I returned this one two days after I bought it.The game is an interesting concept. And it's fun for a while. But even though there are quite a few characters, weapons and power-ups, it still won't hold your attention for more than a day in single player mode.In Xbox Live mode it will keep your interest up for a little longer (not much).The core problem is that the action is so fast that you feel like success has more to do with luck than any skill or strategy. Although your skill will improve, you still never really get to feel like you're in control of what's going on around you.Also, it is totally inappropriate for kids (kids under 21 in my opinion). Not just the topless character, but the language and movie clips are also often in poor taste.Fuzion Frenzy is a better party game.Halo and Unreal Championship are (by far) better action games.I think you'll only like this if you use Xbox Live (which I did) and enjoy a sense of panic, confusion and irreverence at every moment of a game.
