The subject of this article appeared in Call of Duty: Modern Warfare 2.

The Call of Duty: Modern Warfare 2 Demo was released on August 4, 2010, available for the Xbox Live Marketplace and the PlayStation Network store. The demo features "Cliffhanger" as the only playable level. However, this version of "Cliffhanger" is different from the original mission, with the most notable difference being that the C4 detonator is given to the player when Major Petrov says "four", rather than "five." Additionally, the snowmobiles come in at a different time and place than in the level in the full game.

Another detail not directly related to the gameplay itself is that when viewing the trailer, the trailer itself does not have pixelation when having the Xbox video settings at 720p and higher, whereas the original game had a lower resolution video and therefore caused pixelation.

The loading credits have the copyright year of 2009 even though the demo was released halfway through 2010, possibly showing that it was originally made in 2009 but released at a later date.
