Fez

The glitch sign is on this achievement and the Hexahedronaut achievement as there is a little glitch that might give you 33 anti cubes making it impossible to unlock. To avoid that simply collect all 32 golden cubes before you have 32 anti cubes in your inventory.

If the game says all collectibles you basically need to find these:
-) all 9 treasure maps
-) all 4 artifacts
-) all 32 golden cubes
-) all 32 anti cubes

the red cubes do NOT count towards this achievement and are marked with a star *
also clearing every room on 100% does NOT count (you will need to do majority of them though)

Also this guide is written from the notes i took when i played through the game and ill try to explain as good as possible where to find every cube and what you need to do for them. However I want to warn you: they are not in order. Also i hope i didn't forget any of the anti cubes but if i should please tell me so i can edit. In my opinion a guide with some hints is better than none so i hope i can make myself clear if i try to explain anything. Really hopes this will help out.

To come to the actual guide:

Artifacts (4)

For the artifacts i recommend you check out the other guides here on TA or you follow this link:
http://www.youtube.com/user/GameFrontDotCom/videos?query=fez
no credit for these videos goes to me they will just help you to find all of them

Treasure maps (9)

Treasure maps can be found in chests scattered all over the map. To be honest i did'nt pay attention to which boxes contained keys which ones contained anti cubes and which ones contained treasure maps so you want to just check out every room for treasure maps (something you will need to do anyways to find all the cube parts). One of the maps is burnt and this is the only part of it just in case you should wonder so its actually 8 1/2 maps.

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

another great page if you should have trouble with some riddles:

I personally followed this guide step by step. It so far has been extremely helpful. Not my personal work all the credit goes to the creator.

Rowdawg88: Great guide! FYI, the counter gets kind of messed up in the video called part 7. I think it all works out, but it caught me off guard at first

You must find :
- 9 treasure maps
- 4 artifacts
- 32 golden cubes
- 32 anti cubes
For Anti cubes there is some puzzles to solve.
Like find the 4 owls (1x anti cube), solve the clock puzzle (4x anti cubes), solve the bell puzzle (1x anti cube).
