What does this QR Code hidden in the soundtrack mean?
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.)
Solution 1:
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.
Solution 2:
This appears to be only one of many secret images embedded in the soundtrack.
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.
