So Crack down is a free-world-do-whatever-you-want-game. It is kind of like a futuristic GTA except for you are the cops in this one. And whenever you do anything you always have like 7 cop cars pull up beside you and assist you in killing whatever you may be killing at the moment. I only played it for about an hour or so, but it is really fun becuase you can level up your abilities like agility and strength and stuff like that and you can pick up cars and throw them at people, and you can jump over buildings and stuff....
