The upcoming Battlefield 5 is reportedly going to be set in World War I, according to a Swiss retail site. The listing on Wog.ch claims that Battlefield 5, the next entry in the FPS series from developer Dice, will be released on October 26th on PS4, Xbox One and PC, but the most intriguing piece of information is that it will be a tactical shooter set in World War I. Since Battlefield 2 the mainline Battlefield series has focused solely on modern and futuristic military combat, with it never having tackled World War I before. If this retail listing is to be believed, then this could soon be set to change. While publisher EA hasn't officially announced the game yet, this would certainly be a nice change of pace for the military shooter genre. With Call of Duty continuing to take players further into the future, turning back the clocks should help Dice differentiate Battlefield from its biggest rival, with many having called for the genre to return to its old-school roots over the past few years.
