The GKNOVA6 website (owned by Activision) has been updated again and it now features ... Zombies! We already knew a few days ago that Black Ops has a zombie mode, but it's now been officially confirmed thanks to the GKNOVA6 website.
The video below is taken from the GKNOVA6 website and it shows multiple monitors displaying different footage. Zombies and humans can be seen running around and taking each other on. The video itself has a lot of hints that the whole Zombie incident takes places in the Soviet Union during the Cold War. Mark Lamia, Treyarch's studio head, has also confirmed to Edge Magazine that the Zombies in Black Ops have "evolved" to something better.
