Ape Out (stylized in all caps) is a 2019 beat 'em up game developed by Gabe Cuzzillo and published by Devolver Digital.

Financed by the Indie Fund, it was produced when Cuzzillo attended game development classes at New York University.

The game was released for Microsoft Windows and Nintendo Switch on February 28, 2019, and has garnered a positive reception.

[10] Ape Out was part of the NYU Game Center Incubator and was partially financed by the Indie Fund.

[6] The gameplay features a loud and chaotic, all-percussion jazz soundtrack composed by Matt Boch (associate arts professor at NYU Game Center)[14] which reacts dynamically to the gameplay, for example by increasing in intensity as the player faces more enemies, crashing cymbals each time an enemy is killed and adjusting the volume according to one's speed and number of kills.
