The Mirror's Edge and Battlefield franchises are related through more
than developer-publisher relations -- they're poised to share digital
DNA. If it is made, a sequel to Mirror's Edge may use Battlefield 3's
Frostbite 2 engine, according to Official PlayStation Magazine, which
writes, "The Frostbite 2 engine will pave the way for Mirror's Edge to
make a free-running return."
We don't know much more about the potential sequel or OPM's "inside
whispers," besides the fact that Mirror's Edge is an "important
franchise" to EA. We may have to wait until EA and DICE stop coddling
Battlefield 3 for confirmation of another game or details about its
engine. For now, dreaming about free-running on Frostbite 2 will have to
tide us over. Mmmm...
