Right from the beggining you can see that this has not had any real time spent on it, it's deffinatly not polished in the graphics department which is a big shame really as the last Need 4 Speed for the DS (Pro-street) had pretty good graphics. The gameplay on the last game was much better aswell, the gameplay on Undercover is shocking the cars couldn't feel any less like cars, also if you hit a wall it doesn't do anything other then allow your car to keep most of it's speed so there really is no penalty for crashing.
Trying to corner in this game is so hard that you will end up hitting into every corner partly due to the handling but also due to the awful draw distance. The Music is good or should i say the one song that you have to listen to all the time. If you need anymore reason to leave this in the shop i played it for about 15-30 mins before i took it back because i couldn't cope with how bad it was.
