The Mafia Wars Gone in 60 Hours event has started.
Well, the Delorean is kind of a let down. On the Coming Soon page the Future Shock 1985 was pegged at 55 attack and 45 defense, but now that it is live it was knocked down to 42 attack / 42 defense in addition to providing +1 attack, +1 defense, and +5 health. I suppose its okay if you want health (??); personally I will be using the 12 hour cool-down to build more Solar Flares.
At any rate, you can now safely build a vehicle and get the 12 hour timer. You can also collect Car Parts from the Chop Shop every 12 hours too.
Double fights from loot has started, but at this point (5:45 PM EST) double mastery on jobs has not.
