The title is created from two Japanese onomatopoeia, pata (marching) and pon (drumming). The game is presented in a cartoonish, silhouetted 
two-dimensional environment, and features the player acting as a deity who commands an army of caricatured miniature tribal creatures by 
beating traditional talking drums. The game was developed by Pyramid and produced by Japan Studios.

Patapon is a video game that the player controls in a manner similar to rhythm games. The player is put in direct control of a tribe of Patapon 
warriors; to command the warriors, the player inputs specific sequences using the face buttons on the PSP, each representing a "talking drum",
in time to a drum rhythm. These sequences order the tribe to move forward on the linear battlefield, attack, defend, and other actions. 

The Patapon Tribe were flourishing people until they experienced many tragic losses and later on, they were maltreated by the Zigoton Empire (although Ormen Karmen of the Karmen Tribe originally defeated them and overtook the Patapole
Palace). The player takes the role of their god, the "Almighty", and uses sacred war drums (Pata, Pon, Chaka, Don) to direct the Patapons to recover their land. As the story progresses, 
the  Patapons embark on a journey to Earthend to look upon "IT", a sacred object whose appearance is unknown to the tribe and its purpose is to  grant the Patapons eternal contentment and true happiness.
