As part of their apology, Zynga has also rewarded every player with 100 Victory Tokens and a Silenced Sniper Rifle, which has 70 Attack 28 Defense. I didn’t experience any technical issues these past days but I still received a Silenced Sniper Rifle.
Now people have a hard time beating the Feds, especially at the Gold Mastery Level. One way to beat them is to ask your mafia members for help. Hopefully a couple of your friends will help out. Or you can try to beat them on your own.
By going solo will take a long time but it is doable. Take note that you have five hours to beat a boss. During that period his health will not regenerate. But on the other hand, you can fully heal yourself through the hospital. Five hours will be enough to beat a boss. You just need to be patient and hope that your mafia members click on your help request.
