Did Christopher Nolan incept the latest Modern Warfare 2 demo?
It's not often that a publisher offers a new demo a year after a game has been released. Of course, it's also not often that a game has an opportunity to subtly tie itself into a summer blockbuster.
So perhaps it's not that surprising that Activision announces a demo of the Cliffhanger level from Modern Warfare 2, which came out a year ago. Does the description of Cliffhanger remind you of any movies you've seen recently?
One of the most recognized levels in Call of Duty: Modern Warfare 2, Cliffhanger thrusts players into an epic fight of a lifetime amid near-blinding snowstorm conditions high in the frigid mountains of Kazakhstan. One wrong move and it's certain death as players scale a frozen mountainside, battle their way through a raging firefight, and race for survival aboard a snowmobile under heavy enemy fire.
