Levolution is a term created to describe the changing battlefields of Battlefield 4. Buildings collapse, cities are submerged in water and vehicles are rendered useless with blockades.
Rather than having timed-out events that happen no matter what players do, gamers will actually have to follow a series of triggers to create these game-changing events. So maps that players spend countless hours traversing can become fresh and new with dynamic events.
But when viewed from afar it's kinda beautiful. Of course war always looks neat when you can't see bodies.
