Once the game has been beaten you will see a Marker fully assembled on the screen. Using the right analog stick, look down and to the bottom right of the screen. In the corner you will see the mentioned/posted code. There is another code in the upper left hand corner as well. Image not shown. The codes say the following:
"In the end it all comes down to just one little thing..."
"Unity after death, unity forever"
Also, for those of you that skipped the end credits, you missed a clear indication that we can expect a Dead Space 3 in the future...hopefully sooner rather then later.
