Jackass: The Game offers two gameplay modes:
MTV Story Mode: The primary campaign mode for Jackass: The Game. By playing through this mode, the player can unlock new content within the game, such as new characters and outfits.
Episodes: Stunts are collected into groups called "Episodes". Episodes in the game are similar to the format and structure of the TV series, collecting a series of five stunts which may or may not be related by a general theme. In each episode, the player is free to complete the stunts in any order.
The game contains two bonus features:
Director Mode: This mode gives players the ability to use their saved replays from various stunts and edit the footage as they see fit. Players are given a variety of different camera angles to edit each replay how they'd like. This feature is only available in the PSP version.
Theater: This feature contains actual stunts from the Jackass TV series for players to view. Theater mode includes stunts such as "The Vomelet", "Party Boy", and "The Cup Test". This feature also includes a special behind-the-scenes look at the Jackass cast recording their individual voice-overs for the game.
