The Battlefield Blog kicks off a new series of articles called "The Road to Battlefield 4" with a first installment called "Dialing Up The Team Play" with an in-depth look at multiplayer support in Battlefield 4, DICE's upcoming military shooter sequel. On the topic, a new trailer from the game shows off the game with a French narration that's all Greek to us. Here's a bit from the diary for those who say they want a levolution:

Levolution is an overarching design concept incorporating a lot of features both big and small, that all affect gameplay in some way. You’ve probably already seen what it can do to skyscrapers but it also includes features like changing weather conditions that affects visibility, car alarms and metal detectors alerting players of enemy presence, or the ability to completely shroud a building in darkness and take out the enemies within using your IRNV scopes. Much more than just massive feats of destruction or pretty graphics, the exciting thing about Levolution is how it affects gameplay. From bringing down a skyscraper to securing a zone from enemy vehicles by raising bollards to block entry, Levolution will let you dynamically shape every game. And like so many other elements in Battlefield 4, Levolution also ties into the team play aspect of the game.
