The first new achievement, for "Resurgence Map Pack 1," has been revealed via xbox.com and added to the site. Presumably there will be a new one for each map pack. All the packs will feature two new maps with a new campaign mission and challenge modes, for the low, low price of 80 MSP each! - 4 packs incoming!"
