Mafia Wars: Las Vegas is almost here , and this Saturday, July 3rd, you’ll get a chance to loot exclusive “Vegas Chips”. These chips will give you an advantage when Vegas releases, so you’d better collect as many as you can get ahead of your Mafia rivals. If that wasn’t enough, Sunday and Monday (4th and 5th of July) will be a special double-double event. Mafia Wars fans, clear out your weekend for some serious crime time.
