Let's face it: this game sucks.
I thought this game would be like Crazy Taxi, or maybe something like Spy Hunter. But that's not it at all.
The goal is... well... I have no clue. It made absolutely no sense. Hence it's name, I thought you need to get to a goal in a certain time, maybe. But this game doesn't even give you any instructions of mission brief.
The only redeeming quality of the game is that you are able to smash into cars and watch them explode. The game is so glitchy and broken, that it's not even funny. Heck, if you want to get to your "destination", you don't have to go the correct path. You can just go through a building or tree for a shortcut.
Unless you want to smash cars all day, even if it's really cheap, don't buy the game. You'll get too hyped up after you order it on the internet or something, and find that it's a huge dissapointment.
