Need for Speed Hot Pursuit - By far the best mode of the three available. Simply driving the car perfectly does not always result in a victory. You need to adapt your strategy to what is going on with the other cars, so keeping an eye on the radar is crucial. As a racer it goes without saying that you need to avoid the cops like the plague, attempt to make it more appealing for them to target others racers. Sometimes this mean dropping off the pace a little, especially on long routes, so you can avoid a lot of the action. Also try and avoid unforced errors such as hitting hard obstacles full on and others cars - these will expire some of your precious energy. Working as a team when playing as the cops really pays off, there is nothing more frustrating than when another cop attempts to bag a capture at the expense of the greater good.
One racer versus one cop in a head to head pursuit. The weak link with regards to the online modes, certainly nowhere near the adrenalin rush you get from Hot Pursuit mode. As the racer just try and get out of the radar of the cop. If you are the cop then simply try and take down the racer.
Race the world's most exclusive cars to see who will be the first to the finish line. It would have been nice to see the 'gadgets' enabled as a toggle option for the races, allowing spike traps and road blocks to slow competitors down. Quite simply the fastest car wins.
