Activision released a mysterious new video dedicated to Call of Duty: Black Ops II entitled "Origins": the footage shows four characters in a seemingly setting of World War II, combat blurry sequences that appear to involve huge Mechs and an inscription which informs us that " each story has a beginning and an end ."

It seems something related to an upcoming DLC, maybe a new co-op mode given the four characters. We have to wait for official announcements. in the meantime, here's the video.
