The first official trailer for Treyarch's First Person Shooter Call of Duty: Black Ops has been officially unveiled on CallOfDuty.com and Youtube.com following a TV-Spot during the NBA Play-off finals. Black Ops became the highest selling title in the US, UK and EU upon it's release, and so it's no surprise that a sequel has been eagerly anticipated by fans for some time.
For now imaginatively titled 'Call Of Duty: Black Ops 2', the action is set in the early to mid 21st Century rather than during the Cold War. At the very least Los Angeles appears to be a location within the single player campaign, though the stated setting of a '21st Century Cold War' certainly implies that it'll be going a little further afield than West-Coast USA.
CoD: Black Ops 2 is due for release on the 13th November 2012, in what's looking set to be a packed November release schedule also including Halo 4. The game will be released on PC, XBox 360 and PS3. Additional screenshots can be found at AllGamesBeta.com, with more official content due to be released soon on the official site.
