It must have been quite a while since I last checked on how BioShock was shaping up, because the game I had in mind since 2004, and the things I came upon today while looking over an article scanned from the GameInformer magazine... well, let's just say they turned out to be quite different. An "underwater Fallout" was the last thing I would have expected from Irrational, but after seeing that retro-style design and some rusty machines from the submerged city in BioShock, I really can't think of a better couple of words for it. As for the gameplay, it's pretty much the same thing we've been hearing all along, except that now you can find a bit more about it and also about the story, from the scanned article that's been posted on the Penny Arcade forum. I for one would rather keep myself in the dark for the time being, but at least the images (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11) are definitely worth a look!
