"We are trying to grow the franchise in different ways, always, and to do something new for us, whether it’s a feature like the destruction that was added in Bad Company or the single player that was also added in Bad Company. Since then, it's grown and grown as a franchise. Single player has become a core pillar now, and we're adding coop for the first time. We'll see what happens with that; if people like it, if it's fun, it will probably grow into a core pillar, as well," producer Patrick Liu, speaking to Gamasutra on advancing the series' core pillars.
Battlefield 3 releases at the end of the month for PS3, 360 and PC.
