Racebreaker is a nitrous refill gameplay mechanic featured in Need for Speed: Underground 2. It works in conjunction with a Nitrous Oxide upgraded vehicle.
Gauge with nitrous bar in Need for Speed: Underground 2
Unlike Need for Speed: Underground, nitrous is no longer limited and can be regained through the Racebreaker feature. It will restore a certain amount of used nitrous capacity upon the player performing driving stunts or giving themselves an competitive edge in a race. The player can fill up to two nitrous bars, with the second bar being highlighted by a brighter colour.
Several Racebreaker actions will be multiplied the more often the player is able to repeat them. However, the multiplier will be reset if the player fails to meet an action's prerequisite by crashing with a traffic car for instance.

Nitrous Purge[]
Nitrous Purge is a Car Specialty that sprays nitrous out of valves under the hood when activated. It can also be sprayed out of the front wheel wells if upgraded.
Notes[]
- Exiting a Shop refills one nitrous bar.
- The use of a filled Nitrous bar is more effective than several smaller doses.
