Described as “soccer, but with rocket-powered cars”, Rocket League has up to eight players assigned to each of the two teams, using rocket-powered vehicles to hit a ball into their opponent’s goal and score points over the course of a match. Players’ cars have the ability to jump to hit the ball while in mid-air. The players can also pick up a speed boost by passing their cars over marked spaces on the field, enabling them to quickly cross the field, use the added momentum to hit the ball, or ram into another player’s car to destroy it; in the latter case, the destroyed car respawns moments later on their team’s side of the field.
