Halo 3 - Yaxajax - All Mythic Skulls (Assembly, Citadel, Heretic, Longshore, Orbital, and Sandbox)
This viedo shows the locations of all 6 Mythic Skulls and how to get them. For four of the six, Assembly, Heretic, Longshore, and Orbital, you can simply fly to the skull in forge mode. On Citadel, I've found that the easiest method to obtain the skull is to through at least four gravity lifts under the skull, and then ride the lifts in spartan or elite form to the skull. On Sandbox, there is a plethora of plausible methods for obtaining the skull. I chose a method that is quick and simple - no advanced forging techniques are needed. Just make a tunnel with all of the availiable tube pieces (X menu-scenery-tube pice) and create a man-cannon a good distance out of the end of the tube pointed toward the skull. Then launch a few two-way teleporters or reciever telporters (X menu-teleporters-two way or reciever) on different channels at the skull. Change the teleporter channels by moving your cursor over the teleporter or pickin up the teleporter (making it green), pressing "X," and changing the first number. Remember the number of the channel of the teleporter that is closest to the skull (which I forgot to do) and create another two-way or a sender teleporter with the same number in a safe area. Enter the teleporter and pick up the skull as quickly as possible. You may need to do some evasive manuvers to reach the skull, but if you get the teleporter close enough to the skull this is not likely.
The song is Cut D' Midrange by Bass Mekanik.
