Battlefield is known for its destruction, and this is a big deal in Battlefield V, but also new for the franchise is the ability to fortify your encampments with things like a sandbag wall or by building a stationary weapon. One of the more intriguing new additions for Battlefield V is the Grand Operations mode. Building on Operations from Battlefield 1, Grand Operations are bigger and more involved multiplayer skirmishes that play out across multiple stages and modes--and there are rewards up for grabs. In addition to all the multiplayer updates and changes, DICE remains focused on single-player modes, too. Little is known about the campaign, but we know it'll be playable in co-op (the first time since Battlefield 3), and it will tell stories that "may be unfamiliar to players" instead of the well-known ones from Battlefield 1942. At least one of the War Stories will take place in Norway, with a narrative following a young Norwegian soldier fighting to stay alive during the German occupation. In what sounds like a refreshing, more unique take on war games, Battlefield V will offer War Stories from the perspective of saving your family members as opposed to saving the world.
