The Witcher Vizima Video Tour

The folks at IGN bring us a new gameplay video for The Witcher described as "Vizima according to Geralt." Here's the full description from the game's official community website:
It's easy to notice that you will see the city from the perspective of the main hero's view this time. Geralt will guide you through few districts, and give a biting comment on approached events and situations. You'll see both rich and prospering parts of the city as well as poor and neglected. Vizima is a real, living it's own life agglomeration with citizens interacting between themselves. Also a citizen that is living in the sewers, making his day by devouring decent tax payers. A walk in the gutter is not probably the best way to spend an evening in the city, but well... you don't pick and choose contracts if you are the witcher.
