Enough people have "liked" EA's Battlefield 3 on Facebook that a new video has been unlocked, and this time it's actually a commentary track to the 12 minutes of gameplay revealed back at GDC. Executive producer Patrick Bach shares all kinds of insights and secrets on the track, from the fact that attack plan map is actually just a placeholder to the return of a familiar series star.

A lot of the commentary is pretty promotional (yes, Patrick, we know we're seeing lots of effects and that they're courtesy of that amazing Frostbite 2 engine), but there are some good bits in there and, if nothing else, it'll give you an excuse to watch that gameplay video again. You can see a YouTube version of the footage with commentary after the break.
