Personally I haven’t had a chance to check this out myself, but the demo for upcoming tactical shooter Binary Domain is live! For now the demo is only available for gold members, so if you have a gold account you can go over here and grab the demo for free.
Binary Domain Demo
The Binary Domain Demo contains two levels and gives players the ability to check out the voice command system. With Binary Domain Kinect is not required, but it must play a lot nicer not having to wear a headset.
Anyway, if you have checked out the demo please let me know what your experiences are! If you really liked it you can always pre-order the full game!
