Forget that teaser trailer - EA's finally uncorked "episode 1" of its Battlefield 3 trailer and it's right here for your enjoyment (or, depending on your interests, your edification). Highlights include: crazy realistic lighting, an interesting cover mechanic, and the ability to drag downed squadmates to cover. It's not much, but this hype train is just leaving the station and we're a long ways from its fall 2011 desination.
