The secret is out -- Call of Duty Ghosts will have Horde-style cooperative multiplayer mode known as "Extinction." Not to let the leaks spoil Activision's good fun, they've embraced them and have been actively promoting it ever since. Today comes a new trailer of the mode which shows a squad of soldiers investigating a small abandoned town, only to find a giant pile of dead bodies. The cause? Aliens, of course.

Cinematic in nature, the trailer is worth a watch for Ghosts fans to see just what they'll be in store for when the game launches next Tuesday.
