Speaking to VideoGamer.com senior producer Noah Heller said that World at War DLC will be "off the beaten path" and confirmed that Treyarch has discussed the possibility of adding new campaign co-op missions.
He said: "We're not announcing anything specific yet but I will say we're going to support this game very aggressively. We're definitely looking at doing things other than traditional DLC. We're definitely looking at supporting it for a long time to come because we're really proud of it. There will be a few surprises... we're going to do a few things off the beaten path."
