This is the alien language used in the Guardians of the Galaxy - Mission: Breakout ride at the Disneyland Resort's California Adventure park. I used signs containing this language and its English translation to decode the symbols. NOTICE: No symbol for 'Q' or 'Z' have been found yet, but this font will be updated when they are.
UPDATE 8/20/17: I have found the symbol for 'Z' and the apostrophe and have updated the font accordingly!
UPDATE 2 - 8/20/17: After doing a bit of deciphering of the map you find in the photo viewing room, I have finally found the symbol for 'Q'!
