Battle enables four players to compete in split-screen competition across varying "disciplines." The Assault sub-mode is simply a last-man-standing event in which competitors battle head-to-head. Here, options such as the track and lap count can be adjusted as desired. The Destruction Derby event, a series staple, now offers Classic and Arena variations. In Skyscraper, players aim to push one another off the roof of a tall building. Last of all is Pass Da Bomb, where the object is, of course, to not have possession of the bomb.

Smash 4 money mode is fairly self-explanatory. To earn money (functionally equivalent to points), players are expected to liberally dole out damage to any of the other racers. High-speed collisions satisfy the basic requirement for "stunts." By pulling off a Corkscrew, Teeth Puller, or Bone Cruncher, players earn these much-needed points, and also cause real-time damage to the unlucky recipient's car. Point totals and finishing place all count towards a final point tally, which is in turn measured against a predetermined value. Players must earn enough to continue on to the next event. Accumulated cash can then be spent to upgrade or repair your vehicle.
