At level 250, Whacked Mobsters will begin to appear on your Fight List. These undead criminals are great for fighting when living opponents seem to be fewer and far between.
Unlike a normal Mobster, Whacked Mobsters don’t carry Cash and can’t be hurt. You'll be able to tell the apart on your Fight List as they'll have purple names and a small tombstone beside them.
Whacked Mobsters will only appear on your list when you've defeated all the regular Mobsters, or there aren't many available. If your list is still full of Mobsters for you to fight, the system won't generate Whacked ones for you. Keep in mind you can only fight them so many times in a day before they melt back into the shadows and disappear, but not before you get your max daily Gamer Points!
