This a walkthrough of how to get every skull except IWHBYD skull and alll terminals to get you the Marathon Man achievement in Halo 3.
Some answers to frequently asked questions...
You can get the skulls on any difficulty except for easy. You must start at the beginning of each level for the skulls to be there. Just pick up a skull and drop it and you will have unlocked the skull. You may end the level once you have unlocked a skull or terminal.
To actually complete a terminal you must access the terminal, wait for the alarm sound and be redirected to another set of text. You may get terminals by starting from rally points. There aare a number of IWHBYD skull tutorials, it is too long for me to add to this video, you will find a good tutorial in the responses to this vid.
