Owners of Tom Clancy's Ghost Recon Advanced Warfighter 2 will be happy to know there will be a reason to pop in that disc again soon, as Ubisoft will release a new set of co-op and adversarial maps through an Xbox Live Marketplace package titled Co-op Collection. The Co-op Collection will come with nine maps; four of them adversarial exclusive, five others shared with co-op. Most of the maps are based on levels from the original Ghost Recon and Ghost Recon: Island Thunder, but two of the adversarial maps are brand new. New achievements will be included as well, adding a total of 110 points to the game. Ghost Recon Advanced Warfighter 2 Co-op Collection will be released next month.
