64 Players (on PC), Jets, Co-Op and Prone position:
Battlefield 3 is the true successor to Battlefield 2. Beyond our signature multiplayer, we have also included a full single-player campaign and a co-op campaign – all straight out of the box. As for fan favorite features, how does the return of jets, prone, and 64-player multiplayer (on PC) sound? All this built with our powerful new game engine Frostbite 2, which you'll hear and see a lot of in the months leading up to launch. For the full reveal on Battlefield 3, stay tuned for links to our cover stories hitting the gaming press throughout February, starting with Game Informer right now.
