Fez

A hint: i uploaded a guide for "find all the collectibles" so i will here just giev some basics and most likely copy from my other guide which is longer.

WARNING: This achievement may glitch on you if you collect the anti cubes first as you will most likely have 33 of them then and you cant unlock this and the sum up achievement. To avoid that problem just collect all 32 golden cubes first.

Golden Cubes (32)

I won't write down the location of the golden cubes. They are scattered around the whole world sometimes in pieces sometimes as a whole so describing them would be too hard. I recommend you just play through the game normally and then check out your map by pressing back. Any room that has not been completed yet will NOT be gold so theres more to grab for you. Golden cubes and fragments you still miss are always highlighted by icons so you want to look for these to find out where you still need to search.

Anti cubes (32)

This is the part most people might be interested in as they are the hardest to find. Any room with an anti cube you haven't found yet will be highlighted with an question mark icon next to it. Also sometimes there is more than one riddle that needs to be solved in a room so always check your map if the question mark is gone or the room is golden because then you are done and can carry on.

The following part is now a location of all the anti cubes i wrote down while playing through the game i hope its all of them. if any is missing please leave me a comment so i can edit ;)

Like said i hope this is all of them but im not sure as i might have forgotten to take notes of all of them and once they are gone there is no way of checking out where you found them. Still it should contain majority and will give you a great idea on how to solve them i guess :)

Also here is a link for deciphering the riddles on your own if you should want to:
http://www.xbox360achievements.org/forum/showthread.php?t=36...
credit doesn't go to me only to the user who uploaded those codes to decipher

location of the 4 owls that are needed to solve the stone owl riddle
owls: windmill area, woods next to the house, tower next to the observitory with three eyes on it, waterfalls

you will also need to make the water sink to enter some rooms to do that simply put in the following button combination in the waterfall area and then enter the room once the waterfall opened to make the water sink
code to open the waterfall: left lt right rb up a down rt rt
