In what is now becoming an annual tradition, one April Fools' joke is turning into an actual, real-life thing: Saints Row: The Third's "Enter the Dominatrix" expansion. THQ announced the content update this morning, identifying it as the aforementioned gag and noting that the expansion adds "freaking super powers." Oh, also, it'll cost $30. No joke!

Enter the Dominatrix arrives this fall, and it'll bring a whole new angle to the world of the Saints: "alien warlord Zinyak and his malevolent race" are apparently trying to grab up all the Earth's resources and/or women. It sounds like those freaking super powers will come in handy, eh? The dubious character seen above - named "Paul," innocuously enough - will also play some role in the expansion, which remains to be seen. THQ says we'll hear more about Enter the Dominatrix this summer, so keep an ear flap on your gimp mask unzipped for now.

Update: THQ confirmed to us that Enter the Dominatrix is a standalone expansion and Season Pass owners will have to pay $30 like everyone else.

Update 2: To be extra extra clear, THQ explained to us that Enter the Dominatrix is a standalone "boxed retail product" that can be played without owning the original Saints Row: The Third disc. It will be available solely at retail (on disc) at launch this fall.
