Gameplay in MSR is centred around the single-player mode, with tracks and cars in the multiplayer mode being unlocked at the same time as in the single-player game. The premise is that, as a street racer, the player must impress other drivers with quick but stylish driving in a series of challenges. These challenges are in sets of ten (called Chapters - there are 25 in total), with completion of all challenges opening the next chapter (assuming the player has enough Kudos, see below) and unlocking a new car. Each challenge is on a different track, and unlocking a challenge unlocks that track in the time-attack and multiplayer modes.
