Call of Duty: World at War’s exec producer has been chatting to MTV.com about planned downloadables. It seems we may be in line for something a little out of the ordinary…

According to Daniel Suarez the development team is already hard at work on several pieces of DLC for release throughout 2009: “We want to do at least - the hope is - potentially two, maybe three packs out before we’re all said and done.” he says.

If that’s not already a promising enough start Suarez then piles on the intrigue: “It’s not going to be what we’ve done traditionally. I’ll leave it a little bit mysterious.”

What could he mean? MTV speculates about an extension to the single-player game rather than, say, the usual multiplayer map-pack offering. That would be most welcome, but we’re wondering if Suarez and his team have got something a tad wackier in mind - possibly more along the lines of the Nazi undead assault that is unlocked at the end of the current campaign.

Whatever the case, we won’t have too long to wait to find out since Suarez is promising to reveal all at the beginning of the new year. Meantime he has quashed any notion that the DLC may bridge the gap between World at War and its immediate predecessor Modern Warfare. Yeah, perhaps that’d be a little bit too off piste, even by the current Nazi zombie slaughtering standards.
