The objective is to knock the ball into the opposing team's goal. The team with the most points when the timer runs out wins. Both the brawl and its maps are exclusive to the Summer Games. In the 2020 version of the Summer Games, Lúcioball Remix was added as a separate mode that includes multiple balls in action, with bonus balls worth 3 points each.
