If you diligently avoided last week's GameTrailers TV due to all the BioShock 2 spoilers, the trailer you see above can help provide you with some water-soaked gameplay -- sans all the direct information. We feel it's safe to tell you that 2K Games gave this clip the title "Siren Alley" because of an area in Rapture of the same name, a place that we never got to see the in the first game. Even if you don't watch the video above, you should take one thing from it: The "worldwide embargo" gets lifted this Thursday and a flood of information on the game is sure to follow. If you're really trying to remain spoiler-free on BioShock 2, now may be a good time to go dark.
