Are Aliens Set to Invade Call of Duty: Ghosts?

It looks like Call of Duty: Ghosts is going to be visited by some hostile guests of the extraterrestrial variety if new rumours about the game's Extinction Mode are to be believed.

YouTuber DriftOr, who leaked Ghosts' name, has apparently done it again; revealling that Infinity Ward is set to bring aliens to the game as the studio's answer to Treyarch's zombies.

Separately the charlieINTEL Twitter account, which specialises in Call of Duty information and leaks, has also said the game is to feature aliens. 

Finally, the images below have emerged and, if legitimate, would seem to suggest that Ghosts will indeed take an out of this world twist. Call of Duty: Ghosts is set for release on November 5th for PC, PS3, Wii U and Xbox 360. It will follow on November 15th on PS4 (November 29th in Europe), and on November 22nd on Xbox One.
