BioShock Infinite is designed in a Columbian setting. Columbia is a levitating city which was established in 1900 by the American government. At first look, it seems as though as it has the ambiance of the city but it is actually a well-armed battleship. Due to the isolation of the city, a civil war was waged. The conflict had lots of factions initially but later two very opposite groups emerged. Those 2 groups are the Founders led by Zachary Hale Comstock and Vox Populi led by Daisy Fitzroy. The Founders' ultimate goal is to keep Columbia exclusive to the Americans while Vox Populi believes otherwise.
The game begins in 1912 with the player controlling a disgraced former agent of the Pinkerton National Detective Agency named Booker DeWitt. He was dismissed for being a drunkard and a gambler - probably the effects of the traumatic events he witnessed in the Battle of Wounded Knee. He is given a mission by mysterious individuals to redeem himself.
The mission is to rescue a young girl kept in Columbia named Elizabeth. Booker is tasked to get Elizabeth from Columbia and return her to New York. In the game, it is Booker’s responsibility to protect Elizabeth during the mission. But Elizabeth is not just a powerless girl. She has special abilities that make her very crucial in the civil war. The Founders want Elizabeth because they believed that the she could restore peace and end conflict in Columbia while Vox Populi would rather have her killed. This factor makes Booker’s mission already difficult - but another obstacle makes things even harder. Booker and Elizabeth are also chased by a giant robotic bird-like creature named Songbird.
In accordance to previous BioShock games, BioShock infinite is a first person shooter with role playing elements attached to it. Booker moves through Columbia with his grappling hook. He also uses Skyline, a series of connected railroads connecting the structures all throughout the city. Booker also uses weapons, vigors and gears found in Columbia. He can only carry 2 weapons at a time and is able to have special abilities with vigors and gears.
Elizabeth will not only be following Booker in the game but will also help him. Though AI controlled, Elizabeth will aid Booker with defeating enemies using her special abilities.
BioShock Infinite seems to be a very promising game. It not only lives up to the previous entries in the BioShock franchise but is at par with the games currently released or coming soon.
