One of the many different collectibles (if you would call it that) that can be found throughout Oddworld Soulstorm are the Secret Areas, these areas are often hidden and despite sometimes being difficult to get to they can provide some really good uses too, as they often hold other more valuable collectibles such as the Royal Jellies, Mudokons and more..
They also help contribute towards collecting all of the various different mission and stage badges and ultimately the Gameplay master, platinum trophy achievement too.
Anyway below is a list of stages and missions in which you can find these Secret Areas on, and of course how to actually reach them too.
