I enjoyed this game with every heartbeat of mine!
Colin McRae: Dirt 2 features five racing disciplines, all of which are playable offline (against AI bots when applicable) and online. In addition, three 'special modes' are included. Colin McRae: Dirt 2 runs on an updated version of the EGO engine, which powered Codemasters' Race Driver: Grid as well. The engine features, most notably, an updated physics engine, which models realistic weight transfer during turning maneuvers, allowing the player to incorporate advanced driving techniques, such as the Scandinavian flick.
Rally racing occurs on non-circuit roads which usually involve public (closed) routes and technically challenging courses. Usually involving staggered starts, each driver competes against the clock. In addition, during rally events, a co-driver is present, constantly reading pacenotes to guide the driver along narrow and meandering tracks of up to 6 km in length.
Rallycross races involve cars identical to those used in rally events; the races themselves, however, are completely opposite. Each rally-cross race involves up to eight racers competing in multiple lap events on circuit tracks of mixed surface type. The tracks, half tarmac and half dirt, exist in closed settings, such as in or around stadiums, and are approximately 1 to 1.5 km in length.
The most similar real-world equivalent of Trailblazer events are hill climbs. Unlike hill climb events, however, trailblazer races do not require a positive change in elevation. Similar to rallying, trailblazing features staggered starts. Trailblazer (and hill climb) cars, unlike rally cars, usually feature massive aerodynamic aids, such as spoilers, diffusers, and splitters to help keep traction at higher speeds, regardless of track surface or conditions.
Raid races are multi-car events involving heavyweight vehicles, such as buggies and trophy trucks. Each race begins with a simultaneous start of up to eight competitors, with tracks averaging 5 km in length.
Landrush events are similar to raid races, but take place on a circuit. Each event features eight racers on a dirt track of about 1 km, and involve multiple laps.

Special Modes:-
In addition to the five straight game types, there are three special variants, each applicable to multiple modes.
Gatecrasher, which uses Rally courses and cars, involves smashing yellow barriers; competitors race against the clock. When smashed, the 'gates,' strategically placed along the best racing line, add time to the clock; whichever racer finishes the event with the most time on the clock wins. The format of the race is more similar to a multi-competitor time trial than to a traditional rally race.
Domination, playable Rallycross and Land Rush stages, involves multiple drivers competing to set the lowest time in any given track sector. Points are awarded based on the final number of controlled sectors, as well as the final race position.
Last Man Standing is an elimination-style race, during which the driver in last place is eliminated in a 20-second interval.

Multiplayer:-
Colin McRae: Dirt 2 features a set of multiplayer modes which the user can partake in over, the PlayStation Network, Windows Live and Xbox Live as well as local multiplayer. Up to eight players can compete in ranked (Pro Tour) or unranked matches (Jam Session). Within the 'Jam Session' category, any class of cars may be used on any track; the game lets hosts know when a combination is not necessarily advisable, such as Trailblazer cars on a Rallycross circuit. Ranked matches are, by comparison, much more restrained; only the prescribed cars may be used on a track.
