Activision and Infinity Ward have released the first trailer pertaining to the single player campaign of Call of Duty: Ghosts.

Things take a turn for the worse when the enemy turns our own weapons against us. In the trailer, seen below, the turmoil that surrounds Call of Duty: Ghosts starts off with our own ODIN Satellite mission system being unleashed against us; opening the USA to a new threat. With the combination of an already destroyed nation and the power of our enemy, the USA quickly becomes home to a new war.

Things to take away from the trailer: the USA has been invaded, the country has been decimated by our own weapons, the new enemy is from the Southern Hemisphere and there is space combat!
