Anybody found the IWHBYD Skull ?

Question for you.

I have been unable to get the skull. I've read many web pages explaining the process in great detail. Most sites I have looked at have claimed that you have to play the Halo 3 theme song with the hologram rings in a specific order. Well....no notes come out of the rings when I jump through them.

Some sources are posting different hologram patterns, and I have tried them all. Anyone know why I can't get the notes to come out of the rings?

I'm in the right spot. Right after Truth gets killed I kill all the flood in the 3 rings rooms. Then I start at the entrance with the first ring being 1 and the ring closest to Truth being 7. I try the patterns and not only does nothing happen, but I have yet to ever hear a single note come out of the rings.Palax

I think I know what you could be doing wrong. You must play the ENTIRE level to get the skull. Starting at a checkpoint won't do it. A friend of mine and I tried it and got VERYfrustrated because we were doing exactly that. So play through the whole level again on Normal or something so it'll go quick and try it again. If you've been following all of the other instructions then this has to be it.

In this sequence ...

1-3-4-6-7-5-4-6-5-4-5-3-4

Note: Ring 1 is the one near the entrance.Ring 7 is near the prophet.

and if it is easer to read 4-5-6-5-7-6-5-4-1-2-3-2-7-2-1-3-4-6-7-5-4-6-5-4-5-3-4 long but works
