Resident Evil: Operation Raccoon City won't be out until March, but the good folks over at Xbox 360 Achievements stumbled upon a list of achievements for an "Echo Six Expansion Pack":

"Having played and previewed the first four missions from Resident Evil: Operation Raccoon City, we thought we'd have a bit of a nosy at the game's achievements, only to find that an additional 20 have been added in our preview code, revealing that there's post-launch DLC on the way offering a campaign for the Umbrella Security Services' rivals, the Spec Ops crew."
