With only one week to go before the launch of Call of Duty: Ghosts on PC and current-generation consoles, Activision has officially revealed a new game mode called “Extinction.” The mode seems to be Infinity Ward’s answer to the popular Zombies mode found in Call of Duty games developed by Treyarch.

Extinction will be a cooperative game mode pitting up to four players against waves of alien creatures.
