Treyarch has released a trailer teasing what appears to be Call of Duty: Black Ops 2's final DLC pack.

The video, titled 'Origins', reveals four new characters and a glimpse at a giant robot, and features the description, "Every story has a beginning... and an end".

Could Origins be the name of Black Ops 2's next Zombies campaign?

Three DLC packs for Black Ops 2 have launched so far, with another set to launch in the future. Activision has yet to announce any official details about the next pack.
