Following up the 2006 platinum seller Ghost Recon Advanced Warfighter (GRAW), Ubisoft brings the sequel GRAW2, with more of what fans loved about the original with 12 single player missions, 14 multiplayer maps, and a 6 mission coop campaign. You are the Soldier of the Future 2.0. All systems have been upgraded to give you more power and control on the battlefield. Following the failure of the “coup d’etat” in Mexico City Mexican rebels have gathered their remaining forces along the US border. Lead your team of elite Special Forces for the first time on US soil - straddling the border between Juarez, Mexico and El Paso, Texas. The Ghosts have less than 72 hours to stop a nuclear attack.
