Happy Birthday, Mafia Wars - Zynga's Facebook game turns two

Hard to believe that it was only two years ago that Mafia Wars launched on Facebook, and over that time the game has seen many incremental changes, which has both pleased and teed off devoted fans.

To celebrate this 24-month milestone, the mafioso game's offering double the loot for fighting for the next two days, plus a five free Throwing Knives (+65 attack skill) to help you hit rivals where it hurts. We're not exactly sure why this 'celebration' is focused fighting, though we suspect it might have something to do with the recent announcement that, in Mafia Wars Las Vegas, fighting will be "integral to conquering your enemies and completing your ultimate goal as the lord of the Las Vegas Underworld."
