Transcript

{Cutscene}

The Master Chief flies a Banshee to High Charity. He finds an opening into the hive. (In co-op, Thel 'Vadam will follow the Chief and land his Banshee next to the Spartan's Banshee)

• Sergeant Major Avery Junior Johnson (COM): "Chief, I'll round up our survivors, fall back to the Dawn."

The Chief drops down onto a wide platform from a hole above ('Vadam follows him in co-op)

• Johnson (COM): "Arbiter will do the same with the Elites."

(Co-op Change) Johnson (COM): "The Shipmaster will do the same with the Elites."

The Chief shakes off some organic material that is stuck to his boot.

• Johnson (COM): "Cortana's in there somewhere..."

{Gameplay}

Rampant

Graverobber.

The Chief begins searching, further in the hive.

• Gravemind (Gravemind Moment): "Child of my enemy, why have you come? I offer no forgiveness: a father's sins pass to his son."

The Chief drops down a porta.

• Cortana (Cortana Moment): (A strange mix of cries of agony and psychotic laughter)

• Cortana (coming out of a speaker within a crashed Pelican): "I ran, tried to stay hidden, but there was no escape! He cornered me, wrapped me tight... and brought me close."

As the Chief goes deeper into the hive.

• Gravemind (Gravemind Moment): "Of course, you came for her... We exist together now. Two corpses, in one grave..."

• Cortana: (distant) "A collection of lies; that's all I am! Stolen thoughts and memories!"

• Gravemind (Gravemind Moment): "And yet, perhaps a part of her...remains?" (maniacal laughter, fades into Cortana's voice)

• Cortana: (deranged laughter)

In the large room where the Tilt skull is located, a terminal can be activated, but does not count towards the Marathon Man achievement. If activated, it displays another Cortana Moment.

• Cortana (Terminal): "It was the coin's fault! I wanted to make you strong, keep you safe...(drop in tone) I'm sorry, I can't..."

Cortana begins to show signs of Rampancy.

• Cortana: (casually and kindly, as though nothing is wrong) "May I speak with you, please?... What's your name? It's very nice to meet you!... You like games? So do I."

The Chief struggles through into more narrow, Flood-contaminated tunnels.

• Cortana: (upset and frightened) "I'm just my Mother's shadow... don't look at me, don't listen! I'm not who I used to be..."

As the Chief nears a large room (with the route to the reactor room at the top):

• Gravemind (Gravemind Moment): (angrily) "Time has taught me patience! But basking in new freedom, I will know all that I possess!"

The Chief continues to the reactor room.

• Cortana (Cortana Moment): (panicking, her voice slightly distorted) "I have walked the edge of the abyss. I have seen your future, and I have learned!"

The image of Cortana suddenly turns a tinge of green. She clutches her head and writhes in pain.

• Gravemind (Gravemind Moment): (angrily) "Submit! End her torment and my own!"

The Chief enters the reactor room, passing by bones and skulls back at the entrance.

The Chief finds a door out of the reactor room, and follows it.

• Cortana (Cortana Moment): (panicking, voice slightly distorted) "There will be no more sadness, no more anger, no more envy!" (a reference to the three main stages of rampancy.)

• Gravemind (Gravemind Moment): (enraged) "You will show me what she hides...or I shall feast upon your bones!"

The Chief begins to reach the end of the hallway.

• Cortana (Cortana Moment): (Speaking in a calm, distorted, monotone voice as though brainwashed. Her image is green.) "This is UNSC AI Serial Number CTN 0452-9. I am a monument to all your sins."

The Chief rushes to the end of the hallway, to find Cortana lying prone in a Stasis Field in a center podium. The room resembles the Sanctum of the Hierarchs. He beats and bashes the shield until it finally fails.

{Cutscene}

• Cortana: (weakly) "You found me."

Master Chief leans closer towards the panel Cortana's on. The AI lies pitifully on the podium, pain and shame on her face. The animated code that usually flows across her skin is absent.

• Cortana: (weakly) "But so much of me is wrong... out of place. You might be too late..."

The Chief kneels right next to Cortana.

• Master Chief Petty Officer John-117: "You know me. When I make a promise..."

She looks up at the Chief. Cortana starts to glow.

• Cortana: "You... keep it. (she raises her head, and sounds amused) I do know how to pick 'em."

• John-117: "Lucky me. Do you still have it?"

Cortana slowly gets up.As she does, she begins to glow more brightly, and the lines of code and equations once again begin to fall over her surface. She opens her palm and a hologram of the Index appears above it.

• Cortana: "The Activation Index from the first Halo ring. A little souvenir I hung onto...just in case. (she looks around) Got an escape plan?"

The Chief gets back up on his feet.

• John-117: "Thought I'd try shooting my way out - mix things up a little."

The Chief takes Cortana's old data chip out of his helmet and holds it in front of her. Cortana touches its core and uploads herself into the chip, and the Chief inserts Cortana back, at long last, into his armor.

• Cortana: (jokingly exasperated) "Just keep your head down... There's two of us in here now, remember."

{Gameplay}

Nor Hell A Fury...

Shoot your way out.

If the Chief continues to stay in the room Cortana was in.

• Cortana:(weakly) "Chief, get me out of this place. I... I don't want to stay."

The Chief heads back up the hallway.

• Gravemind (Gravemind Moment): (roars) "Now, at last, I see! Her secret is revealed!"

The Master Chief makes it back into the reactor room.

• Cortana: (weakly) "Wait, we need to buy some time. This reactor... start a chain reaction. Destroy High Charity."

The Flood begin to swarm the reactor room, realizing the Chief's plan. However, he successfully destroys all three reactor pylons.

• Gravemind: (roars in pain)

• Cortana: "You hurt it, Chief. But not for long. We need to get to Halo - destroy the Flood once and for all."

If the Chief takes too long:

• Cortana: "An explosion just made us an exit! I'll mark it on your HUD, Chief, go!"

When the Chief reaches the halfway point escaping:

• Cortana: "Analyzing the route ahead... I have it mostly figured out. Just keep moving, I'll update your HUD as you go."

Cortana: "Corridors ahead have all collapsed. I'll find another way, Chief; be careful."

• Cortana: "There, Chief, into the maintenance tunnel."

The Chief finds his way back when...

• Cortana: "I've got a friendly contact! But who would be crazy enough to come in here?"

Chief and Cortana find The Arbiter battling Flood with a Flamethrower. The Chief assists.

• Cortana: (amused) "Wait, you two made nice? What else have you been up to while I was gone...?"

{Cutscene}

The Master Chief and The Arbiter find a Pelican, possibly from In Amber Clad, nearby and board it. The Chief uploads Cortana into the Pelican's holotank and starts up the engines. One of the Gravemind's tentacles advances to the Dropship, but the heat from the thrust forces it to retreat. The Pelican takes off, smoke pouring lightly from the left engine. The tentacle comes back and tries to wrap around the Dropship, but the Chief escapes its grip. The Pelican barely escapes from a massive explosion caused by the reactor going critical as High Charity is finally destroyed, and the Pelican makes its way to the new Halo ring.

Trivia

Glitches

Main article: Glitches

• During the level, the player will find dead Elites wearing Assault Armor. One of them is glitching by doing their death position in mid-air though; it looks like his foot seems to be stuck in Flood biomass. The corpse will fall if the player melees or uses explosives against it.

Easter Eggs

Main article: Easter Eggs

• The Tilt Skull can be found on this level.
• After obtaining Cortana, there is a skull on a ledge-like structure (it's purple and is kind of bulbous at the end) overhead after the player exits the hallway that leads to Cortana. To get it, one needs to get the Deployable Cover, deploy it on the floor directly in front of the edge of the roof, jump on the deployed cover and crouch jump onto the roof. One may also partner jump or grenade jump with a plasma grenade. Once on top of the roof, locate the skull towards the apex of the angled roof and get the skull. Please note that this skull has no affiliation with the "13 required skulls" list and, if carried for the rest of the level, will start Master Chief with a Spartan laser on the next level. This may only work with certain skull combination's and/or other factors in gameplay.

References

• This level is a reference to the Halo: Combat Evolved level, The Library, and the Halo 2 level, Sacred Icon, where the player has to retrieve Halo's activation Index and that it is a pure-Flood level. The only difference is that there are no Sentinels.
• The section of the level after saving Cortana is called 'Nor Hell A Fury...', referencing the poem by William Congreve 'The Mourning Bride'. The entire line is 'Heaven has no rage like love to hatred turned, Nor hell a fury like a woman scorned', possibly referencing Cortana, who, after months of torment, now has the ability to light the newly constructed Halo ring and destroy the Ark, as well as the Flood.
• Thematically, this level also has much in common with the levels Keyes and The Maw. It depicts the Chief venturing alone into a vessel to rescue a comrade or friend, from the Flood, most specifically for a data construct in their possession; and detonate the fusion reactor core. In this case the objective is the Index to fire Halo; in Keyes it was the Captain's neural implants to destroy The Pillar of Autumn.
• One of Cortana's lines, "There will be no more sadness. No more anger. No more envy," appears to reference Marathon's stages of Rampancy; Melancholia, Anger and Jealousy, respectively.
• The line "It's the coin's fault," is a reference to a factor that brought John-117 into the Spartan program. He identified the side of a 20th century quarter owned by Dr. Halsey that was about to the hit the ground before it did in Halo: The Fall of Reach.
• The Gravemind uses a line from Halo 2: "We exist together now. Two corpses in one grave." This line is referring to Cortana, and referred to the Prophet of Mercy in Halo 2. This line was said in the level "High Charity".
• The achievement for gaining over 15,000 points on this level, entitled Orpheus, is a reference to the ancient Greek mythology story in which the Greek hero Orpheus ventures into the depths of hell to retrieve the one he loves. This is easily compared to the Chief's mission: venture into hell, that is represented as High Charity, to rescue Cortana.
• The line "Just keep your head down... There's two of us in here, remember." is a reference to the Halo: Combat Evolved level The Pillar of Autumn. When the player's shield is completely depleted, Cortana would say the exact line, albeit with a more urgent tone.
• This is one of the many halo levels in the series that has the same name as a character.

Miscellaneous

• Due to Flood form action in the reactor's room, one of the four reactors explodes when the player first enters the room. This lead to the player's mission to only destroy three reactors instead of four.
• The Mausoleum of the Arbiter can be seen in the distance when standing near the crashed Pelican. This and the Prophets' Inner Sanctum are essentially the only recognizable features of High Charity in Halo 2 that can be seen in Halo 3. One can see in the Bungie feature "Flood Autopsy", that they had originally planned to have the Flood re-animate all Arbiter corpses in the room, creating an Arbiter army for the player to fight.
• The room where Cortana is located is a remake of the room from the level High Charity from Halo 2. This room is located before the final gravity lift, where Cortana says, "Apparently these are the Prophet Hierarch's private quarters, their inner sanctum". In the "inner sanctum" there are three doors, two located opposite one another, with a third, opposite a large view screen. In the level High Charity, the Chief enters through the third door, and exits through the door on his right; in the level Cortana from Halo 3, he enters through the door that was locked in Halo 2 (opposite the door that leads to the final gravity lift). The graphic design of the room and the rest of High Charity's interior has been remodeled in Halo 3. It resembles the corridors of the CCS-Truth and Reconciliation from Halo: Combat Evolved.
• There is an area with a dead ODST (not the crashed Pelican). It is unknown how he made it so far from the Pelican or if he was from the Frigate In Amber Clad before the Flood attacked High Charity. There is also a Flamethrower in this area which hints to a final stand since he's in a pipe area with one opening.
• On single-player campaign at the end of the level, a Banshee can be seen near the Pelican. While the player can reach it and destroy it, the player cannot enter it, and oddly, grenades will not stick to it.
• Much of High Charity is flooded with water; the reason for this is that it crash-landed in a large body of water near the Ark's Control Citadel. This can be seen by going out to the crashed Pelican and looking towards the Mausoleum and looking downwards.
• This level was originally split into two separate Campaign missions, both considerably shorter than the current level.
• According to a quote made by Bungie developer Jason Keith,, it is implied that the Flood Hive of High Charity and the Gravemind were one and the same during Halo 3, thus making this level seem like a boss fight, in a sense.
• Jiralhanae and Sangheili skulls can be found among the skeletal remains laying around the level.
• The entire Covenant cityscape once found on the lower levels of High Charity is believed to be completely engulfed in the ocean of unknown fluids seen throughout the level from a distance due to the fact that the cityscape's presence is completely absent.
• The room with the pillars and circular platform outside the window is actually the former High Charity Council Chamber.
• Numerous landmarks seen in High Charity in Halo 2 can be found throughout the level including, the Gravity Lift to the Mid Tower, one of the High Charity corridors, and the Council Chamber.
• This level has been infamous among the community for being overly difficult, repetitive, frustrating, and generally not very fun, along with Halo: Combat Evolved's The Library. The entire level is covered with Flood 'sludge', which is thought to be flesh of dead bodies. This means that the layout is sometimes disorienting, when it's not possible to tell directions, or even walls from floors. Enemies easily blend into the scenery, thus making the level very difficult. A few players have commented that the levels layout is simply too confusing for those playing it the first time - this is because of the enormous amount of enemies and maze-like pathways. Some fans have even claimed it is one of the worst Halo campaign levels ever made and a few have even labeled it as the 'worst video game level ever designed'. In contrast, other players enjoy the level for its challenge, and many praise Bungie for making this as realistic as possible.
• In the bone scattered cove before entering the reactor chamber, there is a small yellowish puddle of ooze with a striking resemblance to Fuligo septica also known as, "dog vomit slime mold".
