Man, remember the Battlefield 3 single-play story, with the train and the... that rat? There was definitely a rat. And a building collapsed. That's all I got. Battlefield 4 looks much more memorable. I certainly won't forget the guy straddling and punching a dog at 1:36 in this trailer.
Maybe it's a dig at everyone's favourite hound from the upcoming Call of Duty: Ghosts. Maybe it's payback after a game spent being pursued by vicious attack dogs. Maybe it's a metaphor. Whatever the case, the scene is definitely going to stick in my head, long after all the things blowing up and crumbling apart fade.
