Hint: Defeating Elites-[Halo 2 ] When battling with Elites, do not hit them once with your weapon. Always hit them multiple times. If you hit them once, they will have a faster time and kill you with one hit or take down your shield. Information in this section was contributed by Game_Freak15. An easier way to kill Elites quickly is to double-wield the SMGs and aim for the head. Be careful, as the SMGs tend to send the reticle upward. Also, try meleeing him before using the double strategy.
Hint: Using a destroyed machine gun You can use a destroyed machine gun; for example, in Zanzibar after you fire a rocket to one of the turrets on the left and right on the main base. Just go back to them and the screen will prompt you to hold X to operate. This can be useful during heated sessions.
Hint: Defeating Prophets To kill Prophets, you must dodge there laser attacks and get up close until the message to hold X to board appears. Do so. Once onboard, tap B to attack them. Three hits should kill them. If not, repeat until it falls.
Hint: 2 on 2 on 2 on 2 on 2 on 2 on 2 on 2 Make a new Slayer game, and set the active players to two. Leave most selections at default, except turn off active camo and overshield. Set the starting weapons to the battle rifle and the shotgun. Turn off all vehicles except for two Warthogs, and turn off gun emplacements. Turn on teamplay, and turn off team switching. Set the betrayal penalty to 5 seconds. Play at Coagulation. This should allow you to have eight teams of two people each, making for some really fun teamwork games. If it does not, play with the active players setting until it works.
Hint: At ease position *Halo 2* While in a multi-player game, press D-pad Down. To other players, you will have your weapon lowered or down to your side. This may help if you are on your own turf and run into one of your friends right around the corner.
Hint: Blood Gulch: Sniping location(Halo 2) 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.
Glitch: Extra ammunition with dual wield weapons Have two dual-wieldable weapons (for example, a Needler and an SMG), but do not have them out at the same time. The Needler would be the weapon that you want extra ammunition for. 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 will now have three Needlers, and have three times the ammunition.
Hint: Howard Dean scream(Halo 2) At some point in the game when you are playing as Master Chief, one of you allies will do the Howard Dean scream while they are attacking.
Hint: Blood Gulch reference Go to multi-player mode and scroll to the Coagulation map. Read the description. It will describe "a bloody gulch".
Hint: Defeating Brutes Get a Plasma Sword from a dead Covenant Elite and get close enough to the Brute for the half-circle surrounding the crosshairs to turn red before attacking. You will lunge forward and get rid of half the enemy's life. Jump into the air immediately afterwards, and do this a second time to kill him instantly. Both attacks combined cost only ten ammo points, so this process can be done ten times in succession, making it an effective way to crowd-clear Brute patrols near the end of the game. Make sure to jump in-between each strike so that the Brutes you are fighting cannot continue to ram you and drain your life.
On the last level when you are fighting the head Brute, wait for his shields to go off (when the blue gas-like thing around him shuts off). Then, shoot him in the head as many times as you can until it turns back on. Repeat this process until he is dead. Do not use an energy sword. It will not work, and he can kill you with one hit of his hammer.
On the final level, once you reach the door that leads to the final battle, a group of Brutes will come out. Instead of fighting them, use your invisibility gear and sneak through the door without having to fight. Note: You must be fast or the door will lock.
When you are facing several Brutes together, such as in the Uprising level, use a weapon with good accuracy, such as the pistol. However, this may be difficult because it no longer has a scope on it. The Covenant Carbine is a good choice because it has great accuracy, a zoom, and a usable clip size. When using the carbine, aim for the skull plating they have on the top of their head. If you are a skilled shot, this should kill the Brute in about four to five shots. Have something like the energy sword as a backup in case there are too many and they charge.
Hint: Unlimited ammunition or power(Halo 2) This trick requires levels that have either Covenant or Marines following you. If you have a powerful weapon that has very limited power (for example, the energy sword, or Covenant sniper), or weapons that are very powerful (for example, Human sniper or rocket launcher) give them to the A.I. following you. As they use them, the weapons will never run out of power or ammunition. Also, they can use them very well.
Foundation multi-player map Complete the game in single player mode under the heroic difficulty setting.
Hint: Outskirts: Blind mode When you begin the mission, your vision will get blurry. When it returns to normal, you will see a blinking door. Enter it, then stop. Look up to see a fluorescent light over the door you just used, and another one on the opposite wall. Jump and duck at the same time to get on one of thos lights. Do the same thing again to get onto the ledge next to the lights. Look to the left on the ledge and you should find a dark passage. Follow it to find some grenades, a skull, and a camera at the end. Take the skull and your HUD will disappear and the word "Blind" will be displayed. You will not be able to see your weapon, body, shields, ammo, or HUD. You can use the skull as a melee weapon, which does good damage to opponents. However, using a grenade, firing a weapon, trying to drive, or using a turret will drop the skull. However, you can be a passenger in a Warthog and still keep it. To return to normal vision, save and quit the game, select the Cairo Station mission in campaign mode, save and quit the game, then return to the Outskirts level.
Hint: Defeating Royal Guards To easily take down Royal Guards (red Elites with strange helms), attack them with the energy sword. Do not be afraid -- keep slashing. They will fall after about three hits. Note: If it has a energy sword, you must get the first hit or it can kill you with one shot.
Hint: Have the same primary and secondary weapon while not dual wielding This trick can only be applied to weapons that can be dual wielded. For this trick to work, you need four dual wielding weapons in one place. Two or three weapons of the total four weapons must be the same, but remember a minimum of two of same weapon is necessary in order to have same weapon for both primary and secondary slot. For example, have two needlers, an SMG and a plasma rifle. To get two needlers, carry one needler as your primary weapon then select anything else but the needler (such as the SMG gun) as your secondary weapon. Note: You cannot select the same weapon as your secondary any way. Dual wield plasma rifle with the SMG then go to the needler that is on the ground, hold X, and substitute the second needler with the SMG gun. Then, throw the plasma rifle away by pressing B. You are left with the Needler as both your primary and secondary weapon.
Hint: Snipe from vehicle Piggyback on a Banshee. Before one member of your team gets into the Banshee, jump on top of the Banshee's pilot cover. When you get in, you can just stand on top of it. Only make turns with the Right Analog-stick. They are slower and do not tilt the Banshee. More than one player can stay on top of the Banshee. This provides extra fun if you want to do aerial tricks with friends by jumping from Banshee to Banshee.
Glitch: Shoot into space Shoot the machine gun turret on level one in a phantom tube. Instead of ricocheting, they usually go into space.
Hint: Stealing vehicles When playing a multi-player map with vehicles, you can steal vehicles such as the Wraith from your opponent. Approach the vehicle while holding X. Note: This removes your opponent from the vehicle only; you must press X a second time to board the vehicle.
To hijack a Wraith, you must get up close to it by first destroying the side guns. You will get a message to press X. Do so, and you will be hanging on the side of it. Then, tap B to punch the door in. Next, press L and throw a grenade in. Jump off and go back in by pressing X, and you will now be driving the Wraith.
Use the following trick to knock enemies out of vehicle safely. Note: This only works with a fast moving, non-flying vehicle. First, stand by a wall or something that they can crash into. Try to get the opponent to run you over, then jump out of the way after about a second of contact. He should then crash into the wall. When he does, go directly next to it and hold X. You should now be in the vehicle.
Hint: Zanzibar: Sword -Halo 2 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.
Hint: Jump faster Keep pressing Jump to jump faster.
Hint: Flying sword Have the sword when an enemy is very close. You can jump and do it, or run and jump to them, then press B. This is a one hit kill for Flood, and a two hit kill for some Covenant and the shield Flood.
Glitch: 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.
Hint: Piggyback ride on vehicle With almost any vehicle, you can get a piggyback if you are not skilled at driving or need a fast ride when someone on your team is already on a Ghost. This also works with the Scorpion, Banshee, and the Warthog when you have someone in the gunner seat, when you are all far enough away from the enemy.
Hint: Active camouflage When in campaign mode as alien, press White to turn on the active camouflage. Note: It does not last long.
Hint: Banshee tricks When in a Banshee, press A and a direction on the Left Analog-stick.
When in a Banshee, hold A and press Left Analog-stick Down. The Banshee will do a backflip.
To do tricks in a Banshee, press Left or Right on the Left Analog-stick and hold A to do a barrel roll, or hold Down + A to do a loop.
Hint: 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.
Hint: Change splitscreen orientation To change the screen orientation in a cooperative game from horizontal to vertical, enter the Xbox console settings and change the video to widescreen. On a regular display, this will change the splitscreen from horizontal to vertical.
Hint: Defeating hijackers Use the following trick in multi-player mode with someone that is trying to steal your vehicle. When you definitely know that they are trying to board your vehicle, press X to hop out as they board. This will give you about three or four seconds to blast them before they can get a bead on you. This requires some skill, but works very well. It is possible to take out a Banshee, Ghost, and Warthog with one SMG by doing this.
Hint: 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.
Hint: 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.
Hint: Defeating Floods Get a Plasma Sword from a dead Covenant Elite and get close enough to the Flood for the half-circle surrounding the crosshairs to turn red before attacking. You will lunge forward and kill the enemy instantly, sometimes killing two or even three if they are in close-enough proximity to the target. This attack only uses between two to five ammo points, so it can be repeated at least twenty times. Note: Do not use this trick on either the small spider-like Flood or the large bulbous Flood, as the explosion that follows will damage your shields.
To kill the Flood, easily use the sword. It cuts right through the Flood in one shot, unlike any type of plasma gun.
Hint: Defeating Regret *Halo 2* To easily defeat the prophet Regret, jump on his vehicle then hold X to board it. You can then press B to melee him to death.
Hint: Switch grenade types If you have picked up a frag grenade and a plasma grenade, press Black to change from one to another.
Hint: Dual wielding recommendations when dual wielding, it is best to think about things before you just grab a needler and a plasma pistol, and have a pistol as your third weapon. You should make it so you have a good backup weapon; when dual wielding, ammunition can go quite quickly. Have two plasma rifles (or your choice) and have something like a particle beam rifle, shotgun, Covenant carbine, or perhaps a rocket launcher so that you have something to fall back on. Some suggestions are as follows: Needler x2 Plasma rifles x2 SMG x2 SMG and a plasma rifle SMG and a plasma pistol Note: Having two plasma pistols is not a good choice because you cannot hold the two triggers down, or you will power them up. You must keep pulling, making this somewhat difficult.
When wielding two weapons at once, use only one at a time, and when that runs out of ammunition, use the other one while reloading. Do this to keep up a steady stream of fire.
