The Double Mastery Weekend has started on Mafia Wars. You'll be rewarded with double mastery from doing jobs in all cities except London. Be ready to take advantage of this weekend as it ends on Sunday night. This is one of the surprises launched by Zynga Mafia Wars this weekend and there is more to come over the whole month. The month of June marks two years since Mafia Wars was launched.
So all jobs you do will pay double mastery and therefore finish in half the time. As seen from the picture below there are also going to be some sort of fight rewards that you would need to check back on Wednesday 16th to find out you Fight Rewards.
Don't waste time and get your fight rewards and help Mafia Wars celebrate two years of crime.
