[Update: Video has been added back online.]
Earlier today we saw some new Battlefield 4 screens featuring guns, explosions, birds, and sweaty men. More recently, the above video appeared on NeoGAF. It has all of those things as well as upside-down people and a soulful R&B tune.
The short clip above promises a seventeen minute gameplay video on Battlefield's website but, as of this writing, nothing on Battlefield 4 appears to be up quite yet.
