"Outer Heaven" is a musical theme in Metal Gear Solid: Peace Walker. It first appeared in the TGS 2009 trailer for the game as the main background theme, and was composed by Kazuma Jinnouchi & Nobuko Toda. Parts of it also play on a loop when Big Boss, riding The Boss's horse, chases Peace Walker to the Nicaraguan border.
It was later released as a DLC Walkman track for the game.
