Each zone has its own individual cheevo page.
On this page is a link to the guide for PERPLEXING PUZZLE PIECES
PERPLEXING PUZZLE PIECES
Completing this cheevo will unlock the ability to buy the Toks decoder ring (info here)
There are 5 boxes hidden in each of the 4 original Celestial zones.
For this cheevo.. I am simply going to link Forbidenlakes guide.. I wouldn’t normally do this, but his guide is so precise and complete that if i would make my own it would just be a copy and paste job of his!
so.. please see Forbiddenlakes guide
