We figured we'd see the official announcement not long after Activision dropped hints .

A new mode has been confirmed for the upcoming Call of Duty: Ghosts ; it's called Extinction and it's a cooperative mode that will support 1-4 players. Recruit buddies!

It has been billed as a "unique blend of survival action, base defense, scavenging and class-leveling," and the new trailer (see it below) displays squads of soldiers attacking alien enemies in a rundown metropolis. There are numerous alien types involved, which means we'll probably need different strategies and methods to dispatch them. This is a nice change of pace for fans of the franchise, as they get something a little different. Aren't we all getting tired of zombies by now?

Call of Duty: Ghosts will arrive on November 5 for the PlayStation 3, Xbox 360 and PC, and it's a launch title for the PlayStation 4 and Xbox One.
