The trailer and Xbox 360 achievements list for BioShock Infinite were posted online ahead of the games' March 26 release date.

Last week, Irrational Games launched a new BioShock Infinite gameplay trailer focused on the shooter's gorgeous setting, the floating city of Columbia.

The latest trailer for the game is called "City in the Sky" for good reason as it features the floating city of Columbia which will serve as the primary setting for the upcoming game.

BioShock Infinite is the third game in the BioShock franchise. Game developer Irrational released the acclaimed first person shooter BioShock in 2007 and the sequel BioShock 2 was developed in 2010 by 2K Games. This means that the third game in the series will be the original developer's first chance at a sequel.

Some gamers may be wary to jump into the third game in the series but new comers are welcome as the storyline will be different from the previous two titles.

The website for the game gives a description of the game that states: "The year is 1912 and Booker DeWitt is headed to the city of Columbia. A technological marvel amongst the clouds, Columbia holds a dark secret, and with it, a mysterious girl. Upon arrival, Booker discovers that rescuing the imprisoned girl will be more difficult than he could have imagined."

The latest trailer also contains a scene that has many players curious as there appears to be a figure that resembles George Washington about to unleash a rampage with a mini gun, according to GameSpy.

Fans of the series can also take a peek at the achievements and trophies list provided by ComputerandVideoGames.com.

Many of the achievements revolve around killing a certain amount of enemies with a certain weapons that have interesting names.

There are also nine secret achievements that have yet to be revealed.

BioShock Infinite is slated for release worldwide on March 26th, 2013. The game will be available for Xbox 360, PlayStation 3, and PC.
