BioShock Infinite is a first-person shooter made by Irrational Games, the studio behind the original BioShock (which sold over 4 million units worldwide). Set in 1912, BioShock Infinite introduces an entirely new narrative and gameplay experience that lifts players out of the familiar confines of Rapture and rockets them to Columbia, an immense city in the sky. Former Pinkerton agent Booker DeWitt has been sent to rescue Elizabeth, a young woman imprisoned in Columbia since childhood. Booker develops a relationship with Elizabeth, augmenting his abilities with hers so the pair may escape from a city that is literally falling from the sky. DeWitt must learn to fight foes in high-speed Sky-Line battles, engage in combat both indoors and amongst the clouds, and harness the power of dozens of new weapons and abilities.
