It looks like copies of Call of Duty: Ghosts are already out in the wild. Considering the game is due out in a week’s time, this should come as a surprise to no one. What is a bit of a surprise, is the reveal of Extinction Mode, a sort of replacement for the ever popular Zombies mode that challenges you to battle off waves of extra terrestrials.

The confirmation of Extinction mode comes after several screen grabs of the mode made their way around the internet over the weekend. You won’t be battling the alien hordes right away mind you, unlike Zombies – Extinction is unlocked after you’ve completed the first five campaign missions in Ghosts.

Check out a brief trailer and official description after the jump!Read More
