Following the failure of the coup d'¿tat in Mexico City, Mexican rebels have gathered their remaining forces along the US border, and the whole of Mexico is undergoing a full-scale civil war. The Ghosts have fewer than 72 hours to stop a nuclear attack. It's the first time on US soil that you get the chance to lead your team of elite Special Forces - straddling the border between Juarez, Mexico and El Paso, Texas. The Ghosts are the last line of defence and must do what it takes to protect the country. You'll battle enemies in mountain terrains, barren deserts and on your home turf in El Paso. Each environment comes with its own benefits and challenges and thus require new tactical approaches.
