Legendary is the highest and most difficult setting of Campaign gameplay in every Halo games to date, aside from the informal "Mythic" difficulty which is Legendary with all Skulls active in Halo games that feature them. The Legendary difficulty is also featured in Firefight, Skirmish, and Spartan Ops games.

Summary

The original Legendary shield.

In the original Halo trilogy, legendary difficulty is symbolized by an Elite skull with a bullet-hole through one side, two crossed combat knives and a shield bearing the Marathon symbol, though the symbol is not visible behind the skull. In Halo 3: ODST, the symbol is adjusted to a human skull with two crossed Suppressed SMGs in front of the same shield with the Marathon symbol, now slightly visible behind the skull. In Halo: Reach and Halo: Combat Evolved Anniversary, the original legendary symbol returns, but these games, along with future titles, lack the Marathon symbol on the shield. In Halo 4, the shield and the combat knives have been redesigned while the skull of a Promethean Knight replaces the previous skulls.

Legendary is regarded as a significant challenge, even for veteran players. Overwhelming enemy firepower, superior enemy numbers, and increased enemy intelligence make up most of the challenge, but several specific changes, varying throughout games, also add to the difficulty. Most allies are practically useless aside from creating distractions. The player must play cautiously and conservatively to succeed, but even with appropriate tactics and practice, the player will die very often and may require some luck to succeed. The increased difficulty does not come without rewards; many details, such as pieces of dialogue, cutscenes, and music, can only be heard or seen on Legendary; in particular, most Halo games feature an additional scene in the ending cutscenes, which is only shown on Legendary, often referred to as "Legendary Endings". Halo: Combat Evolved, Halo 3, Halo 3: ODST, Halo: Reach, Halo 4, and Halo 5: Guardians feature such endings. Several achievements, challenges, commendations, and career awards reward players for accomplishing various tasks on Legendary difficulty in addition to the achievements for simply completing every mission on Legendary.

Halo: Combat Evolved and Halo: Anniversary

In the first Halo game, the differences between Legendary and other settings is relatively numeric. The player does not face unique or different enemies yet they face many more enemies who are tougher to defeat and endure. Many of the same strategies that work on other settings work on Legendary in this game except that the player has to be extremely careful of his/her own weaknesses. This is where the Noob combo comes in handy, with use of the Plasma Pistol and M6D Magnum.

General differences

Player shields are half their Normal resistance. A few hits from plasma will often drain them completely.
Enemy shield resistance is strengthened.
Extremely weak health. One melee from an enemy in front of the player will often prove fatal.
Player shields and enemy shields recharge faster - twice as fast as when on Normal difficulty.
Enemy health is doubled.
Sangheili: Twice as many Sangheili appear as on the Normal difficulty. Sangheili Major are encountered at a ratio of about one of every three Elites encountered, improving enemy forces. An area that had two Sangheili Minor on Normal should have four to five Elites on Legendary with one or two of them being Majors. Their shields can take 28 rounds from an Assault Rifle before lowering.
Unggoy: Twice as many Unggoy appear than on the Normal setting. Around half of the Grunts encountered are Unggoy Major.
Enemy Grunts and Elites throw grenades frequently, much faster and almost always accurately. The grenade detonation timers are cut in half.
Firing Rate : All enemies fire their weapons much faster and more accurately. In particular, Kig-Yar will fire long streams of 10-15 shots with high accuracy. Kig-Yar will also charge their plasma pistols much more often proving deadly in combat.
Agility : All enemies move much faster and will rarely allow a player to stick them with grenades. Sangheili will often do their dodging maneuver immediately if hit, making it very difficult to make consistent hits on them to drain their shields.
Stealth Sangheili: They are always encountered in packs of four to six with few exceptions.
Flood: The Flood are now armed 90 percent of the time. Their deadly melee attacks will drain shields by half. Many more of them wield Shotguns and Rocket Launchers than before. Only a couple of Infection Forms can completely drain your shields, and an explosion from a Carrier Form can kill you instantly if your shields are completely or partially drained.
Allies: Marines are virtually useless. They will constantly get stuck with grenades and most are easily killed by the enemy's increased rate of fire. Their returning fire only inflicts minimal damage on enemies. Their AI is increased significantly, still to little effect.
Sangheili Zealots appear more frequently throughout the game. Incredibly, it takes 21 shots from an M6D Pistol to remove their shields alone.

Specific differences

The Pillar of Autumn:
- The player does not go through the controls section at the beginning of the level, the game assuming that anyone choosing the highest difficulty level has gone through it before. Instead, they will wake up and leave the cryo section immediately. This also occurs on Heroic difficulty.
- Johnson's speech changes in the beginning of the level.
- The player has immediate access to the motion tracker and Frag grenades.
The Truth and Reconciliation:
- Upon entering the loading bay, 4-6 Elite Zealots will ambush the player and the Marines in addition to the standard waves of Grunts and Jackals which pass through the hallways. There will also be a couple of Hunters.
343 Guilty Spark:
- The shotgun is no longer available early on in the game. The only way to pick it up is to kill a Flood combat form that was holding one or from one of the dead Marines from the third room with an energy bridge.
The Maw:
- The player only has five minutes to get to the Longsword fighter after destroying the Pillar of Autumn's engine core as opposed to the usual six minutes.
- The player will get to see the non-canon secret ending.

Halo 2

In one of the Bungie Updates, Frank O'Connor describes Halo 2's Legendary as:

“

A whole new sick twist on game difficulty. Legendary includes bizarre stuff like perma-death for Co-Op players, meaning that you can't hopscotch like you can on other difficulty levels. Once a player dies on Legendary, both players are hurled back to the last checkpoint. It's brutal. Also, that place where you encountered two grunts and a flowerpot on Normal? Well now they're hunters, high-ranking, Sword carrying Elites and they're all PMS-ing. Seriously, sticking your head around a corner on level two can get it shot clean off.

”

General differences

Both players have "linked lives". That is, when one of the players dies, both are sent back to the last checkpoint regardless of whether or not only one of them died (Possibly to prevent players from easily reaching the status of beating Legendary on their profile or to enhance it with the general knowledge of the above statement). This effect is similar to enabling the Iron Skull.
Enemy fire or munitions have a faster velocity.
Enemies will tend to use more powerful weapons earlier in the game or more often, such as Ultras and Zealots with Energy Swords, Unggoy with Fuel Rod Guns and Needlers, and finally Jiralhanae with Brute Shots.
Flood Combat Forms will frequently wield Shotguns and Rocket Launchers. A shot from a Shotgun at mid-range can kill you instantly. There are more Infection Forms present, and they will instantly revive any Combat Form if their corpses are intact.
Enemies will tend to stick together, and not follow the player too far from their spawn point, making it very difficult to ambush them.
Enemies will throw grenades more often, and if the player is behind cover they may continuously throw grenades until the player moves or is killed.
One burst from the Plasma Rifle is enough to kill the player (Four to penetrate shields and three to kill).
Enemies fire at a much faster rate and fire extremely accurately.
Enemy numbers are drastically increased.
Shields are 50% their Normal resistance and a few hits will drain them completely.
The Arbiter's active camouflage lasts only five seconds and takes ten seconds to recharge.
Enemy shields and health are almost double their Normal resistance.
Virtually all Sangheili encountered are Majors. Unggoy Majors are also far more common.
Elite Ultras are now a very common sight. The player will encounter up to four in some parts of the game. They have the most powerful energy shields in the game and can survive four head shots from a Sniper Rifle or a Beam Rifle.
When playing as the Master Chief, the player has to face large numbers of Elite Zealots. They always wield Swords and can slaughter large groups of Marines with ease.
Enemies are extremely adaptive and intelligent in tactical action. They rarely fall victim to being outsmarted.
Grunts retreat less often when a leader is killed.
Marine allies are much stronger. They have more health and their AI is increased significantly. They are still highly vulnerable though.
- Marines can withstand one shot from a sniper jackal without dying.
Melee attacks received from Elites and Flood combat forms are practically always one hit fatalities, however moving to the side will reduce the damage concurred from such attacks.
- Melee attacks from Heretic Elites are glitched, so the player will not take any damage from them. This can be used as a saving grace in otherwise bad situations. This does not apply when a Heretic Elite is holding an Energy Sword.
Enemies normally have upgraded weapons. For example, Brutes that usually had Brute Plasma Rifles would now carry Carbines or have the deadly Brute Shot equipped.
Enemies will often notice the player sooner and prove to be more alert.
Kig-Yar Snipers will appear more often than on any other difficulty. They can kill the player with only one shot regardless of where it hits. Players should think twice before sticking themselves out into the open.
Stealth Elites appear more often and travel in groups of two to four, usually with one or two dual-wielding Plasma Rifles and the others using Energy Swords.
Almost all Elite Combat Forms have shields.
One shot from a Brute Shot will have the same power as a shot of the rocket launcher on Easy difficulty.

Halo 3 and Halo 3: ODST

The Halo 3: ODST Legendary shield.

General differences

Shields are 50% their Normal power and a few hits even from a Plasma Pistol will drain them completely.
Enemies are much more resistant to damage. (E.g. The player needs three body shots or two headshots for a fully shielded Brute Captain to take it down instead of one headshot or two body shots with a sniper or beam rifle).
Headshots are the only means to get a quick kill on enemies like Jackals and Grunts, aside from assassinations.
Nearly all enemy forces are promoted by one rank. This can be changed with the effects of the Thunderstorm Skull, which promotes enemies even higher. In addition to this promotion, Brutes will not carry deployable covers.
Enemy numbers double or sometimes triple in the case of Flood encounters.
Enemy AI improves dramatically, enemy vehicles will be significantly harder to hijack and enemies will be nearly impossible to stick with grenades.
Jackal Snipers, one of the rarer enemies in Halo 3, will appear with greater frequency, though not nearly as much as in Halo 2.
Enemies fire much faster and more accurately, and toss grenades more often and with greater accuracy.
Turrets, such as Shades, are frequently encountered, even in places in which they did not appear in lower difficulties. Gunners will also fire more aggressively.
Brutes will wield Brute Shots more often. They will fire them faster and more accurately. They will also frequently go berserk.
The "linked lives" system from Halo 2 is removed but can be achieved with the Iron Skull activated.
Almost all Sentinels have shields, including allied ones.
In single-player mode, the Arbiter is next to useless and will frequently be knocked out for prolonged periods. He will also take cover a lot more and so reduce his outgoing fire. However, he becomes a powerful ally if wielding an Energy Sword when fighting the Flood, especially in the level Floodgate.

Specific differences
