Zynga readies, aims and fires its live Mafia Wars 2 round at Facebook

Peppered throughout your travels across seven areas of the city that never sleeps--Casino Row, Granite Square, Neon Strip, Downtown, Bluebird Meadows, Boxer Island and Westside Wharf--are heavy doses of player vs player combat (PvP). In addition to invading neighboring turf, players can take the fight to three PvP arenas: Bone Yard, Badlands and Area 51. It's here where players will fight asynchronously, rob one another and spark rivalries.
