Since some people were saying that there would be things hidden in the soundtrack, I played a little with "Sonic Visualiser".

In the track "Spirit", I've found a QR Code at the end:

After cleaning it:

1955 1958 1960 1961 1967 1969 1971 1977 2003 2005

What does it mean?

(It appears that others have also found it.)

    Have you checked other songs? Curious if there's anything in 'Reflection' in relation to this question Commented Apr 20, 2012 at 18:50
  • Years the developers (and a couple of their children) were born? Polytron's site doesn't exactly show how many people are in their staff, so I can't really check this.

These numbers represent years of significant space exploration achievements:

  • 1955 - "Space Race" began
  • 1958 - NASA was founded
  • 1960 - Apollo program conceived
  • 1961 - First man in space
  • 1967 - Outer Space Treaty signed
  • 1969 - First man on the moon
  • 1971 - First Apollo lunar rover launched; First Mars rover launched
  • 1977 - First Voyager space probe launched
  • 2003 - Columbia space shuttle disaster
  • 2005 - Deep impact probe launched

This was pointed out by swam2222 on GameFAQs, although some of swam2222's indicated milestones diverge from the ones that I've indicated here.


This appears to be only one of many secret images embedded in the soundtrack.

List of clues believed to be related to the monolith puzzle

It's widely believed these, and many other clues in the game, lead to the solution to the monolith puzzle. Unfortunately, it's still unknown how the puzzle is supposed to be solved, so no one knows for sure.
