The price of a ticket to reach the floating city of Columbia just got a whole lot cheaper. If you're looking to play Irrational Games' latest, BioShock Infinite, the game has been reduced to $20 on the Xbox Games Store. There's no telling whether this is a permanent price reduction or limited-time sale, so if you're interested, you may want to act fast.

BioShock Infinite launched earlier this year and has since issued one DLC pack, the Clash in the Clouds arena combat pack. Another add-on episode, Burial at Sea, is also in the works and takes players down to Andrew Ryan's underwater metropolis Rapture – the setting for the first BioShock game.
