The first BioShock 2 trailer finally showed us some gameplay footage (Read: ‘BioShock 2′ Gameplay Footage) and it was a wonderful treat — now comes a 9-minute long video walkthrough from IGN of what’s likely to be the game’s opening sequence and/or demo.

The walkthrough is with BioShock 2 Creative Designer Jordan Thomas, who will offer a little insight into what to expect in the game while showing you in the game itself. You will notice many parts that were featured in the trailer above, but with a much more in-depth look at these parts.

Many people seem to be against this game coming out, but we have to keep in mind that is a game, not a movie. Game’s are built to have sequels if the original finds success, and their sequels tend to be a lot more well-done than the movie follow-ups that we’re so used to. Even if the first game is the best of the best and can not possibly surpass the first, why not travel back to our haunting and beloved Rapture for more adventures? This is why I’m so excited to see what they come up with.

Another reason I’m excited is in regard to the certain damaging elements that were in-question before we saw the first gameplay trailer. The main concern, was that our playing as the first ever Big Daddy meant that you would move deathly slow. This concern was answered with the first trailer and in this walkthrough; you can plainly see the movement is perfectly smooth and acceptable. You’ll also see how you can walk the ocean floor, as well as the ability to switch between the Big Daddy’s drill, awesome new plasmids, and various guns.
