If you are looking forward to the release of the new BioShock Infinite game currently being developed by Irrational Games you might be interested in some new footage of the game which has been released in a trailer which has been created for the Tokyo Game Show.
The new BioShock Infinite game will not a direct sequel or prequel to previous BioShock games, but takes place in an earlier period and within an entirely different setting than the original, though the new BioShock Infinite will feature similar gameplay concepts and themes.
The primary setting of BioShock Infinite is a city suspended in the air by giant blimps and balloons, named “Columbia” around which you travel using monorail tracks as seen in the trailer. BioShock Infinite will be released sometime in 2012 on the PC, Xbox 360 and PlayStation 3.
