DeviantArtist KazeXenami has built/is building a dubstep gun that should someday look like the one from Saints Row IV, and it appears that it could be kinda/sorta/theoretically partially functional, even.
Enter The Dominatrix was originally announced for Saints Row The Third, then turned into a full sequel, now it's DLC again. I think Volition found the perfect way to include their crazy story that began as an April Fool's joke.
You can't get GTA V on Steam today, but you can get GATV, a pack of downloadable content for Saints Row 4 that seems to have been created just to troll Rockstar.
Oh, yes it did. And Volition made Captain Anderson say a whole bunch more, too. You're gonna want to see and hear this, but not in the office/on public transportation/at daycare/your probation hearing.
