I figured it out heres two tips but im not giving away the actual code just so i dont spoil it too much

when you use eagle vision to the left of the animus you will see a bunch of random letters in the shape of the a square(to figure this out you may need a pencil and paper)but read the letters from the bottom right and move up the letters will make a word and then move to the column to the left of it and repeat till the last column put the words together and make a sentance and do the same to the triangular shape to the right of the animus both messages are pretty creepy but ive spent alot i mean ALOT of time on these messages the only ones i cant desipher are the ones in chinese if you have any questions, comments, or just need some help with the code send me a message i'll get back with you whenever i can
