NFSU Rivals offers a stout variety of race types. The most obvious race--a multilap circuit race--is the cornerstone of the game. You can also engage in knockout races, where the last-place driver is eliminated after each lap until only one winner remains. Rally relay races put you on the same tracks, but you'll change cars between laps. Once you get away from lap completion as a goal, there will be four more types of events. Nitrous run challenges you to make your way around a track, crossing gates that add time to a constantly draining clock, and refilling your nitrous oxide tanks. The idea is to boost around the track, hitting as many gates as you can before time finally catches up with you. Street cross races take place on smaller, often indoor tracks that flex your technical abilities rather than just forcing you to drive as fast as possible. Drift attack is the weakest race type of the bunch, simply challenging you to lose traction in special drift zones and whip around poles for points. Drag racing, a popular mode in the previous games, returns here in all its camera-shaking and blur-effected glory, and it, along with nitrous run, is definitely one of the high points of the game.
