Bioshock Infinite

I absolutely loved the first Bioshock, the second one was a ok game. So i am getting really big hopes for this one.
The game is set in 1912 and takes place in the floating city of Columbia (so yeah no more Rapture), where the player assumes the role of Booker DeWitt(yes, this time we know the name of the main protagonist) , a disgraced Pinkerton agent. Booker has been given the job of finding a woman named Elizabeth(i guess she is the one in the trailer) in Columbia who has been held confined by a hulking beast called Him.
Following in the footsteps of previous BioShock games, the world of Infinite explores the chaos that results when strong ideals are taken to the extreme(Ryan anyone?). At the time of DeWitt's arrival, Columbia is a hotbed of ultra-nationalism, specifically American exceptionalism, as shown by the copious numbers of flags, patriotic music, and propaganda posters that boldfacedly spurn the idea that the Columbia could be a 'haven' from the so-called 'unwanted' of the world.
