The sequel to one of Zynga's most popular social games does not seem to be faring so well according to research firm AppData which estimates that Mafia Wars 2 has lost over 900,000 subscribers over the past five weeks. The casual game that was launched back in October reached a peak of 2.5 million players but being losing out on players over the past month accounting to 36 percent of its user base. If that was not bad enough, a Bloomberg reportfrom an anonymous source says that the game has failed to generate expected sales. It was reported earlier that Zynga's offer to buy out Angry Birds developer Rovio was turned down by the company and that staff is not particularly happy with the working conditions. Zynga is about to file an IPO shortly expecting to raise $1 billion. More news on that as it goes ahead.
