The latest MotorStorm patch is now available to download and includes a number of new features and bug fixes. Among the changes include reversed tracks and 2D vehicle select. The vehicle selections lets you have either the traditional 3D select screen or a 2D grid of the vehicles to choose from, which seems to speed up the selection process somewhat.
The update can be downloaded by booting up the game and accepting the update message. Depending on your download speed, the update could take several minutes to download.
