Anything my various history classes failed to teach me about the prohibition era in 1920's America, HBO has thankfully filled in the gaps. With all this knowledge about speakeasies and the "roaring 20's" I feel confident I can dive right into http://www.trueachievements.com/Omerta-City-of-Gangster....htm
and hold my own with the various mob families looking to capitalize on the easy money to be made. If you aren't so prepared to go Tommy Guns-blazing, this gameplay trailer from Haemimont should clue you in on the life of a made man.
Omerta: City of Gangsters
hits Xbox 360 sometime this fall.
