[FONT='Verdana','sans-serif']IWHBYD Skull[/font]
[FONT='Verdana','sans-serif']Go to the last tower. Before you get to the Prophet of Truth, there are a series of bridges with Halos. Do not jump through any yet. First, kill the Prophet and clear the bridges of enemies. Then jump through the Halos in this order, with "1" being the entrance and "7" being the end near where the Prophet was located: 4, 6, 5, 4, 5, 3, 4. Note: You can also use the longer sequence of 4, 5, 6, 5, 7, 6, 5, 4, 1, 2, 3, 2, 7, 2, 1, 3, 4, 6, 7, 5, 4, 5, 3, 4. This is much easier in Co-op mode with three or four people. This is the Halo theme if it was played on a phone by dialing the numbers. If done properly, the Halos will start flashing. If the Halos do not flash, revert to your last saved game. The skull is near the Prophet's ramp. Its description reads "But a dog beat him over the fence." This skull unlocks hidden dialogue when activated. If this is the thirteenth skull you have located, it will also unlock the Hayabusa Head. IWHBYD stands for "I Would Have Been Your Daddy" which is a level chapter from the original Halo.

[FONT='Verdana','sans-serif']After freeing Johnson and killing all the Covenant that come in the Phantoms in the "Sierra 117" mission, walk to the Pelican that arrives to pick you up. Face the cargo bay, but instead of hopping in turn left and follow the path. Once you hit the wall, jump up to your right to eventually reach a walkway. Walk all the way to the end. Take a left, then a right. At the end of this a little bit to the right is a dark corner. Press Up to turn your light on and you should see the skull. If you cannot see it you are probably standing on it. Its description reads "Death carries a heavy price...". Instead of only losing 25 points when you die, you will lose 75.

[FONT='Verdana','sans-serif']Mythic Skull[/font]
[FONT='Verdana','sans-serif']Follow the normal path in the "Halo" mission until you reach a cave. Hug the right wall until it branches off into a small path. At the end of this path is some rubble, and in front is the skull. Its description reads "Coverage under the Covenant health plan." It gives a 3x score multiplier for all kills.

[FONT='Verdana','sans-serif']Thunderstorm Skull[/font]
[FONT='Verdana','sans-serif']In "The Covenant" mission, shut down Tower 1 and get access to the Hornet. Fly to Tower 2 (which is the one that the Arbiter shut down). Go up the stairs. Go to the middle part that connects both. There should be a stairway that leads up to a platform where the skull is found. Its description reads "Field promotions for everyone!" Enemies will be stronger. [/font]
[FONT='Verdana','sans-serif']Tilt Skull[/font]
[FONT='Verdana','sans-serif']In the "Cortana" mission, enter the circular type room with all the Flood. Look for a small structural piece next to two archways. Jump on top if it then go up on the rocks to the top left. Turn to the left and jump up again. Turn 180 degrees and jump to the rocks across from you. Then, follow the rock that is sticking out and leads up on top of the original circular room. The skull can be found in a pool of blood. Its description reads "What was once resistant is now immunity." Enemies now have different body parts that may be resistant to certain ammunition. [/font]
[FONT='Verdana','sans-serif']Tough Luck Skull[/font]
[FONT='Verdana','sans-serif']Once you get past the part of the map after you are forced to leave your vehicles, you will go through a tunnel out onto an open "freeway". Immediately coming out of the tunnel you will see a huge pipe with two yellow ladders. Climb the second ladder. You should see a Regenerator power-up. Proceed to your right onto a small platform ledge where the yellow chain link fence is located. Jump onto that ledge, crossing over the fence. Directly behind you should be a large column that is holding up the giant pipe you were just on. Below that is a walkway. Fall off the ledge onto the walkway. Walk to the end of that. You should see a hidden ledge with the "Tough Luck" skull on it. A few attempts may be requires to jump across. Its description reads "Your foes always make every saving throw".
