UPDATE: Infinity Ward has posted a new image showing a new alien from the new Extinction episode Nightfall:

Infinity Ward has just posted a teaser for what appears to be a new Mike Myers game mode that is being played on Fog MP map (thanks to @LiamFTWinter). Liam suggests that the game mode is Mike Myers due to the same theme song as that mode. Here’s a YouTube link to theme song. The house/lay out of the map also seems to match up with the Fog MP map from the poster.

Infinity Ward has also confirmed the Jan. 28th release date of the new map pack, lining with up the poster that was leaked earlier this week. We’re expecting to hear more on the DLC very soon.

Watch the teaser:

UPDATE: Here’s a comparison image between the Fog MP map and the teaser:
