Black Ops 2 Zombies Video Teaser 2 Released by Treyarch

Hot on the heels of their zombie tease last night, Treyarch has once again posted another video on their Facebook page. The video this time is just four-seconds long, but it does have have an audible cue that you won't mistake for anything but the undead.

If you're at work, or alone at home, you might want to lower the volume down a bit before watching it.

I don't know about you, but that blood-curdling sound definitely sounds like a zombie yell, no? 

In addition to the video, Treyarch also posted a new image over on their official Twitter and it states, "The calm has ended – they are beginning to return."

Here's the accompanying image:

Yep, those definitely look like zombie eyes glowing, no? Unless, of course, Treyarch is adding killer headlights as a game mode or killer deers with glowing eyes, then this is yet another tease for zombies.

At the rate things are going, it seems Treyarch is set to unveil an image or video everyday until the big reveal. We'll keep you posted on all the undead happenings, of course.

Excited for zombies in Black Ops 2? What do you want to see different this time around?
