Two weeks ago the XNA boys posted the 4th XNA tutorial which builds on the first three and shows how to make an asteroids game in roughly 60 minutes.



The video tutorial can be downloaded here
while the Chrome port can be found @ http://chrome.pascalgamedevelopment....NA-Samples.zip . This zip includes full source code to all the tutorials. Currently there is no keyboard support and only the XBox 360 controller via Windows XP is supported.
I'll be adding Keyboard support in a few days. The full code for each step of the tutorial, is included in the "Solved_Steps" subfolder.
