Mafia Wars District 6 Now Open

Here is Zynga's post about an hour ago:

"Mafia Wars District 6 is now open! It took 30 million fans to unlock it, and now it’s your chance to become the first among your friends to finish the Upper Strip! Go to Vegas and battle the notorious Hill Brothers to take over Sin City. The Hill Brothers are real tough, so make sure to ask your mafia to help you in this epic fight!"

Travel to Vegas now and and explore the new district! 

Like other Vegas districts, it has 3 paths : Fight Path, Social Path and Energy Path.
