There are knights in armor, Aztec warriors, ninjas, samurai and special ops commandos outside. There goes the neighborhood! This trailer by 72andSunny (and director Mark Romanek from Anonymous Content) for Activision's upcoming Call of Duty: Ghosts features assorted masked warriors, most sporting ornate headgear or fearsome face paint. "There are those who wear masks to hide. And those who wear masks to show us what they stand for," the voiceover says. "There are those who wear masks to protect themselves. And there are those who wear masks to protect us all." That's about it. We don't really learn anything about the nature of Ghosts itself. I'm guessing it's one of those games where you bat a blob of light across the screen, but I could be wrong. We'll know for sure when Ghosts debuts at an Xbox event on May 21, with the actual release set for November. Some may yearn for gameplay footage, but I'm enjoying Activision's teaser approach, which initially masks the details. The riotous "Replacer" spots for Black Ops 2: Uprising, by the same agency, generate excitement while giving little way, and I'd wager the ominous tone and impressive visuals of the Ghosts promo will get the faithful stoked for battle. Well played!
