Throughout the game, you can find hidden iPod music tracks. These tracks can be played during gameplay and some even have special effects, such as calming Snake's psyche or distracting enemies. They are often found in obscure locations or dropped by specific enemies. Collecting all the tracks adds a fun collectible element and allows you to customize your in-game soundtrack. Keep an eye out for glowing items on the ground or in containers. Some tracks are unlocked by completing specific story events or side objectives.
