Microsoft goes karaoke for Christmas with Lips, which comes complete with two wireless motion-tracking microphones. It works a treat, with the real artists providing video backdrops and easy on-screen instructions – all you have to do is follow the words and bars, scoring points for timing and pitch. Lips is also compatible with a wide range of MP3 players, which means you can add any DRM-free tracks to the game when the handful it provides pall. If you want the full video backing, however, there are only 40 tracks available so far on Xbox Live — which is far less than the likes of Singstar Abba, Guitar Hero and Rock Band. Lips is fun while it lasts and beautifully produced — but by the time you're on to the turkey sandwiches on Boxing Day, you'll have heard and seen all it has to offer.
