Developers are already working hard at the new Zune HD with XNA Studio 3.1, with an app ported to it from the iPhone in 12 hours. Here’s another game which is included in XNA Game Studio 3.1 and can be built to run on your Zune HD. You will need Visual Studio 2008 or the free Visual Studio C# Express along with XNA Studio 3.1 to get this game to run on a Zune HD.
Here’s the complete guide on how to update it to run on the Zune HD. Check out the video below to see how it looks like. And from the looks of it, no ads run before the startup of this game. :)
