As expected, Treyarch and Activision released the first reveal trailer for Zombies gameplay in Call of Duty: Black Ops 2 today. The trailer gives gamers a glimpse of what to expect in the new Zombies mode. Zombies now have glowing blue eyes, and the entire game itself seems to have an even darker sense to it. The characters that gamers will play as are also shown in the video, but not much information is known about that. Treyarch also briefly reveals the different game modes that will be coming to Zombies, but it isn't very clear exactly what they are.
