Barnyard is a 2006 party game, based on the 2006 animated film of the same name. It has been released for the Nintendo GameCube, PlayStation 2, Game Boy Advance, PC, and Wii.

Introduction

Since it doesn't follow the script of the movie at all, the game instead allows the player to create a cow, boy or girl, and choose different fur colors and patterns instead of just playing Otis (who appears in the video game as a supporting character, and the boy/girl cow appears as the main protagonist). Once the character creation process is completed, the player can begin to do missions for other characters. They can also receive missions through their cellphones, via text messages. In the beginning, the player may only explore inside the Barnyard, but after several missions revolving around the main characters, the player receives a key to the Barnyard gate and a key for a bicycle, and the player is able to explore other parts of the neighborhood. Also, the missions cannot be skipped; they must be completed in order for the game to advance. Then, eventually, after a multitude of missions, the player will have to complete a boss level involving Dag and the coyotes, and then the player finishes the game and is free to roam.
