XCOM: Enemy Unknown UFO Video Walkthrough

GameTrailers is offering 19-minute long mission walkthrough of a mission from the upcoming XCOM: Enemy Unknown, a "reimagining" of the original X-COM: UFO Defense, developed by Firaxis, that also provides lead designer Jake Solomon and producer Garth DeAngelis to comment on what's happening.

From what I can see, and as paradoxical as it might sound, this video walkthrough seems to do a much better job at showcasing the game than the actual demo available on Steam.
