This is a great game for kids like me who want to play sci-fi shooters like Halo but are (Sadly) not allowed to. Honestly, I think this is one of the ESRB's biggest fails. It EASILY could have gotten an E10, and the action is about as bad as the original Star Wars films. Though the single player campaign is difficult (And boring), the multiplayer with lots of friends is phenomenal! I have never had so much fun playing a video game. It's so cool turning into a ball and and stealthily shooting everyone else down. If the campaign was as cool, I would have given it 5 stars, easy. So, if you want a good game to pass the time by yourself, stay away. But if you are looking for a tween appropriate, fun sci-fi multiplayer experience with friends, get this game.
