Knockout City is an action video game developed by Velan Studios. Publisher Electronic Arts released the game for Microsoft Windows, Nintendo Switch, PlayStation 4 and Xbox One in May 2021 under its EA Originals label. Velan Studios took over publishing duties in June 2022, and the game transitioned into a fully free-to-play title on June 1, 2022. Knockout City is a team-based competitive multiplayer video game whose gameplay rules resemble dodgeball. The player's goal is to attack enemies from the opposing team by knocking them out with a ball. There are several types of balls in the game, including the Moon Ball, which allows the player holding the ball to jump higher, and the Bomb Ball, which is a time bomb that explodes on impact. A player can also throw another player as a ball. When ready to throw a ball, the player targets and locks on to an enemy; holding down the throw button charges up the ball for a faster shot that can be more difficult to catch. A successful throw depends not on the accuracy or the precision of the throw, but on the player's positioning and strategy. Players can dodge or catch a ball that is thrown at them, and they will respawn after getting hit by a ball twice. The player can also fake throw a ball, and tackle an opponent holding a ball. As the player progresses in the game, they will receive Holobux, which can be spent at the Brawl Shop to unlock various customization items.
