Set in 1912, BioShock Infinite casts the player as Booker DeWitt, a disgraced former Pinkerton agent offered a way to erase his debts: find Elizabeth, a woman imprisoned since birth in the flying city of Columbia. The story follows their attempt to escape the city while uncovering its secrets.
Combat changes with the surroundings. Interiors bring close-range encounters, while open areas emphasize sniping and ranged fighting against as many as fifteen enemies at once. Players must adapt their weapons and strategies to each situation.
