Nickelodeon All-Star Brawl is a 2021 crossover fighting game developed by Ludosity and Fair Play Labs, and published by GameMill Entertainment.

[4] Nickelodeon All-Star Brawl is a platform fighter, with players battling on different stages and attempting to launch their opponents off the arena and out of bounds.

[5] Movement takes place on a two-dimensional plane, with characters able to move around by running, jumping, double-jumping, or performing a mid-air dash in any of eight directions.

Unique to the game is the "strafe" function, where players can hold a button to prevent their character from turning around while moving in different directions; this can be used to continue attacking an opponent while actively retreating from them.

Nickelodeon All-Star Brawl entered production by early 2020, being developed by Ludosity with assistance from Costa Rican studio Fair Play Labs.

Ludosity CEO Joel Nyström stated that "as we continue to build the Nick All-Star Brawl franchise, we will be reviewing all options, which may include adding VO down the road.

[19] Within the game's first week of release, players created several extensive mods for the PC version, including implementing gameplay changes, alternate costumes, and voice acting for all characters.

[20][21] In November 2021, the official Nickelodeon All-Star Brawl Twitter account confirmed that alternate costumes would be added to the game via a free update.

[35] Destructoid believed that the game provided a solid framework for a future franchise, and hoped GameMill would invest more time and money into a sequel.
