Movies, The Easter Egg - Sound FX

First turn the music volume all the way down, then go into your lot, zoom down into a set (e.g. beach or bombed street) and turn the volume on your computer up, after a few seconds you will hear Sound effects relative to that set.
(e.g. beach SFX: seagulls and splashing waves.
Bombed street SFX:exlposions and gun fire)
