns to its roots with Call of Duty: WWII - a breathtaking experience that redefines World War II for a new gaming generation. Land in Normandy on D-Day and battle across Europe through iconic locations in history’s most monumental war. Experience classic Call of Duty combat, the bonds of camaraderie, and the unforgiving nature of war against a global power throwing the world into tyranny. Call of Duty: WWII creates the definitive World War II next generation experience across three different game modes: Campaign, Multiplayer, and Co-Operative. Featuring stunning visuals, the Campaign transports players to the European theater as they engage in an all-new Call of Duty story set in iconic World War II battles. Multiplayer marks a return to original, boots-on-the ground Call of Duty gameplay. Authentic weapons and traditional run-and-gun action immerse you in a vast array of World War II-themed locations. The Co-Operative mode unleashes a new and original story in a standalone game experience full of unexpected, adrenaline-pumping moments.
