Volition apparently messed up a Saints Row IV update at some point, so as a result, they've been releasing a free Thank You Pack for the fans. Today, the free DLC is available for Steam.
The Saints Row IV: Thank You Pack includes four outfits. Sort of. As you can see in the above image, one of the new outfits is kind of just a t-shirt. It's a funny t-shirt, yes, but I'm not sure you could call that a proper "outfit."
The DLC was already released to PSN, and PS3 owners can simply snag the new content by updating their game. Volition has also mentioned that the Xbox 360 version will be released with Saints Row IV's Viewer Pack 4 update this week. If you have the game on PC, just grab the Thank You Pack off Steam.
The pack's Steam page includes this description:
As a thank you for your support of Saints Row IV, please accept this free outfit pack which should be construed in no way as an attempt to get back into your good graces following a prematurely-released game patch.
Very good, Volition. Well played.
