Here's an interesting rumour: Battlefield 5 may take place during World War I. That, at least, is what one Swiss retailer thinks, listing the game as a "multiplayer tactical shooter" set during the aforementioned time period. World of Games – the store in question – has since edited the page, but has left in a 26th October release date.
But is it speaking the truth? Well, it's not unusual for retailers to be briefed ahead of a game's announcement, and EA's Blake Jorgensen did suggest eons ago that the sequel would plot a return to a traditional "military-style" Battlefield game. World War I would certainly stand out in a modern military dominated space, but we reckon that the chances of this turning out to be true are low.
