Crackdown is a lot of fun. You play a genetically-engineered supercop with strange abilities that develop over the course of the game. The story isn't the games strong point, but the free-roaming RPG elements make the game a blast to play. There are many collectibles and quests to do in the game, and as you progress the game gets harder. Your mission is to wipe out 7 bosses around the city that are destroying the beautiful way of life. Cue you, to run in, guns blazing, grenades bouncing, cars sliding, to kick ass! This game is very enjoyable and is recommended, and for such a cheap price.. why not?
