DICE has posted another new detailed update on the official Battlefield Blog
, outlining a feature-set they refer to as Levolution, essentially the systems that drive Battlefield 4's various dynamic environment effects.
Levolution is much bigger and broader than simply destroying something. It’s a wide-ranging concept, a collection of ideas and experiences that make Battlefield truly great. In this blog post, learn how Levolution changes the water from calm to raging storm, how visibility goes from clear skies to dark overcast, and how every move on the Battlefield creates ripple effects that make every match unique.
The blog itself is recommended reading for anyone keen for Battlefield 4, as it covers all manner of the game's dynamic environments from the large set-piece destruction like the falling skyscraper, dynamic weather effects, and flooding streets, and a wide assortment of smalller touches that can be individually exploited by players triggering destruction or light or sound to their advantage on the Battlefield.
An accompanying video shows a bunch of this stuff in action, and you can watch that one below.
Battlefield 4 is due on October 31st 2013 for PC, Xbox 360 and PlayStation 3, with PlayStation 4 and Xbox One versions also in the works.
