Plus a new trailer in French!
"We want to build upon what makes Battlefield 3 great, and one of the areas where Battlefield shines is team play," Thomas said. "The way we’re going about it in Battlefield 4 is to highly encourage team play – but never force it. We want to promote team play by creating great gameplay mechanics such as Field Upgrades, Commander Mode, and a new range of gadgets specifically designed to expand co-operation in the field. We have drastically expanded on the tools and benefits of efficient team play, and as a result we feel Battlefield 4’s multiplayer experience is the deepest, most rewarding, and fun experience in the series."
Thomas then details Field Upgrades, which are chained boosts that can affect a number of gameplay mechanics. Basically, it's a way to give individual rewards for squad based team work.
