The Spec Ops mode in the Call of Duty Modern Warfare 3 will feature a new progressive ranking system, online matchmaking system and leaderboards.

A new Survival Mode was also detailed, taking place on Modern Warfare 3's multiplayer maps. Players will fend off never-ending waves of enemies, including attack dogs, suicide bomber dogs, and eventually kamikaze soldiers."You definitely have to change up your strategy as the enemy changes up," Robert Bowling of Infinity Ward told USA Today "Obviously how you fight the kamikaze dudes is different from how you fight the normal dudes and how you fight a dog is different from a dude and how you fight juggernauts, they are not only big and armored, so they will just brute force come at you. But they each have their own way of being taken out effectively."Modern Warfare 3 will release worldwide on November 8, 2011.
