Not quite. It was an idea for a SR:3 DLC title, but it grew to the point where it didn't make sense to release it as anything other then a stand alone game. The drive for SR:4 came from Volition, not the acquiring company, who only let the project go forward due to how far along it already was. The original DLC is still being released. It is "Enter the Dominatrix", the first SR:4 DLC.
