Altogether, there are six different game modes in DiRT 3. Rally, Rallycross, Trailblazer, Landrush and Head 2 Head are carried over from Colin McRae: DiRT 2, with Gymkhana being the new mode for DiRT 3.
Point-to-point races against the clock. The driver with the fastest time wins. This is only one of two modes (the other being Head 2 Head) that features a co-driver reading pace notes.
Basic circuit-racing mode. Track surfaces can be tarmac, gravel, snow, or a mix of all. Cars boast over 500bhp, and 0-62mph times of 2 seconds flat.
Similar to Rally, but with wider, more open stages. Cars are much more powerful, with up to 900bhp available.
The new mode for DiRT 3. Made famous by Ken Block's YouTube videos, drivers must pull off a variety of tricks for the crowd, such as donuts, drifts, spins, smashing polystyrene blocks, and jumps. It is a judged event, and there is no start/finish line. The driver with the highest number of points wins.
A bigger, tougher, nastier version of Rallycross. Tracks feature deep water, banked curves and jumps. Drivers race in identical Trucks or Buggies. Be careful, as the Trucks are prone to rolling over when on two wheels.
Head 2 Head Edit
Effectively a circuit race for the Rally-class cars. Instead of racing together, complex 'crossover' circuits are used, so drivers cover the same amount of tarmac before crossing the line. Co-drivers feature in these events, reading pace notes.
