Mafia Wars Guard

Mafia Wars is an interesting online game where you'll be helping your hero kill members of a mafia gang. The hero’s goal is to clear up his hometown from the mafia scum. There’s a total of 10 difficult levels awaiting you where you’ll have to kill all of the mafia members, including their chief. For each level, you will get rewarded with a prize that you can then use to unlock upgrades or new friends that will help you out. During the shootout, try to spare rounds, since you will need them later. So come on, let’s play!
