Transmission Recieved is a special achievement which contains secrets of it's own.
You must take all 26 radios outside of the chambers from which they were found. Half the radios will pick up Morse Code, and the other half will pick up fax protocols. The fax protocols can be decoded to reveal a series of disturbing, yet interesting imagery. Additionally, all of the fax protocols contain the word "Dinosaur" in them.
