Race difficulty:

- A.I. behaves like NFS Underground 1 "Hard" mode
- Hitting objects will slow you down even more (Except dumpsters)
- Heavier traffic

Pursuits:

- Progressive settings all the way to heat 10 (Not in other difficulties)
- Helicopters added to all heat levels
- Small chance of helicopters spawning in a roadblock at heat 4 & heat 5
- A LOT of roadblocks, spikes chance adjusted per heat level to compensate
- A LOT of police spawn in each heat level
- Police are FAR more aggressive
- Police are MUCH faster
- Police slightly heavier (Less than extreme)
