This game can be played by one or two players.
Single Player Quickplay mode is a one-player mode where you select a team and play a one-off game against a team of opponents controlled by the game.
After selecting this mode, you'll select your team, your opponents, and the track where you intend to have your bout. You may adjust your roster at any time before or after jams, but never during a jam.
When the bout concludes, you'll have the option to play another bout against the same opponents ("Grudge Match") or to return to the Main Menu ("Continue").
