^^^I have Gunstringer, got it for free from Microsoft ExpertZone, along with Forza 4 and Kinect Sports Season 2.
I just ordered a Kinect from Microsoft ExpertZone as well. It was only $99, and comes with three games.
Also, I downloaded the Mass Effect 3 demo (thanks to Microsoft ExpertZone, again lol). I haven't played it yet as I was finishing up another run of Mass Effect 2. I tried to get everyone killed, but Jacob and Samara survived, much to my chagrin.
