User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-68.44.177.126-20130807180618

"dlc 4 takes place in in ww1 era france. map is built the same as tranzit except instead of a bus it's a tank. there will be a giant that must be fought and the wonder weapon is a staff that can be augmented and enhanced. have no fears of it being bad because they fixed all problems that you may of had with tranzit. oh and original characters are back."

Posted this a while ago on the page with the letters. still don't believe me then watch the origins video till the end.
