Grunt B-Day Skull
Difficulty: Legendary
Level: The Arbiter
Effect: Shoot enemy in the head and they will explode.

The very first time you get a Banshee, fly down. Below you is a large beamlike structure (not to be confused with the one directly below you that turns and goes vertical) running from the arm of the station you just came out of to one exactly like it on the side opposite. Below this structure are 3 cylinders hanging down, with cylinders of light shooting out of the bottom that look like they are what keeps the station floating. If my explanation is too vague, they are the absolute lowest parts of the station. Now go to the middle engine and land on the top part of it. This and the other engines connect to the large structure mentioned earlier. The tops of the engines come up to meet the structure at an angle, where this angle is under the connecting structure and coming up to meet it, there is a place to walk (like being under a bridge). Under one side you will see the six grunts with the skull in the middle. 

Blind Skull
When you start off Outskirts (They'll Regret That Too), walk over to the 1st door and look up at the halogen light, then jump up on top of the light. Then look up at the wall with the stripes and jump toward it. You should land on top of the lower roof. Once you're up there turn right and you should see a dark hallway. Walk to the end of the hallway and look look down to find the skull. Pick up the skull by hitting the X button. Be WARNED this is the "Blind Skull" so your motion sensor, your gun, and entire HUD will be erased. To stop blindness turn off your Xbox and start over. ( do it on legendary)

 	
Assassins Skull
Difficulty: Legendary
Level: Regret
Effect: All enemies in game are permanently cloaked, AI cannot see them and so are no help at all.

In the level Regret, on Legendary Difficulty, immediately after the gondola ride following the battle with the Hunters, there will be a building with two turrets on it. Enter the building and turn to your left. There will be a box. Jump on it. From there jump to the adjacent light fixture, then to the ledge. The ledge leads to the area with the two turrets. Once there use a grenade jump to get onto the roof area, then, using croutch jumps and grenade jumps, follow the right side perimeter of the building. Once you have gone as far as you can go you will find a small grassy area with two cloaked dancing elites and the Assassins skull. Once you pick up the skull all enemies will have active camoflage. 

 	
Iron Skull
Difficulty: Legendary
Level: High Charity
Effect: still busy finding it out.

On the last Master Chief Level, on Legendary Difficulty, when you enter the final Gravity Lift, look up. A skull will pass through you extemely quickly so you must start holding "X" a bit before you actually pass it to grab hold of it.

 	
Envy Skull
Difficulty: Legendary
Level: Delta Halo
Effect: Master Chief cloaks like the Arbiter

On the level "Delta Halo" on Legendary Difficulty, progress until you reach the area during the "Push through the covenant held ruins" scene where you have to clear a Landing Zone for the Pelican to drop weapons. I beleive you will know you are in the right area when Cortana says "They're pouring out of the center building." The area has Plasma turrets along its borders. A little bit past the left side turret you will see the outline of a door in a wall, but the door has a solid rock slab in it and a rock in front of it. Jump on the rock then jump to the ledge above the door, then jump on the ledge to the left. Now jump onto the building with the sealed door using grenades. Atop the building you will find two dancing elites and the "Envy Skull". Pick up the envy skull and you will be able to use Active Camoflage like the Arbiter.

Thunderstorm Skull
Difficulty: Legendary
Level: Cairo Station
Effect: Covenant vehicles are more resistant/ All elite forms take their highest level.

After you take out the second room of Covenant boarding the ship, the game says "Priority Shift". Shortly after this you will go to the armory where you will have to take out a couple of Elites. The next room is "Commons B.01" (a large room with trees and a window at the end on the second floor that has a plasma turret. The skull is on the highest ledge behind you, above the doorway where you enter this room. Take out all the baddies and proceed to the window with the turret. Jump to the left onto the ledge from the window. You'll notice several diagonal supports that lead up to two thin rails that run the length of the room. Make a well timed jump/duck from one of the diagonal beams to the rails. Follow the rails all the way to the other end of the room and you will see a ledge on the left with a trash can. Knock over the trashcan to reveal the "Thunderstorm" skull. 

Angry Skull
Difficulty: Legendary
Level: Grave Mind
Effect: (not sure but I thought these where the effects)
enemies have more accurrecy, are less cowardly, are more agressive and more clever.

Fight all the way through the Covenant city until you reach the outdoors. As soon as you are outside, stick to the right-hand side and walk along the wall. You should see a Covenant wall thingy with a red rail on it. Jump up to it (crouch jump helps) and at the end there is the Angry skull in a small grav-lift. ( a dark green grunt is guarding it, look at his ranks at the rank page to know whats his speciallity)

 	
Catch Skull
Difficulty: Legendary
Level: Metropolis
Effect: ???

Right after you get out of the sewers (Tunnel), there is a big area with 2 Ghosts. Kill every thing first, then go to the middle where you see a arch that leads up onto a building. Grenade jump to start climbing it. When you get to the top take a left and hug the wall around the structure and the skull will be there. 
another way: when your near the arch go to the next part, steal the wraith and go back to the arch( use the stairs to get up with the wraith) drive against the arch for the front. if done correctly, you can jump on the wraith and walk to the end

 	
Infinite Skull ( I copied this but I still couldn't find it)
Difficulty: Legendary
Level: Quarantine Zone
Effect: Infinite energy sword and leap kill from far away

Get the tank and find the holes along the walls. Take a tank to the one with a cliff right above it and back the tank up against it and up the hill backwards. Get out and climb up on the tank, then grenade jump to the next part. From there you can go anywhere and the skull is on the opposite side of the level. 

Famine Skull
Difficulty: Legendary
Level: The Oracle
Effect: All preset human weapons that are picked up start at half ammo

There should be a glass thing in the room after you kill the first few Flood. Go in there, break the glass and then crouch jump to the whatever it is in the middle of the room, some type of glass structure wall type thing. Now jump to the opposite side of the wall you came in on, on the ledge, and the skull is there. 

Sputnik Skull
Difficulty: Legendary
Level: Quarantine Zone
Effect: Low gravity effect (only a slight difference)
From the start of the level, look to your left for an Elite. To the left of the Elite there is a tunnel. Head into the tunnel and go straight until you reach a cliff. Now turn left and follow the cliff till you reach a rock wall. To the right of the wall and the cliff is a narrow passage, skull is at the end of that passage. 

Mystic Skull
Difficulty: Legendary
Level: Sacred Icon
Effect: ???

There is a semi-outdoor area which has a similar area right next to it. There is a large sentinel in front of each one. Go past this area and down the piston and you'll be in a very dark and dank Flood-infested area. There's a stack of boxes as you enter the room: use them to jump up to the right ledge and the skull is in a vent floating above a dead Human/Flood .

nstant Ghost Destruction
Entry Location:
Works in campaign, any level, and difficulty, and even multiplayer!

On the left side of the ghost (left side to the drivers perspective), there is a small circle like object jutting out. I call it a gas tank, as it is a very easy way to destroy a ghost and its driver. All you need is a battle rifle (the best weapon to use for this), or any other HUMAN weapon. Just shoot the "gas tank" with with you human weapon (one shot with B.R. should do it), and the ghost will instantly blow up, along with the driver.

use swords against parasites

melee against jackals

snipers versus elite and brutes( headshots)

plasma granades, brute shots and dual needlers against higher ranked

cya folks when i update!
