Set in the clouds instead of under the sea. "Unlike Rapture, this wasn't a secret, underwater city constructed in silence and hidden from the world. [Columbia] was constructed in broad daylight in the 1900s America as an example of the success of the American experiment. This was like the Apollo project for the 1900s... But as the city floats around, to show the despots and the tyrants the success of our system, something terrible happens. As it turns out, this isn't just a flying World's Fair; Columbia is a Death Star. There's a terrible, terrible international incident, and it turns out Columbia is armed to the teeth." In short, things go bad, the city disappears completely into the clouds, and for a long time, no one hears from the floating fortress. The game's story picks up in 1912, several years after those disastrous events. "You're a character this time. You're not an unknown cipher with no identity like you were in BioShock 1." You even have a name: Booker DeWitt, "a disgraced former Pinkerton agent... a man who prowls the docks when there's trouble... a man who gets things done." Wow. When I saw the title, I dreaded an MMO. Thank God it isn't one.
