Secret Worlds
From Prime3
A Secret World is Metroid terminology for an out of bounds area in the game that allows the player to access areas before they are meant to be or simply explore. Due to Metroid Prime 3's dedication to limiting sequence breaking it's beginning to look like Secret Worlds will be our main route to sequence break in the first place. Please report any entrances you may find whether deliberate or accidental here or on the forums.
