Welcome to Columbia, the 3rd city in the series. The underwater city of Rapture has been lost to the sea and now it’s time for the next chapter. As in the previous games, the story is told through an interactive map that you can move around. However, this time around, you’ll be following a character named Booker DeWitt, a private eye with a military past. His goal is to wipe his debts with the only skill he’s good at – finding people. But there are many more people to meet and help, and not just in Columbia. The world is full of unique characters and locations. And this game is different from the previous ones.
