The story picks  up 10 years after the events of BioShock. Jack, the unfortunate soul from the first game, is out. This time you play as a totally different character, a Big Daddy that’s searching for a specific Little Sister. It’s a tale that lacks some of the bite-your-tongue chaos and panic of the first and, because Rapture is a familiar place now, some of the mystery. But it makes up for that by being more tightly wound and digestible. While Rapture’s still packed with lunatics, a lot of what you encounter, from the audio logs stuffed under soaked refuse to the hastily scrawled messages on the walls, for the most part directly refer back to the main events of the game. For the sequel, where there are fewer questions about what a splicer is and why the city failed and more about who you are and what you’re doing, it turns out this kind of approach works well, driving the action with a more coherent momentum.
