When you dual wield you are bringing death to your enemies, but the bad thing bout dual wielding is that you can not throw grenades, Melee attack, and reloading takes much longer.
Tactics
If you are in a closed area (small room, hall way, etc.) then hold only 1 weapon, so you can throw grenades. If you are in a open area (big room, outside, forest, etc.) than have 2 weapons in hand because grenades will be useless.
Be The Gunner
Get to a 'Hog and jump in the gunner/passenger seat and let the marines drive. It will be x2 more effective than you driving (it depends on your skill).

Hints
All weapons without an actual zoom have some kind of zoom with no targeting reticle. Shooting pulls you out of it.
The battle rifle shoots 3 rounds at a time The shotgun splash is actually the multiple bullets it sends flying The rocket launcher can lock on on vehicles (or subsystems like on the cov transports) by holding the right trigger down. The brute plasma rifle is a speeded up version of the conventional one but also overheats faster and its red. (i prefer normal version.) The carbine is the covenant equivalent of the battle rifle which shoots one shot at a time. The Brute shot fires grenades which can be compared with frags but with less splash and damage and it has a wicked blade to dish out some pain at a short distance. The needler shoots needle that automatically homes in on target but can be easily avoided at long range but mortal when dual wielding at close to medium range. 7 or more needles in the body creates an explosion that will kill most targets. The covenant sniper rifle can overheat while his human counterpart wont. The fuel rod is a splash machine...better not be to trigger happy in close range with that. The sword is by far my favorite weapon because you can "lock on" in a certain distance and leap for the kill. Someone a high ledge given you trouble? If you can lock onto him hes toast.
Blood Gulch Sniping location
At the Red base, get a Banshee. Get on top and face toward the Blue base. Turn right and go over. Follow the wall up and close to the top. You can get out there and snipe from this location.
Zanzibar: Sword
To get the sword in the middle (if it is on) go to the Ferris wheel-type object in the middle. Line up with one of the blades. Let it push you up the circle until it is parallel with the floor. Then, run forward to the center of the circle. Jump down so that you can see through the center of the 'Ferris wheel'. Wait until a gap appears in the floor, then jump down and forward to the sword.
Fall through floor
On the second level near where the Elites come out of the coffins, there is this support object coming out of the ground. When a Grunt is shooting you, jump on the floor support and you will fall through.
Shoot into space
Shoot the machine gun turret on level one in a phantom tube. Instead of ricocheting, they usually go into space.
Foundation multi-player map
Successfully complete the game in single player mode under the heroic difficulty setting.
Defeating Hunters
Get a beam rifle (the Covenant sniper rifle) and fire it in the middle of their bodies where it is pink. This is more effective then pumping shell after shell into them. Because they have the new gun, getting close to them no longer works. There is another way to defeat them, but it is more costly. First, take your plasma grenades and throw about two or three of them on their pink skinny area. Then, get a shotgun (or the strongest gun you have) and pump the pink spot full of rounds until it is dead. Since they usually appear in pairs, this can waste a lot of ammunition and grenades.
Defeating the Scarab
Instead of following the Marines, go staight across the bridge. You will find a sniper. Take it, then jump on the Scarab and shoot all the Elites and pilots.
Lock on with rockets
To lock on with rockets, target a person, vehicle, etc., then hold R until it says that it is locked. The red reticle will follow the item. Release R to fire.
Switch grenade types
If you have picked up a frag grenade and a plasma grenade, press Black to change from one to another.
Duel Wielding Tip
When duel wielding, the use of both weapons at once is very effective against the smaller enemies, but for attacking the more dangerous enemies or large numbers it is best to fire one weapon until it is empty and then start with the second. For certain weapons like the Brute Plasma Rifle and SMG the reload time is very close to the time required to empty a clip or overheat. By doing this you can maintain a constant stream of fire and supress many enemies at once.
Extra Ammo with Dual-Wieldable Weapons
First, have 2 dual-wieldable weapons (a Needler and an SMG for example), but don't have them out at the same time. The Needler being the one you want extra ammo with, have the SMG out and find another Needler to dual wield with it. Then, find yet another Needler and trade that with your SMG. You'll have 3 Needlers, and have 3x the ammo.
Hunters
In this game, the hunter weapons shoot a continual blast of plasma for a couple of seconds. To didge them, keep walking to the side and you will not be hit(at least you won't have to worry about getting hurt for standing near the shot like in Halo "1"). Shooting them in their front sides won't work unless they have their arm sheilds down, which doesn't happen once they shoot you. If you are in an inclosed space or small area, get close to them and wait for them to smack you. Before they make contact, sidestep, get behind them, and shoot them in their backs. This usually takes a couple of tries per Hunter. Frags don't do much damage, so they are useless, and plasma 'nades won't do much unless you just want ot piss them off, plus they will track you and you will get hurt by the plasma blast. When you are in a lare area, shoot them in the backs with a sniper or laser beam rifle, that will usually kill them instantly.
Sit Back and Relax
About halfway through the game, covenent rebels will start to rise. This is good, and bad. When you are doing the human levels (playing as Spartan-117), the covenent and covenent rebels will wipe each other, making the levels much easier. So, just find a spot where no one can hit/see you and watch the fight(you can make bets with your friends on who will win) until shooting stops altogether, then enter and blast the remaining hostiles. However, when you are doing the alien levels (playing as the arvitar) this makes the levels much harder to do, because you have two ene,ies. Fortunately, as far as I know so far there are no humans when you play the alien levels, with the exception of the dead human corpses that are taken over by the flood.
Blind Mode
At the beginning of Outskirts jump on top of the light on top of the door with a crouch jump, then jump to the left platform. Turn to your left and go down the long dark corridor and pick up the skull; it will say blind and your screen will flash black for a while. In this mode you can not see your weapon, body, shields, ammo, or radar.
To get rid of this feature use the following method:
1. Turn off your XBOX or Save and Quit.
2. Go to Campaign and select level and choose Cairo Station.
3. Skip the cinematics and then Save and Quit.
4. Go Outskirt and your hud is back.
"Blue Screen of Death" in Zanzibar
In the multiplayer map Zanzibar, there should be a computer on the upper level on the defense side that opens up the main gate into the base. After you activate this, the screen goes blue with the infamous BSOD.
In the level where the scarab is helping because marines control it, get into a banshee. Fly up and land on the enemy phantom, it will shoot up through itself and hit you.
Magic Sword
This code requires two people, on any level. Note that both must be on opposite sides, but the point of this is not to kill your opponent, but rather to help him. Have your Plasma Sword in hand, and have someone jump on top of your head. While targeting them, have them jump on your head, and press X and B as fast as you possibly can, you should follow your friend up as he jumps on you. See how high you can go, or better yet, where. Get in the passenger side of a warthog, and target your friend and pull the right trigger. Have your friend run as far as he or she can to the other side of the level and get out. Once you do, aim where you'd like to fly and take off.
Beat Tautarus easily
When you first start the fight, make sure Tautarus' attention is on another NPC and not you. Grab the energy sword from one of the bodies lying around and wait for his back to face you. When he does, dash behind his back and rapidly tap R, It will hurt him and not allow him to react and attack you. About 30 seconds of this kills him.
Give your squadmates better weapons
Once you have almost used up your sniper rifle, beam rifle, or rocket launcher (with 1 shot left ), trade with your squadmate. Once they have that weapon, they have limitless ammo for it and can help you out immensely with the more powerful weapons. There are two points to note: if you try and trade your weapon back from them, it will still have the same amount of ammo that it had when you gave it to them and the energy sword cannot be traded with human squadmates.
Skip tough Brute battle before the end boss
When you are flying around in the Banshee during the final level when you are giving support to your ally. You can skip directly to the final boss sequence if you are still in the Banshee after te door gets blown open. Fly to the right of the control centre building and aim towards the bottom right and if you fly close enough you should get a white screen indicating that you have started the cutscene. When it's over you will be at the final boss without fighting your way to him.
Envy Mode
On the level "Delta Halo" on Legendary Difficulty, Progress until you reach the area during the "Push through the covenant held ruins" where you have to clear a Landing Zone for the Pelican to drop weapons. You will know you are in the right area when cortana says "they're pouring out of the center building". Anyway that area has Plasma turrets along its borders. A little bit after 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.
Iron Mode
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. Once you grab the Iron Skull, Iron Mode will be activated.
Grunts Birthday Party Mode
In the level Arbiter on Legendary. Once you get to the first banshee section, fly immediately straight down all the way to the bottom of the map. In one of the cracks where the large cylinders connect to the station. There will be a circle of grunts dancing around a skull. When you pick up the skull; it will say Grunt Birthday Party on the screen. Now when you kill a enemy with a projectile weapon, they will blow up like a plasma grenade was stuck to them.
To get rid of this feature use the same method as the blind mode.
Angry Mode
When you are the Master Chief trying to recover the index from the Prophet of Truth on the Covenant Holy City go until you reach the first outdoor area with dirt and vegetation. Take a right as you enter this room and run up to the wall past the gravity lift that leads up to the sniper point. Get on top of the wall by going up the dirt mound on your left. Follow the wall until you reach the floating skull called "Angry".
Assassins Mode
A skull similar to the one that activates blind mode can be found if you Start on "regret". After the first lift ride (before the first underwater elevator), grenade jump from the front awning of the lift to the ledge in front of you (the one with two turrets).
Grenade jump AGAIN onto the next ledge.
Make your way to the back of the building. On Easy, you'll only find the skull. On Legendary, however, 2 invisible Elites carrying swords just shake their heads wildly, ignoring you completely.
Easy way to beat the Flood
For an easy way to beat the flood, as an Elite turn on your cammo(white button) and then sneak up behind them, and use the strongest human weapon you have, shoot them in the lower back (where the stomach is, because that is where the parasite is) or in the back of the neck, then run like crap and hide becaue you lose invisiblity when you shoot, then do it again. (the sentinal beam works just fine, it just leaves you open longer, so shoot from farther away, very simple. this is time consuming, but it helps when you are playing by your self.
Best Weapons
Here are the best weapons for defeating certain enemies:
Grunts- SMG, Battle Rifle, Dual anything.
Jackals- Covenant Sniper Rifle
Elites- Dual Needler, Energy Sword, Sniper Rifle
Brutes- Energy Sword, Sniper Rifle
Prophet dudes- Anything you can use.
Humans- Energy Sword, Rapid Firing guns
Sentinals- Sentinal Beam
Giant Robots- Dual Needler, Sentinal Beam, Rocket Launcher
Flood- Energy Sword = One hit kill
Vehicles
Here is a list of the vehicles that you can jack, how you do it, and what it does.
Ghost-Hold x from front of the vehicle (when an enemy is in it) and you will jump on the wing of it the swing kick the pilot out. Hold x from the back and you will punch the pilot out.
Banshee-Hold x and you will kick the pilot out. NOTE: on some levels during the campaign you must be in the back and some levels you are not allowed to steal them, for example the level when you must kill the Prophet of Truth.
Wraith-Hold x from the back and then continue to press b multiple times until the gun shuts down and the wraith stops hovering. Hop out, go to the front of the vehicle, hold x, then you will be able to drive it. Hold x from the front and then keep pressing b to smash the cockpit door until the pilot falls out. Hop off then hop back on to drive. NOTE: You will be prompted to plant a grnade, don't di it it is a waste.
Warthog (multiplier only)-Hold x from the side to throw the pilot out of his seat then you will hop off, hop back on to drive.
Scorpion-I'm not sure if you can take this because I haven't tried, but if you can it can only be done in multiplayer and will probably be similar to the wraith.
Spectre-Hold x from front or side to kick pilot out.
Destroy the Ghost
Facing the Ghost from behind, to the left, behind the left wing is an alien gas tank shaped like a circle. It's only on the left side. Shoot it 3 times with pistol or 1 time with the shotgun and say good bye to it.
Sargeant Johnson
On the level right after the Cairo Station, Sargeant Johnson is invincible. He is the black dude with the sniper rifle, the one that says "Fear humanity, we regret being alien batards, we regret..." and so on. You can use this to your advantage, let him do all of the work. Unfortunately, he eventually boards the pelican almost right after you kill the pair of hunters. Oh, use the turret on the building to kill the hunters very quickly, unless you are playing legendary in which case they will probably blow it up.
Beat the part of the great journey easy
When the marine steals the scareb and breaks down the door to get in do not get out of your banshee. Go through the door with it and then fly straight up.Then go level again. As soon as you hit the wall go down and you should see a door. Get out to open the door then get back in your banshee. You should be in the room where the honor guard brutes come out. use the fuel rod cannon on them a couple times. Fly through the door where they come out and a movie will play. When it start turn around and go back to where you flew in and your banshee should be there. Kill the brute. (Hint do not fly all the way down or you will die.)
Infinite Skull
Difficulty: Legendary
Level: Quarantine Zone
Word: Sputnik
Effect: Lower gravity
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.
Brute Shot Melee
When you're out of ammo, and theres no gun in site, see if you have an empty brute shot on you. Just pick a target, run up to them, and bash them with it! The Brute Shot is equipped with a blade on the back, so it adds a nice damage bonus.
The Brute Shot: Because sometimes "Shoot to Kill" just isn't enough.
Sniper Rifle
Unlike Halo 1, the human sniper does not allow night vision to be used, instead there is an indicator as to how many rounds you have left in the clip. This is diplayed as bullet figures on the right side of the zoom circle. Also when you do not have the zoom on, you can see through the lense on the rifle and it will show a small version of what is ahead of you. This does not help you in any way it just shows the detail that the game designers put into this game.
Needlers
In Halo 1, you are required to empty an entire clip into the enemy in order for them to explode from the missles. In this game, you only need to empty about 1/3 to 1/4 of a clip for the needles to blow your enemy up. This is even more effective when you dual-wield them. Also, on the first couple of missions at least that you have to do as the Arbiter, most of the enemy grunts carry needlers, making this weapon even easier to use.
Rocket Launcher
In the multiplayer games (not cooperation) the rocket launcher is probably the best weapon to use. It will only take one hit to kill, it can lock on if they are in a vehicle or using a turret by holding the right trigger and then releasing it, and it gives no time for retaliation. Of course, there is still a catch. If your opponent is far away and not in a vehicle, it is just about useless unless you can calculate how far they will go and how fast the rockets travel. Also, you only get two rounds per clip, so if you miss twice then you are wide open for a good five seconds or so which is just enough time for someone to kill you. However, there is an additional good side to the rocket launcher, you don't have to hit your opponent directly. As long as you hit the ground or something right, emphises on right, next to them, they will still die. Also, if you hit a little bit away from them, depending on how far away from them, it will still take out little to all of their shields, in which case you can pull out just about any other gun and kill them in few to one hit(s).
Shotgun
The shotgun in this game is very powerful. You can easily kill most enemies, except the final brute, with just one shot. However, there is a catch, you must be at point blank range for it to work (basically nose-to-nose with your enemy). The shotgun is generally just blown off by most people, but as the game gets harder you will find it extremely useful. You might say that getting that close to the enemy risks dying on the harder difficulty levels, but if you get at the right range for just long enough, shoot quickly enough, and wait for your sheild to recharge then you can take out a load of elites with little trouble.
