Black Ops II won't actually be out until November 13, but that's not stopping Activision and Treyarch from putting out a launch trailer a month in advance. Sure, this sort of thing usually comes a week before launch, or day of, but a month early works too.
There's nothing really new in the trailer, as launch trailers tend to be about montaging as many action sequences as possible into a couple minutes.
In Black Ops II, players jump ahead to the year 2025, as an international crisis grips the world, and we learn the hard way that superior technology is worth squat when that tech falls into enemy hands.
Recently, Activision announced a Season Pass DLC system for the upcoming Call of Duty, while Call of Duty ELITE will be completely free. That's all the services offered through ELITE, not the DLC itself. Obviously, you're still going to have to pay for map packs.
