one player left, who technically wins the knockout competition. The standard "Tournament" mode consists of eight opponents in a four-lap race on randomly selected tracks and choices made by the player as in the knockout mode take effect when the tournament is started. The game supports network play through a serial port, modem, or IPX, and online gaming through TCP/IP protocol. It also allowed spawn installations of itself to be installed on other machines. Racing tracks range from desert canyons to countryside villages, as well as snow-capped mountain ranges. Most tracks contain one or more secret shortcuts. Car tuning was also introduced, which allowed any car's handling to be customized by adjusting low or high-end properties for engine tuning and gear ratios, front or back brake balance, slow or fast braking speed, soft or stiff suspension, low or high aerodynamics as well as rain or racing tires. Any of these options could be modified via sliders to offer a digit-sensitive, percentage-based effect to the selected car's overall performance. Higher-end engine and gear tuning, for example, will compromise acceleration for better top speed. Rear-based brake balance and slow braking speeds make for wider, drifting turns, and aerodynamics provide even higher speeds at the loss of handling. Pursuit system Hot Pursuits pursuit system has been significantly improved in terms of AI and police tactics over The Need for Speed. The game now requires that the racer only stops near a pursuing police car to be ticketed or arrested by the police, as opposed to being overtaken by a police car, forcing the racer to pull over for the same punishments. Accordingly, police cars are now programmed with the ability to block a racer's car in an attempt to halt them. In addition, whereas the original Need for Speed would only have a single police car chasing a racer in each pursuit, Hot Pursuit allows more police cars to pursue a racer, opening up the opportunity for them to collectively ambush the racer's car. Tactical aspects of the police pursuits have also been improved. The police have the ability to deploy roadblocks which has computer-controlled police cars form a wall across the road, and spike strips which puncture the tires of a racer's car, bringing it to a halt. Both tactics present weaknesses, specifically gaps in the blockade that can be used by a racer to avoid collisions with police cars, or tire
