How to find: Right after the first objective, while en route to the barracks, you will fall down onto a pipe. At the end of this pipe, look over the edge to see a small space a few feet below you. You must simply drop over and as quicly as you can, pull back to land under the floor you were just on. After that, the skull will be at the end.

-Blind Skull
Description: "Shoot from the hip"

Stage: First Stage

How To Find: When you get to the area where you see the Phantom overhead (one of the marines will point it out) jump over the rocks and keep following the path on the right. When you get to the cliff there will be a rock over of the side. The skull is on the end of the rock.

Easter Egg - Easter Egg on the level Halo.

by arbynthechief Jan 22, 2010

To witness this rather odd easter egg, play Co-Op with a friend, or on Xbox LIVE. Go to the last level called "Halo". Right after the cutscene, get a rocket-launcher from the downed Pelican. Travel along the path as you would if you had the main goal of beating the game. Before you reach the flood, there should be a series of long pipes, jump over to the right of them on a high-peak(do this as you would if you were finding the terminal on this level). You should see an open entrance, go inside. You should see a large, black pit. Have the person with the rocket-launcher stand behind the other player, the player should run twoards the pit. When the player is running, the player with with the rocket-launcher should fire at or near the running player's feet( make sure you don't fire too close that the running player dies). While the player is flying in mid-air, or somehow lands, they should have a view of a Bungie employee dancing in his boxers.

P.S. This is very hard, so don't get frustrated if it doesn't work the first couple of times.
