Better than ProStreet. Original story, comfortable gameplay. Worth playing.
2. Optimization/Performance (0-10) - I'll give here 6. The FPS is low, even on fast machines.
3. Audio (0-10) - I'll give 10 of 10. Good music, good sound and realistic voice acting in the pursuits.
4. Gameplay (0-10) - My score here is 9. You can automatically start a race by just clicking the Tab button. You enter the garage and the gps map in the escape-menu. So you don't have to waste time cruising.
5. Story (0-10) - 9. Original story. You are a cop undercover. You have to earn the trust of the bad guys, do dirty jobs for them, and in the end of the story to capture them. ;-)
6. Artificial Intelligence (0-10) - I'll give here 10. The other racers are very good and skillful. Some times they can screw you bad.
7. Physics (0-10) - Maybe 7 here. The car handling is a little bit hard, and the crushes not very realistic. However this is not a big prob.
8. Realism (0-10) - NFS is arcade racing. It's just not made to be realistic. If it was the main idea in the game, it won't be so fun.
9. Total (1-10) - Nine of ten. It's worth playing.
I think Undercover is more interesting and better than ProStreet. It shows more the spirit of NFS-style.
