worked with Basic Fun, Inc. to produce Guitar Hero Carabiner, a handheld electronic game that features excerpts of several songs taken from the first two games. Activision and Konami, who had previously worked together to make sure that the Guitar Hero series meets with Konami's patents on music games, in conjunction with Raw Thrills, developed an arcade console version of the game, titled Guitar Hero Arcade, distributed to arcades in early 2009.
