Although the latest addition to the franchise and with the grandest production design, Battlefield 1 is positioned as a prequel to Battlefield 1942, the very first game in the smash-hit online multiplayer shooter franchise. It depicts "the war to end all wars", World War I, a conflict that's far less explored by popular culture. You get to experience the very first tanks, automatic weapons, stick grenades, and dynamite. You also get to experience environments unique to WW1, such as the trenches of western Europe and the deserts of Arabia.
Based on the latest Frostbite Engine by EA-DICE, Battlefield 1 takes advantage of DirectX 12 with asynchronous compute to weave together richly detailed worlds. It is heavily taxing on current-generation hardware, and you're handsomely rewarded for investing more into your graphics setup.
