The plot finds gamers searching for stolen artwork in a Bavarian village, only to stumble upon a ghastly Nazi experiment designed to turn the tide of the war. Zombies are another staple of the franchise, and they return as monstrous Nazi experiments in Call of Duty: WWII. Players can take on classic modes like Domination, Team Deathmatch, and Search and Destroy, or they can complete objectives across several maps in the new, narrative-driven War mode. The Airborne, Armored, Expeditionary, Infantry, and Mountain divisions each offer two loadouts, and perks have been abandoned in favor of a progression system. Multiplayer action remains a huge aspect of the Call of Duty formula, with gamers joining the Axis or Allied powers, splitting into five different divisions, and making use of a new headquarters social space. The action is designed to be realistic, with era-authentic weapons, subtler character movement, and a health bar that can only be replenished with health packs. Gamers control Private Ronald 'Red' Daniels, Private Robert Zussman, their foreign allies, and the rest of their squad as they form bonds and fight their way through famous WWII conflicts like the Invasion of Normandy, the Liberation of Paris, and the Battle of the Bulge. Activision's long-running first-person shooter series returns to familiar territory as players battle through the European theater in Call of Duty: WWII.
