The latest Call of Duty: Ghosts Squads trailer reveals what we expect is that new game mode – spotted in a bottom prompt that reads “Play Extinction Online” (0:24 mark, faded on left side of screen). So, there will be a new online mode called “Extinction.”
Looking at the leaked Call of Duty: Ghosts achievements list suggests that the new mode will be four-player co-op mode in the same vein as Zombies:

Note the phrases “using a relic,” “escape with all four players” and combine everything we know with the imagery of the above achievements. That’s either an alien or a monster right? Given the space-based nature of the man-made threat in the Call of Duty: Ghosts campaign, it’s a good guess that the next Call of Duty will have players working together to survive against the extinction of our race against an otherworldy enemy force.

This sounds frikin epic. I liked the survival mode from MW3, but it never really lived up to Zombies from the Treyarch games. Now IW is going all out by bringing both traditional survival mode from MW3 but adding another co-op alien survival mode. I SERIOUSLY want a trailer for this. COME ON IW!!!
