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.
If you're a fan of DVD extra features and deleted scenes (and also Saints Row), then this DLC is tailor-made for you. I captured some of the highlights in the video above to give a feel for the structure of the DLC, but the best parts aren't included.
I think the reason I had so much fun with this DLC is that it feels much more polished than the full game did, since it's so short and cuts out everything but the best parts (and jokes about doing so). I would love to see more games throw out crazy DLC like this, that doesn't cost too much, and gives you a chance to see ideas from the cutting room floor.
