This new one on Live Arcade is basically real time Worms. It's very nicely put together, great graphics, fab landscape deformations, great tank and projectile physics, lots of fun with things going boom and a very well sorted online system. It found me an online game in seconds and it all went very smoothly and the demo gives you an hour on Live. One bizzare decision spoils it, you get dosh for killing people, then you buy weapons with dosh, makes you an uber killing machine, and you kill more people and clean up. Not very balanced. Great game, but not sure i'd shell out the 1200 points for it cos of that.
