More than 11 million copies of games in the Saints Row franchise have been shipped worldwide, publisher THQ has announced.

This make Saints Row THQ's most successful owned-IP franchise.

Of the 11 million, 4.35 million units are attributed to Saints Row: The Third, which has also generated the highest digital revenue of any console title in the publisher's history.

Hoping to build on the third game's success, THQ is releasing standalone franchise extension Saints Row: The Third - Enter the Dominatrix in September 2012. The game promises even more over the top action thanks to a virtual reality setting and superpowers.
