Just as Gamespot, IGN has also posted their Special Ops co-op preview from the GamesCom demo. The mode is broken into different groups of missions, and for the demo we saw one in the Charlie group called Breach and Clear. The mode overall is meant to be a high-intensity but brief segment of gameplay in the vein of something like the mile high club in Call of Duty 4. Regular, hardened, and veteran difficulties are available, and you earn stars by completing a mission on each difficulty setting, with veteran earning you three. These stars are then used to unlock more special ops missions. Click here to read the full preview at IGN.
