I returned my Ghosts to Gamespot, got a refund, no argument, and swapped it for Battlefield 4 + Premium Edition for and extra $30.
So glad I did, as BF4 is a far better game, stable no probs, and way more fun.
Seriously, Ghosts is a broken product. From day one broken, and will forever be broken.
IW will not be fixing their product, end of story. You bought it, now they don't have a problem...until you return it.
Go do it now, kick IW in the fu@$ing nuts!
