the animated show Metalocalypse. Game modes The main mode of play in the Guitar Hero games is Career Mode, where the player and in-game band travel between various fictional performance arenas and perform sets of four to six songs. It is by completing songs in this mode that the songs are unlocked for play across the rest of the game. Players can choose their on-stage character, their guitar of choice, and the venue in which they wish to play. In this mode, the player can earn money from his/her performances that is redeemable at the in-game store, where bonus songs, additional guitars and finishes, your characters clothing and bonus content can be unlocked. Quick Play mode is a quicker method of playing songs, as it allows the player to select a track and difficulty, selecting the character, venue, and guitar and guitar skin for the player based on the song chosen. After successfully completing a song, the player is given a score, a percentage of how many notes they hit and a rating from three to five stars, and two in rare cases depending on his/her final score on the song, with money being awarded in Guitar Hero World Tour. The games have also added multiplayer modes. Cooperative modes allow two players to play lead and either bass or rhythm guitar on the same song, working together towards the same score. A competitive Face-Off mode allows two players to play against each other at different difficulty levels, each attempting to earn the best score on a song. Each player plays different portions of the song. There is also a Pro Face-Off mode, where two players battle at the same difficulty level. Unlike standard Face-off, each player attempts to play all of the notes in a song, while still trying to earn the highest score. In Guitar Hero World Tour this was advanced on, as players could play a Pro Face-Off game against each other on any difficulty level, the lower your difficulty, the more points were awarded so a player on a low difficulty could potentially beat a player on a more challenging difficulty. Guitar Hero III introduced Boss Battles, in which two players face off against each other, attempt to collect "distractions" to throw at their opponent, trying to make them fail. With Guitar Hero World Tour, up to four players can play cooperatively on lead and bass guitar,
