I am Legendary - How to complete Campaign on Legendary solo!

Contrary to popular belief and myth, conquering Halo 3 on Legendary solo is not impossible…I speak from personal experience.

Covenant

The Covenant present the one of the most challenging aspect of your Campaign woes. However, there is a simple solution to conquering the Covenant on any difficulty setting – pack mentality. Pack mentality is as much present in the Covenant as in the animal world. If you can take out the pack leader, the remaining pack are easy pickings. While the Covenant has a vast host of alien membership, you will typically find a similar assembled group on Legendary: 1 gold brute, 2-3 blue brutes, 2 jackals, and 4-6 grunts.

In order to destroy the pack strength, it is wise to take down the gold brute first, then followed by the blue brutes (who usually go berserk at this point). Once the Brutes are taken down, the Grunts tend to light up their plasma grenades kamikaze style, while the Jackals retreat together in an effort to form a phalanx with their energy shields and carbines. Caution of suicidal Grunts and expert marksmanship for the Jackals are needed to prevent unnecessary death.

Flood

The Flood present more of an annoyance at times, there are certain types of Flood that are the most challenging foe in Halo 3. Although the Flood have no pack mentality, it is wise to follow an order to execution for the Flood.

Classes/Types

Since Halo and Halo 2, the Flood has evolved and changes their appearance and forms. Some types of Flood are more deadly and intelligent than others. While some forms require total destruction, others can be simply avoided by passing by unnoticed.

Flood Stalker/Ranged Form have spike shooter are the most deadly and difficult foe that you will encounter. In order to permanently take these things down, a mid/long range weapon, and a conservative use of plasma and fire bomb grenades is critical to survival. Steady use of a BR or Carbine will provide the necessary fire power to take out this *Flood form (This from will “close up” as a defensive action and during this state it is a waste of ammo if you continue firing –simply wait for the Stalker Flood form to reopen and then continue firing). Another sure method of destruction is to stick the form with a plasma or fire bomb, which requires steady aim and precision.

Pure Tank Form Flood are the massive bull dozers that transform into the crawling spike shooters. In order to make life easier, it is wise to take these forms down with a plasma or fire bomb, sword, or needler. The only caution needed for the *Flood form is to avoid direct contact from their devastating and deadly blows.

Elite Flood present another challenge due to the fact that they are difficult to kill with most weapons. The best method of destruction is either a needler, sword, plasma of fire bomb grenade.

Brute and Combat Flood are the easiest form of Flood to destroy because they are easy to melee and take down with any weapon of choice. If the situation allows, it is best to pass by these forms unnoticed.

Flood carriers and bubble flood are easy to with any weapon of choice, and they present more of an annoyance than a real challenge. If the situation allows, it is best to pass by these forms unnoticed.

Chieftains

The Brute Chieftain can be the hardest and yet the easiest challenge of Halo 3. If the Campaign missions allows, conserve the Spartan Laser for the Chieftain, while remembering pack mentality. Take down the Chieftain first with one Laser shot, and the pack will crumble (should you fail to kill the Chieftain with two Laser shots, either kill yourself or allow yourself to be killed in order to reload at the last saved check point). For the other Campaign missions that do not provide a Spartan Laser, simply conserve any power (plasma cannon or fuel rod gun) or long range weapon (sniper or BR) for the Chieftain.

Do not try to stick a Chieftain with a plasma or Brute spike grenade, since the Chieftain’s shields will simply deflect the grenade or he will dodge out of the way. Some tools of destruction that are useful include frag grenades, power drains, needler, fully charged plasma pistol blast, or a fire bomb grenade.

Jackal Snipers

Considering how physically small these members of the Covenant may appear, their presence is huge! It has been said these the Jackal sniper is so talented that he is able to snipe a flea off a dog’s back, and once you encounter a Jackal with a beam riffle, you will agree. Somewhat remembering pack mentality, it is wise to kill any and all snipers before or shortly after killing the Brute leadership. Once the Jackal sniper is down, you can move freely and clean up the remaining Covenant ranks.

Hunters

While deadly, the Hunters are rarely seen in Campaign. In order to preserve your companion’s lives, simply use the Spartan Laser or any many plasma and Brute spike grenades required to take down these monsters.

Companions

Although few and far in between, the companions that fight with you can either make or break your Legendary efforts. Whether UNSC or Covenant, it is best to arm your companions with the appropriate weapons for the mission at hand - it is wise to consider the mission ahead: enemies, vehicles, and required weaponry to take out the enemy. Another tip it to allow your companions the freedom to advance ahead of you so that: they may take down as many enemies as possible, die with their weapons and grenades that you equipped them with, and provide the necessary distraction needed for you to pick off any pack leaders.

Weapons

The right combo can make or break your Legendary efforts. The best combo is a long/mid range and short range weapon. If you are a skilled marksman, a sniper and mid range combo is best option to play the game smoothly; grenades are in abundance (depending on the mission), so make use of this valuable tool of destruction.

Mission Knowledge – Sniper spots

Simple knowledge of where sniper, beam riffles, BR, and Carbine weapons are located is essential to survival. There are some missions where these select weapons are located, and expect marksmanship and pack mentality and the key secrets to Legendary solo.

Mission Knowledge – Heavy weaponry

Simple knowledge of where shotguns, rockets, fuel rod guns, missile pods, and vehicles are located is essential to survival. Depending upon the mission, you will want to conserve certain weapons for later use.

Mission Knowledge – Reactions

Playing the game numerous times will eventually increase your knowledge on Campaign game play. Much like clockwork, the enemy will be in the same place, at the same time, with the same weapons, and usually repeat the same actions. Continuous repetition will train you to expect and predict at least 3-10 seconds, so use your knowledge wisely to take out the pack leadership and secure the ideal weapons and secured spot in the mission.

Loading Points

Knowledge of loading points is essential to completing the Campaign missions with less frustration and effort. It is recommended that the game be played on Normal in order to get a feel and knowledge of Campaign loading points. Making every effort to reach a loading point, (no matter what your health or weapon situation) will allow you to reload past all that mess you have just left behind.

Multiplayer
Complete Online Achievement Guide

Legendary 125 Finish the Campaign on Legendary - (unlocks achievement for Normal and Heroic, if not earned).

Marathon Man 40 Locate and access all Terminals in the Campaign.

The Ark

In the first building on the level, you will see a door almost immediately on the left across from a purple holographic panel. Simply enter this area of the level to find the first of the seven terminals.

When you go inside the structure to let the tanks across the bridge of light, there will be a Terminal almost directly behind the controls for the bridge. You must activate the bridge before you can access this terminal.

There is a part in the level in which you walk down a long hallway with white walls, and turn to the left at the end to continue. In the next room there will be a grunt wandering around, and many stacked up plasma batteries. As soon as you enter this room, go underneath the staircase on which you are standing. Underneath there will be a door that conceals the terminal.

The Covenant

The fourth Terminal is located near the first elevator control. Before you ride the elevator up to find the Terminal start by looking at the access button. Next, look directly to the left you will see a dark ledge. Jump across to that, continue walking forward and the Terminal will open up.

After getting a Hornet vehicle, fly towards tower 2 (the one that the Elites had already disabled). A voice will remind you that Tower 2 is already clear, just to confirm you are at the right place. The Terminal is in the main hallway of the structure, across from the only door.

Terminal 6 is identical to Terminal 4, only in the 3rd tower and off to the right (versus the left in Terminal 4).

Halo

Terminal 7 is found at the beginning of the final level in Halo 3. To find it, head forward from the start of the level until you encounter the area with a few structural beams going from one wall into another. At this point, turn right, and look for a beam separate from the rest. Follow this beam into a doorway. Cortana will ask you, “Where are you going?”. Turn left once inside, and the Terminal should be in full view. Cortana will say "Wait. What's that?" as a good hinter. The terminal will be in front of one of Installation 04's believed pulse generators.

We're in for Some Chop 5

Destroy an enemy vehicle with equipment in a ranked playlist or in campaign. One way to get this achievement is to start Tsavo Highway second loading point, keep a fuel rod gun and wait for the Brute choppers to come after you destroy the Wraith. You may have to kill all of the UNSC troops first as they tend to get a little greedy and destroy the choopers before you do. When the first chooper charges you, blast it 2-3 times with the fuel rod gun, and throw down a trip mine located where the UNSC troops were taking cover from the Brutes. Can be done on Normal.

Used Car Salesman 5

Destroy a vehicle that has three enemies in it in a ranked playlist or in campaign. In the hanger of Crow's Nest two Phantoms come inside the hanger, three if playing on Heroic and Legendary. You can also wait until after Forward Unto Dawn drops off the three Scorpions and the Gauss Warthog. There are multiple opportunities where a Phantom is stationary and in range. Using the Scorpian's primary weapon, roughly 5-7 direct hits will shoot it down.

Skulls 10 each for total of 90

Find and grab each skull by pressing the right bumper (default controller settings), once you hold it for a few seconds, the achievement message will pop up and you can drop it by pressing to switch weapons or throw a gernade.

Gold Skulls:

Iron - If you die while playing solo, you will restart at the beginning of the level (you cannot revert to the last checkpoint at any time). If any player dies while playing co-operative, you will reset to the last checkpoint.

Black Eye - Your Energy Shield will not recharge until you perform a melee hit. The Energy Sword and Gravity Hammer's R-Trigger attacks count as a melee attack. Hijacking also counts as a melee attack.

Tough Luck - Enemies dodge grenades, needles, and vehicle assaults with a far greater success rate. However, plasma and spike grenade sticks are still possible at close range, and from behind.

Catch - All AI-controlled units, friend or foe, throw grenades more often, where applicable. The Catch skull has no effect on Flood, as they don't throw grenades. It should be noted that they will throw a unlimited amount of grenades at their enemies. Grunts have been seen throwing more than 4 in a row. The skull does not seem to increase the number of Kamikaze Grunts, however.

Fog - Your motion sensor is no longer visible.

Thunderstorm- All enemies (and Sangheili allies) are promoted to the next available rank. The number of shielded Flood combat forms is also increased. Elites that would have been Majors do not become Ultras, however, and stay the same rank. Basically, field promotions for everyone!

Famine - All weapons that are dropped by enemies or are scripted to spawn on the ground (e.g., near a downed Pelican or group of dead bodies) have halved or reduced ammunition or charge. However, weapons found in cases still have the regular amount of ammo.

Tilt - All energy shields (including Brutes' and excluding the Master Chief's) are made a lot stronger. Human projectile weapons cannot take down Brute Shields.

Mythic - All of the Covenant you encounter have twice the amount of health.
