The single-player makes it all the more fun. Disturb actually does just that you first have to undergo training before the actual games. The two modes are very demanding:
Excite Mode: racing against computer opponents and collect stars. You can view the enemy as unfair or consider them as an additional source star. Stars you get, for example, by air jumps, scrap presses (ramming the opponents), Tree sacrilege (close to trees passing). After you have played through the race the normal Excite mode, the Super Excite mode follows, which is again a lot harder.
Challenge: The real challenge! I've mastered only partially this mode. There are: gate, Pendants- and hunting mode, the first two of a kind same checkpoint races and the last run after the Destruction Derby principle, making it the easiest.
+ Single player: very funny, especially thanks to the many bonuses and the real challenge
+ Vehicle selection and properties is just superb, each car drives differently and often you need exactly this difference.
- Multiplayer: in between quite nice.
- Music: nice that you can play your own
All in all for the price a very good game!
