Bioshock - Walkthrough Videos

The official Bioshock blog at IGN has two "walkthrough" videos on offer - here's their description:

Rapture is a huge underwater city, and we have seen only brief glimpses at a few corridors and hallways so far, in screenshots and trailers. Currently, we know that Rapture includes seven “decks,” with multiple levels and many different environments spanning each deck.

Fans have been clamoring for a more in-depth look inside Rapture, rather than single screenshots or gameplay videos that often center around only one or two rooms. And while we don’t want to spoil the fun of exploring the city during the game, Irrational has come up with walkthrough videos of two of the first areas in BioShock.
