Treasure Isle & Mafia Wars: Play both to score fruit and a limited edition Reef Shark
Cafe World's made a cameo in PetVille, FarmVille has made a guest appearance in FishVille, and both Mafia Wars and Treasure Isle have had their 15 minutes in FarmVille. Now Treasure Isle is partnering up with Mafia Wars, and treasure hunters can now earn extra fruit by playing and leveling up in the mobster game.
To get started on earning your free fruit, click on the notification in Treasure Isle that says 'Click to Play Mafia Wars.' That will take you to a page that will give the details of the cross-promotion.
Once you level up, you'll receive a notification that you should head back to Treasure Isle to collect your winnings...
... in this case, a baggy of Baby Blackberries that gives you 2 energy. OK, we get that the blackberry is a kind of a dark, manly fruit worthy of any virtual mobster, but maybe we could get a fruit that's worth more than +2 energy. We still don't know whether you'll get different kind of fruits each time you level up, but we'll update this when we find out.
This whole cross-promotion goes the other way as well. Level up three times in Treasure Isle (and get past Level 4) and you'll score a Limited Edition Reef Shark in Mafia Wars. Sweet.
