Nickelodeon All-Star Brawl

Nickelodeon All-Star Brawl features similar gameplay to Nintendo's Super Smash Bros. series, with players battling on different stages and attempting to knock their opponents outside the boundaries of the arena. Each stage offers a different layout, with some also having additional hazards that can cause damage to the characters.

The game supports local and online multiplayer for up to four players, with the game's online functionality utilizing rollback netcode on supported platforms. The game also features a single-player arcade mode and a "Sports" mode, based on the "Slap Ball" game type from the developer's previous fighting game Slap City. In Sports mode, players must knock a ball into an opponent's goal, with different types of balls having different properties, such as soccer balls being unable to be grabbed. Players are able to unlock images displayed in an in-game gallery, music for the game's sound test, and online profile icons.

Playable characters

The base game features 20 playable characters from 13 Nickelodeon series, with two additional characters to be added shortly after release. Additional characters are set to be released as downloadable content. Each character also has their own stage based on their series of origin.
