Extinction trailer shows Call of Duty: Ghosts' new horde mode

Call of Duty: Ghosts' new four-player horde mode was officially announced over the weekend, after screenshots of Extinction surfaced online. Now Activision and Infinity Ward have released an official trailer, giving us our first look at the bug hunt in motion.

Extinction should be fairly familiar to fans of Treyarch's Zombies mode, with a few twists: its agile enemies can bear down from unexpected places, and its four unique classes can be leveled up to improve their unique fighting and defending abilities.

Call of Duty: Ghosts will launch on Nov. 5 on PC, PS3, Wii U, and Xbox 360, and at launch on PS4 and Xbox One.
