Ever wanted to be a cop with superhuman skills? Now's your chance.
You can go at it anyway you like, although it's advised to o at the Kingpin last. There's not much variety in the missions here, but it's still a lot of fun. One of the reasons for that is the RPG elements. It's not much and certainly not "deep" in any way. But it adds a lot to the game. In the end you'll have a superpowered badass capable of killing people with a single kick.
Crackdown is a really good game, but it's not perfect. Driving is the worst aspect of the game, it's simply awful. Now, you can improve your driving skills, and you don't need to use cars, so it's not a major problem. Also, the game is a bit on the short side.
If you haven't played Crackdown before, and you like open-world games, then I can easily recommend this game. Now, where's Crackdown 2?
