The social gaming giant behind "Farmville" and a plethora of other Facebook games last week stunned Wall Street by reporting quarterly results well below expectations and slashing its 2012 revenue forecast. Its stock plummeted 42 percent to a record low and analysts cut their recommendations on the stock.
Zynga's results also cast a pall over Facebook Inc because the No. 1 social network relies on Zynga for roughly 15 percent of its revenue.
In its lawsuit submitted late on Monday, the law firm Kessler Topaz Meltzer & Check LLP accused Zynga of concealing declines in users and the sale of virtual goods, the company's prime revenue source.
Zynga declined to comment.
Its shares fell 3 percent to $2.91 in morning trading.
