Call of Duty: Ghosts co-op game mode outed by leaked achievements - report

Call of Duty: Ghosts may be getting a horde-like cooperative game mode according to this report. The mode is allegedly called Extinction and is probably similar to Treyarch's zombie mode.

Beware of some story spoilers in those achievements

A list of secret achievements for the upcoming shooter appeared on Exophase. The list shows achievements like "Complete all Extinction challenges and escape", "Escape with all four players" and "Escape 1st time," which suggest some sort of survival co-op mode where up to four players fight, well, something.

The eagle-eyed dudes at MP1st have spotted the game mode on the title screen in the recent Squads trailer.

We have no idea if you'll be fighting zombies, aliens or rogue soldiers. We will however find out soon enough as the game launches on PC, PS3, Wii U and Xbox 360 on November 5.
