Former Secret Level studio, acquired by SEGA back in 2006, has reportedly been shut down by the corporate overlords. Known for projects such as America's Army: Rise of a Soldier, Karaoke Revolution and Final Fight, the San Francisco based studio has been working on the Iron Man games for SEGA, and with the second installment apparently wrapped up, reports have been rolling in that the employees have been notified that the studio will be closing down.
