The Mafia Wars blog gives past presidents more cameos. Masks for President Barack Obama ("Rock Mask"), former President George W. Bush ("Dubya Mask"), and former President Bill Clinton ("Bubba Mask") are being made available as special items for the upcoming "bank heist weekend" event.
Whoever wrote the post for the blog describes these masks in a disparaging way:
"To honor all the legendary master robbers who've worn executive masks (not to mention midterm elections are just around the corner), you'll have 5 days to collect 3 executive masks - Bubba, Dubya, and Rock."
Mafia Wars users are encouraged to send (spam) Facebook friends offering masks and asking for reciprocation. Each mask has 3 levels - bronze, silver, and gold. When you collect enough masks to complete mastery, you will earn an in-game, high-powered items that make you stronger. Those that spam enough friends and hit the "Gold Mastery" level will gain the Executive Decision (130 ATT, 102 DEF).
