In Blur's career mode, the player will encounter numerous characters and many licensed cars ranging from Dodge Vipers to Lotus Exiges to Ford Transit vans fitted with F1 engines, all of which have full damage modeling and separate traits such as Acceleration, Speed, Drift, Grip and Stability. Some special car models have been designed by Bizarre Creations themselves. Albeit simplified, the tracks are also based on real-world environments, such as the Los Angeles river canals and several parts of London. Depending on the character(s) the player races against or tags along with in team races, they will have their own racing styles, power-up set ups, match types, locales and cars. As the player races well, performs stunts and uses power-ups in certain ways during races, the player will gain 'fan points'. These points help the player progress through the career, purchase more cars and parts and earn more fans for the user base. During the career, challenges will take place midrace when the player drives through a fan icon. Completing these short challenges (e.g. shoot another car with a certain weapon, or perform a long drift) will reward the player with a fan points boost. During the career mode, each challenge features a final boss, which, once defeated will yield access to their specific mods (mods being upgrades that provide enhanced functionality to a standard powerup e.g. Khan's titanium shield), and customized cars. At the final boss challenge, all the bosses meet together for a final race.
The game can be played with up to 4 players via splitscreen, and the game can be taken online for a maximum of 20 players over the internet, or over LAN in the PC, Xbox 360, and PlayStation 3 versions. In a custom game, options can be set before each match that determine the layout of power-ups, car classes, amount of laps, and the track to race. A match type called "World Tour" is essentially a quick play option for players who want to jump into a match. Here, every player is given a random car and thrown into a random series of courses with a standard ruleset. Multiplayer also offers "Team Racing" mode. Two teams (Alpha & Omega) can put themselves head to head either publicly or private. During races, each player accumulates points for their finishing position. While in team racing, powerups will not affect the player's own team members with the exception of Shock. Players can send a racing challenge to an online friend. If the second player beats the time, they can send the updated challenge back. These challenges go back and forth until one person concedes. Players can also use the Share button, and post their achievements to Twitter or Facebook.
