This is for players on all modes. If you are having trouble getting killing all the of the flood people, try using grenades (preferably plasma or spike). If that doesn't work try using your fuel rod gun. Depending on how many missiles you have and your health, it should give you an advantage against the flood. If that doesn't work, there is an extra fuel rod gun near the enterance of wer your checkpoint is. When you start off, automatically go left on that pile of snow and look down. You should see a fuel rod gun very near.

I found this sticker thing that kinda looked like a color code from an image editing program like paint shop pro or photoshop. It's in the fourth level right where you fight the first AA wraith. It's probably easiest to kill everything first before you try this. All you need to do is go to the wall right where that big cylindrical building with the catch skull is. Jump up onto one of those pipes jetting out the side of the wall. If you look where the wall is that kinda "oily" color, (when you see oil on the street, how it was all of those cool color's in it), and every now and then there will be this sticker that has the same color code on it. It's blurry and kinda hard to read, but I think it said from top to bottom: R: 147, G:152, B:152, and some letter I can't make out that might be an L and the number for that one is 255. Also, if you go along the side of the wall to that thin, forked pipe towards the end of the wall, there's a mirror image of the sticker. The color itself is a kinda light blue, I think.

On the covenant level when you are in the first struture turn left and go in the opening go up the ramp to the hole in the wall. Get close, then jump onto the pillar to the left. If done right you will stay on the top of the pillar and you can walk around and jump into the hole then go and jump onto the elevator. Simple and effective!

On "halo" the easy way to do this is when you meet the flood back all the away to the cliff behind you and let the arbiter kill them all. When you think you can get through go and then find a safe-point and repeat until you are inside the structure. To end the level let the arbiter clear the path and run all the way to the warthog. Then complete the level and as a little bonus you can watch the secret "legend" ending by not skipping the credits of the congratulations note by bungie.

So here is what to do: Play through the level once. Then go to theatre. While youre watching the level, you can float around and see where they are without worrying about being shot or falling to your death.

Ok all you have to do is put a lot of fusion coils and plasma batteries inside the elephent, and then set the run time maxium to the highest it will go on both of them. Then set the run time minimum as high as it will go. Blow the thing up and it will never touch the ground again!

Ok, I'm surprised nobody has put this on here yet, so I will. In forge, spawn a tank and push it against the crane of the elephant. This flips it, and is much easier than trying to use the fusion coils. Then, when you try to flip it, it says something like "click RB to flip... wait... what? how did you do that"

Have a friend in Forge mode. When you start the game, spawn a Brute Shot. Have the player who is not the host turn in to a Monitor. Have the host remain a player. Have the Monitor look at the Brute Shot as if they are going to pick it up. Have the player look as if they are going to pick up the weapon. Do a countdown and have both players take the weapon at the same time. This may require a few attempts.

Best of the weapons to have fun with.
1.Spartan Laser:Invisible beam = Invisible Ownage
2.Snipers:Invisible shots = Invisible Ownage
3.Brute Shot: Shoot a guy in the back from behind yourself

4.Sentinel Beam: Only you can see the beam.
5.Plasma weapons: Auto-Ownage-matic

In the level "covenant", rally point 2, after you kill all the banshees flying around, kill the tank to the very right. When your done, go and land. There will be a small hill. On that hill, you can find a fuel rod gun. With it, you can kill the hunters coming up in one shot! This is perfect if you hate trying again and again to kill both of them.

When you're escorting characters to their ships on the second level of the campaign, you can head the wrong way from where you're supposed to go. If you do, you'll run into two characters that are separated by a door and having a great conversation. It's pretty funny and worth checking out!

Black Eye (Located: Crow's Nest)

When activated, you will have to battle enemies with melee tactics to regain shield energy.

Catch (Located: The Storm)

When activated, enemies will throw more grenades.

Famine (Located: The Ark)

When activated, dropped weapons will hold less ammunition.

Fog (Located: Floodgate)

When activated, the motion tracker disappears.

Iron (Located: Sierra 117)

When activated, you will be sent back to the beginning of the stage you're on when you die instead of to the last checkpoint.

Mythic (Located: Halo)

When activated, all enemies will have twice as much health.

Thunderstorm (Located: The Covenant)

When activated, enemies will be of a higher rank.

Tilt (Located: Cortana)

When activated, enemies will become more resilient to your attacks.

Tough Luck (Located: Tsavo Highway)

When activated, enemies are skilled at getting away from projectiles such as grenades.

This is really just a suggestion. If you're want to play the last level on Legendary, but suck, this little bit of info. You might find this very helpful. All you have to do is nothing but walk behind the Arbitor as HE kills all of the flood. Somehow, Bungie made the Arbitor very powerful and he VERY rarely dies. But if that happens, just walk up to him and he'll come "back to life". Because of all this, the last level is probably the easiest level on legendary. The only "hard" part is killing the Oracle and driving to the Frigate. But if you can do all of that, you'll find playing the last Level on Legendary as easy as playing it on the newbie easy difficulty.

This is great for making walls or corners. Spawn the first object and set the respawn time to a decent time, long enough for you to get back to that item and place other one. Set it to not spawn at the start of the match. Then, start a new round go to where the item was spawn another one in its path and then when the first item spawns, the two will be morphed together.

Have you ever wanted to get rid of the shield doors on Snowbound and make yourself invisible to the plasma turrets? Now you can. Here's how:

1. Go into forge on Snowbound. 2. Spawn 4 Trip Mines in a pile in an open area. 3. Set their run time minimum to 4. 4. Stand on the pile (which makes you pick up a Trip Mine). 5. Look diagonally up while still standing on the pile. 6. Throw Trip Mine. 7. Repeat steps 5 and 6 until the pile suddenly explodes.

If done right, the shield doors on Snowbound should be gone.

This can be done on other maps for other effects.

The people who made this game naver intended for us to use the banshee in this level. When you have to face the 2 scarabs, just fly around in the hornet for a bit and dont blow them up. Look above the scarab on the right, there should be a medium size ship. Fly over it/ above it. Go to the right side and jump out. 2 banshees will be over there shooting you. Start shooting. One will come at you slowly so hold the RB button and wait till it comes close and jump at the side of the banshee.

On any Campaign map that features this vehicle (The Covenant is best for learning how to do this glitch as there is an Anti-Air Wraith right at the beginning), hop onto the bonnet of an Anti-Air Wraith, and melee it until the hatch falls off and the driver is exposed. Melee him ONCE in the head to make his helmet disappear, then get behind him. What you need to do here is make sure that the "Hold RB to board" prompt is NOT visible, but you DO need to be aiming at the Brute's head, so basically you have to manouever yourself in such a way that you're close to the Brute but not too close. Try crouching down then aiming. Once you've got a clear shot of his head, hold RB then shoot; if you've done this glitch correctly, Master Chief will hop into the Anti-Air Wraith and you can pilot it exactly like the standard Wraith.

Something very interesting about this vehicle is that it has its own cursor and exit animation (the cannons fold in on eachother), so Bungie clearly intended for us to use this vehicle but apparently removed it at the last second.

You can hold down the fire trigger to release a constant stream of Fuel-Rod Cannon bullets which is immensely destructive; you can take down a Scarab in about 5-7 hits to the legs, or you could just shoot it in the back to expose its core then destroy it from there.

If you try and exit this vehicle it will explode.

Have fun.

Blind (Located: Sierra 117)

The arms of the player and the motion tracker disappear.

Grunt Birthday Party (Located: Crow's Nest)

If you manage to get a headshot on a Grunt, the Grunt will explode.

If you are having trouble sniping here are a few tips,

-Try practice by throwing a plasma grenade in the air, then blow it up in the air by sniping it, it takes practice but once you get the hang of of it, you should be a better sniper

-When some one is about to enter a room, have your cross hairs roughly where their head will be, then adjust it quickly [it should be pretty easy] then hit them in the head or shoot then hit them.

-If your a beginner, its easier to just shoot at the body

-Don't stand still always move so that your harder to hit while sniping

To jump reaaaaallly high, first, position yourself properly atop your friends head. Then, jump. Have your friend jump immediately after. As they jump, thier head will hit your feet in midair, allowing you to jump again. This will allow you to jump 3x the normal jump height.

And a WARNING:

Before heading to the pelican to end the level "Cortana" Ensure that you have some kick ass weapons with loads of ammo, because this is what you'll be stuck with fighting off an army of flood on the next level.

I reccomend some really good close range weapons(i.e. shotgun, plasma sword, etc....) But definitely get the rocket launcher just in front of the pelican. It's a life saver.

Also, when fighting those little dudes that transform and start shooting needles at you, DO NOT USE A RANGED WEAPON. While things such as the sniper rifle and carbine do excellent damage to most other flood, it can take a LONG time to kill these guys this way. the best approach? Rush 'em, and blow 'em to hell with a rifle, shotgun, hammer, or plasma sword before they jump away.

At the end of the last level, Halo, when you drive under a cresent made by some rocks, turn to your right, and look around for a bit. You'll see a grunt who won't attack you, only talk to you.

To Use a Pantom Turret Go to the first Mission And Do Not Kill The Grunts on The Turrets then Kill everyone else down there When the Pantom goes to fly away it will get stuck near the crash Pelican kill the Grunt on Your Side Then The Arbitar will Try to killthe other but It will be Stuck Between a rock and the Pantom Then Jump on The Rock Nearby and then jump in this may take a few times because some times you fall through it once on slowly walk toward the turret till you just barly get the message saying press RB to operate turret then you have a Pantom Turret To get around it Jump on the small part of the big rock near it then jump on the tree branch then the top part of the rock and you should be able to get on the path ahead.(Note: I did this on Co-Op on Lendgendary and it may not always happen I don't know.)

Yep it's true. You and a friend get in a dumpster and start jumping one after another. Eventually the dumpster will lift off and you'll start flying around in the air. Just make sure not to stop jumping or you'll drop back to the ground.

If you're trying to get this achievement on Tsavo Highway, turn the Cowbell skull on. The increased explosion is slightly enough to help you destroy enemy Choppers.

1.First make a brigde float in the air 3 double boxies high.
2.On the edge of the brigde place a fence box a bit bent so it starts swinging up and down.
3.Then qiuckly get in and walk forward and backwards when you go forward you press B so you melee.
4.When it comes off just put it back on.

1.Turretless Warthog,wraith,prowler,scorpion
Stuff Needed
Forge on A level with this vehicle
2 players
have the person who is NOT the host go into forge mode and go to the vehicles section the have them scroll down to one of those vehicles DONT
have them place the vehicle and then the host will end the round but the non host player will place the car when the screen goes black and now go to the place with the turretless vehicle was spawned and drive it around

Ok in order to do this once you get out of the third tower after deactivating it make sure you have at least one or two firebomb grenades in your inventory or both spike grenades. Before the arbiter gets in the Phantom throw either the firebomb or the spike grenade at him and kill him. If done right the phantom will not take off. If you really want to have some fun kill all the marines and elites (if there are any surviving elites)and get in the scorpian and the arbiter will man the turret or drive the tank whatever pleases you. Then once you get to the part where you fight two scarabs and beat them drive the tank up to the citadel platform where there will be another arbiter. Drive up to the door and make it so that the tank will blow up after the door closes. If done right the arbiter that you brought from the third tower with you will die. If done correctly the arbiter from the third tower will show up right before you kill truth. If you want a third arbiter kill the arbiter in the citadel right before the cutscene initiates but this must be done right after the door closes. If you want to do it right wait till Cortana is done interupting the game then right before Truth comes on the comm link and video screens throw either a spike grenade or firebomb grenade at the arbiter that is supposed to come with you to kill truth and watch it kill him before the cutscene. Then if you want three arbiters assisting you in the fight against the flood try to kill the arbiters like you did before. But if you want to have three of them you must have picked up the grav hammer then knock them off the edge and then activate the bridge. If you done this right you should have glitched Halo 3 and have three arbiters at your side. I have yet to get four arbiters. When I do I will post and let you halo 3 fans know how I did it.

Your fellow Halo 3 fan,
Razor the swat cat.

When you're escorting characters to their ships on the second level of the campaign, you can head the wrong way from where you're supposed to go. If you do, you'll run into two characters that are separated by a door and having a great conversation. It's pretty funny and worth checking out!

-----The voices are actually the guys that do the Red vs. blue videos.

Grunt Birthday Party skull
Effect: Headshots on grunts cause heads to explode with confetti.
Where to find: Crow's Nest

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.

Black-Eye Skull
Effect: Melee hits instantly recharges your shield.
Where to find: Crow's Nest

How to find: As soon as you start the level, head straight up to the higher level. Head toward the door with the red light, then turn around. Jump onto the racks, onto the red metal light holders, then onto the ventilation tube. The skull will spawn 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.

Note: This skull has to be Activated before you start a Campaign map.

Iron Skull
Effect: When either player dies in Co-Op on any difficulty both players will restart at last check point or in single player if you die you restart the level.
Where to Find: Sierra 117

How to find: In the area where you rescue Sarge, behind the prison cell is a large ledge. Got to the far right side and jump on the boxes, then onto the pipes to get up on the ledge, goto the far end of the ledge, turning two corners the skull is at the far end.

Tough Luck Skull
Effect: Enemies do saving throws
Where to find: Tsavo Highway

On Tsavo Highway, about halfway through the mission (right after you are forced to walk through a large blue barrier), you will come out of a tunnel on the highway, and see a large pipeline on your left. Drop down in between the two, and run to the wall in front of you. Follow the wall all the way to where it connects with the cliff on your right, and turn to the left. There should be a few ledges--simply crouch jump from ledge to ledge, and the last one should have the "Tough Luck" skull on it.

Mythic Skull
Effect: Every enemy on the field now has double their normal amount of health.
Where to find: Halo

How to find: As soon as the mission starts walk up the hill in front of you and into the cave. Hug the right side of the cave and after a large boulder you will see a path on your right, just take the short path and it will be at the end.


Cowbell Skull
Effect: Explosive force increased (sputnik from H2)
Level: The Ark

Location: First pick up a grav lift from the small building near where you fight the scarab. Now proceed through the level until you reach the second sloping hallway (stairway), you should see some partitioned risers (platforms) halfway down. The skull is on the top level. Toss the grav-lift on the right side of the hall so it lands on the fourth little green dot from the door. Then run, jump, and use the grav-lift to propel you to the top. You should reach a ckeckpoint just as you enter the room so it you miss just try again.

Thunderstorm Skull
Mission: The Covenant
Effect: "Field promotions for everyone!" -- Upgrades enemies to their stronger versions.

After you shut down tower 1 and get access to the hornet, fly to tower 2 (the one the arbiter shut down). While walking up the stairs, go to the middle part that connects both and there should be a stair leading up to a platform where the skull is.

The 7 Terminals
The Ark:
1. Start the mission and once you enter the first building take a left into another door and now you should be in a curved corridor. On the inside is a Terminal.
2. After activating the bridge to let your comrades accross the gap, do a 180 and you should see it. (it does not open until you activate the bridge)
3. In the third building after defeating the scarab, kill the group of sleeping covenant, then follow the corridor downwards. Once you reach a door in front that is locked, immediately on the left there's an open door. Go through and walk straight off, then do a 180 to find a secret room. It is in there.

The Covenant:

1. When in the first tower standing on the lift, face the access panel and turn left. Jump over and it's right there.
2. Land your hornet on the second tower, walk towards the entrance but when you see the locked door, do a 180. Should be right in front of you.
3. When in the third tower standing on the lift, face the access panel and turn right. Jump over and it's right there.

Halo:

1. After reaching the end of the first cave, hug the right wall and you will see a building. Jump up onto the walkway and hang a left once inside. It's right there.


Fog Skull
Mission: Floodgate
Effect: "You’ll miss those eyes in the back of your head." -- Your motion sensor disappears.

As you are walking down from the anti-air gun you destroyed in the previous mission, you encounter a ramp (next to a missile launcher). Around this ramp, you hit a checkpoint. At this point, you should also hear a marine yelling, “There! Over There!”. Look up and to the right, directly at the roof of the building next to the missle launcher. There is a single flood form (not to be mistaken with the two other flood forms jumping in front of you) which is holding the skull. Kill him before he jumps, and he will drop the skull down to the ground where you can retrieve it. Too early, and the skull will get stuck on the roof though, so just time it carefully.

Famine Skull
Mission: The Ark
Effect: "Trust us. Bring a magazine." -- Dropped weapons will have very little ammo compared to normal.

When you first go into the valley to the right after the wrecked phantom, look to your left where you will see a huge boulder. Use a ghost and get to the side of the boulder that is closest to the bridge overhead. It is easy to pilot the ghost up the side of the wall using the thrust. To get the skull, pilot 2 ghosts up the wall to the top of the bridge and stack them one on top of another next to the beam where the skull is placed. Simply jump from the top of the ghosts towards the skull and land on the beam.

Tilt Skull
Mission: Cortana
Effect: "What was once resistant is now immunity" -- Enemies have different body parts that may be resistance to certain bullet types

When in the circular type room with all the flood look for a small structure piece next to two archways, jump on top if it and up on the rocks to the top left, turn left and jump up again, then do a 180 and jump to the rocks across from you. After that follow the the rock sticking out and leading up on top of of the original circular room, the skull will be in a pile of blood.

IWHBYD Skull
Mission: The Covenant
Effect: "But the dog beat me over the fence" - Unlocks bonus dialogue throughout the game. For most, this is the last skull, so this gives you the Hayabusa Helmet as well.

To get this, get to the room where you "fight" the Prophet of Truth. Let the Arbiter kill him, turn around, and kill all the Flood here as well; makes it a LOT easier. With all obstacles out of the way, you need to jump through the Halo holograms here in a specific order, listed below:

4 6 5 4 5 3 4

When you jump through the final hologram, they all light up in a sequential pattern. The Skull will be at the end waiting for you right before the energy bridge leading to Truth's corpse.


Catch Skull
Effect: all enemies have 2 grenades, throw more grenades
Level: The Storm

Location: From the start, go through until you go outside again. When you go outside look straight across there is a small round building straight out there, the skull is on top. In order to get up there you can either use a warthog as a platform or grenade-jump. DO NOT destroy the wraith near the door or the skull will disappear.

This is for all players on all modes. If you are having trouble driving your way through all the obsticles in your way trying to deactivate Halo, try using shortcuts. In the beginning, once you get in the teminal, keep going straight until you see that passageway in the middle.(NOTE: Drive slow! If you drive fast you have to start from the beginning of that mission.) If your partner is keep you from victory, ditch him. Remember that although it is Campaign, this mission is about getting out alive.

This is an easter egg. At the beginning of the Crow's Nest mission, go get a gun from armory downstairs, but then go back upstairs and find Captain Keyes. If you do some beat downs on her, she'll scream in a really high feminine voice, which is hilarious.

All these should be in forge.

Elephant ontop of elephant:
Find an elephant and make a wraith. stick it in so it is stuck and move it ontop of another elephant, you can even drop it high in the air.

Elephant Ctapult: Fill it with as many fusion coils and plasma batteries and go inside and smash with gravity hammer to get lauch high in the air and even get on a great sniping point.

Elephant wars: This is great when doing capture the fllag. One elephant will be a covenant and one will be UNSC. Fill the Covenant by placing a wraith ontop of the elephant on those stick sticking out on the top so that you can fire ontop of the elephant. Place a banshee ontop of the cockpit and put as many ghosts choppers and prowlers as you can fit. For the UNSC one do the same you did with the wraith to the scorpian. Place a hornet ontop so its wings get stopped by the sticks. Place a guass warthog to the side of the cockpit and mongooses and warthog wherever you want

Custom power-ups can only be used in Custom Games. The custom power-up you can add in the Forge will greatly affect your game depending on how many you have and how fast they respawn. You can only adjust the custom power-up before a match. Be sure to write down what effects you are looking for in a custom game.
Press BLUE to edit the match options in a Custom Game. Go into Weapons and Vehicles, then locate the Custom Power-up Traits.

on the first level on heroic, after killing all the jackal snipers in the ravine continue along the wall up high to where the first jackal on the left was. once you get there follow the wall (yuo may have to jump around to stay on) until you get to a corner, and voila there they are.

PS one is holding a stuffed bunny doll

First make a item that cant be moved like a Double box.
Put something on top of it
Delete it
Bam the object will be floating!

Great for making fortesses that you have a ramp to enter

This is how you fuse objects such as boxes together in Forge.

Spawn an object and set the respawn time to like ten or twenty and make it so it doesn't spawn at the start. Start a new round and it won't be there so make the next object in it or however you want them to fuse. Once the other objects spawns it will be fused. Now make it so it spawns at the start and in a real game they will be fused.

All you have to do is shoot the Arbiter in the eye and he falls, drops his sword, gets back up, and has another sword. It does not kill him.

Note: Pistol works the best.

Ok, you know how on either side of The Pit there is a room that you cannot normally get to? Well to get there in a real match go to one of the windows with a teammate and jump on top of them. Then, you jump and have them jump right after you so you land on them while they are in the air. Then jump while you are on them and you will be high enough to get into the room. This is great sniping position too.

Have a SMG as secondary weapon and a Spiker as primary weapon. Have the Spike out, pick up a SMG ( DO NOT SWAP THEM ) find another SMG and swap the Spiker With it. Now you have the SMG for a primary and secondary weapon. If you still dual wielding the SMGs and have one as the secondary you will have 3X the ammo of one SMG (which is 580) for reloading. ( the guns are just examples you can use any dual wield gun )

Level: The Ark

Near where you fight the scarab. pick up a grav lift from the small building. Now continue until you reach the 2nd sloping hallway. You will see some platforms halfway down. The skull is on the top level. Toss the grav-lift on the right side of the hall so it lands on the fourth little green dot from the door. Then run, jump, and use the grav-lift to propel you to the top. You should reach a ckeckpoint just as you enter the room so if you miss just try again.

Use the following trick to get a Spartan laser with unlimited ammunition in the "Halo" mission. Play through the level until you meet up with Sergeant Johnson. Shoot him until he falls down and drops the Spartan laser. Quickly pick it up, and shoot it at him. Keep shooting him until he kills you. When you respawn, knock him down again, and pick up his laser. He should get back up with another laser on his back. When he does, shoot him down again, and pick up the new gun he drops. This laser should now have unlimited Spartan ammunition. This makes it easier to destroy the Guilty Spark 343. -From: Camuel

This cheat requires 2 or more people. On any level in forge, one person operates a human turret(not a covenant one) while another person, in moniter form, grabs the turret with the A button. The moniter person can slide the turret along the ground and even fly it around. The person operating the turret can still shoot but cannot rotate the turret, so the moniter will have to do that. This also works in a Warthog passenger seat instead of the turret. Also, if you delete the turret or Warthog while the person is using it, they die. I am surprised nobody has found this yet and posted it.

In Forge on the level "Sandtrap" put a Scorpion Tank in to a elephant and spin it around to make the elephant flip(it is hard). Then go and try to flip the elephant in human form and the strange message will pop up.

wright first of all go on forge note (u will need two people) okay now go on edit mod and were you see that clif were u can see in the back ground spawn a mongoose both of you get on it then get the driver to get of it but keep the passenger on then the other player goes into edit mode and piks up the mongoose but first bring it down to the bit underneath to the side next to the clif so bring it up then medale with it then when the other player is ready jump of and hopefuly make it when you get up there put a spawner there u can always trey it again hope it helps

Right after the Bravo checkpoint in The Ark, you will enter a room with sleeping Grunts. The the far right corner, is a Brute who is taking a piss and moaning with pleasure.

This isn't a cheat, just a easter egg of sorts. In the 2nd level where your in the secret hideout for the humans, if you look around, you will see rats every now and then. Some are alive and just like walk into walls, and some are dead in this frozen, curled up position and roll around. It's kinda funny for a little while, incase your already getting bored of Halo 3.

Ok, you all probably know this one but some of you might not. What you do is you go to forge mode in the map titled "Last Resort." Start the game and then go to the side of the spiney wheel thing closest to the beach. Look at the wheel then turn left the building (you may have to look up a little) that has the shiny window things over the building. Turn into the forge guy and fly right up to the window so that you are touching the glass stuff. Now press "x" and get a Respawn point (make sure it is the only one 2 can be alright but you may have to kill yourself twice. Set it in the building, in other words press "a" and "a" again to create and drop the Respawn Point.
Now you kill yourself (it may take a couple of times if there are more than one Respawn Points). Then once you are inside the only way to get out is dieing if you had more that one respawn points set up, or to start a new round.

Right after you kill the 2 scarabs in the covenant, back up so that the citadel is on the entire screen. look to the left and you will see a shield looking thing (Same on the right). Go to that and on the top you will see a path just wide enough to walk on. take the hornet and hover at almost the top of the slope and get off. Jump to the top and follow the path. You will end up at the top and if the other music has stopped, you will hear a portion of a song called "Halo". It's on the Halo 1 original soundtrack. You can get it on iTunes.

Famine

Effect: Dropped weapons will have very little ammo compared to normal.
Mission: The Ark

When you first go into the valley to the right after the wrecked phantom, look to your left where you will see a very large boulder. Use a ghost and get to the side of the boulder that is closest to the bridge overhead. It is easy to pilot the ghost up the side of the wall using the thrust. To get the skull, pilot 2 ghosts up the wall to the top of the bridge and stack them one on top of another next to the beam where the skull is placed. Simply jump from the top of the ghosts towards the skull and land on the beam.


Iron

Effect: When either player dies in Co-Op on any difficulty both players will restart at last check point.
Mission: Sierra 117

Behind the prison cell where you rescue Sarge is a large ledge. Head to the far right side and jump on the boxes, then onto the pipes to get up on the ledge, goto the far end of the ledge, turning 2 corners the skull is at the far end.

Tough Luck

Effect: Enemies do saving throws
Mission: Tsavo Highway

This skull can be found about halfway through the Tsavo Highway mission. Right after you are forced to walk through a large blue barrier, you will come out of a tunnel on the highway and see a large pipeline on your left. Drop down in between the two, and run to the wall in front. Follow the wall all the way to where it connects with the cliff on your right, and turn to the left. There will be a few ledges so crouch jump from ledge to ledge, and the last one will have the Tough Luck skull on it.


Fog Skull

At the beginning of Floodgate, the first Flood you see that jumps over your head has the skull. Kill it (make sure it's on Legendary) and the skull will fly off of it and land next to you. It's not that hard to kill it; only takes 1 or 2 shots with the Battle Rifle.

Catch
To make the Catch skull appear in the Storm Level, make sure you beat the game on normal or higher, and are playing that level on normal or higher. In the area with the AA Wraith and the normal wraith, there is a small building positioned in the far back. There is no way up. Make sure you kill every ghost,and your team's members who drive the warthog, and stack up viechles . Once on top, if the 2 wraiths are still alive,there will be the catch skull. Grab it and earn your acheivement,soldier!

Mythic

Effect: Every enemy on the field will get double their normal amount of health.
Mission: Halo

As soon as the Halo mission starts walk up the hill in front of you and into the cave. Hug the right side of the cave and after a large boulder you will see a path on your right, just take the short path and it wi
