Looking for Installation 05?

"A Covenant army stands between you and Regret. Get to work."

Delta Halo is the eighth campaign level of Halo 2. After dropping onto Halo in an HEV, John-117 fought his way through Covenant forces to reach the temple where the Prophet of Regret resides. This is the only Halo 2 level where you will be aided by ODSTs and is also the first level you fight Honor Guard Elites.


{Cutscene} {Anniversary}

A Slipspace rupture appears in space. Regret's Carrier comes out, followed by some debris from New Mombasa and the UNSC In Amber Clad.

Cut to interior of In Amber Clad:

  • Ship Operations Officer: "Both engine cores have spun to zero. We're drifting."
  • Weapons Officer: "Archer pods are cold. I'll need to re-key the system."
  • Commander Miranda Keyes: "Do it, and find out where we are."

Pan over to a room lined with HEVs:

  • Commander Miranda Keyes (COM): "Sorry for the quick jump, Sergeant. You in one piece?"

Johnson is inside a HEV pod, smoking a smashed cigar.

Shot of John-117 in another pod.

  • Communications Officer: "Ma'am, there's an object. Coming into view now."
  • Commander Miranda Keyes: (stares in amazement) "Cortana, what exactly am I looking at?"
H2A Cutscene IACApproachingI05

In Amber Clad over Installation 05.

The In Amber Clad heads toward Delta Halo.

  • Sergeant Major Avery Junior Johnson: (chokes) "Say what?!"
  • Commander Miranda Keyes: "So this is what my father found... " (gazes at Halo) "I thought Halo was some sort of superweapon."
  • Cortana: "It is. If activated, this ring will cause destruction on a galactic scale."

In the pod, John-117 looks at Halo on his viewscreen. The words "CLASSIFIED" and a notice from the Office of Naval Intelligence appear over the image.

  • Commander Miranda Keyes: "I want all the information you've got on the first Halo. Schematics, topography, whatever. I don't care if I have the clearance or not."
  • Cortana: "Yes, ma'am."
  • Commander Miranda Keyes: "Where's our target?"
  • Communications Officer: "The enemy ship has stopped above the ring, ma'am. We're going to pass right over it."
  • Commander Miranda Keyes: "Perfect. Given what we know about this ring, it's even more important that we capture the Prophet of Regret. Find out why he came to Earth, why he came here. Chief, take First Platoon. Hard drop, secure a landing zone. Sergeant, load up two flights of Pelicans and follow them in."
  • Sergeant Major Avery Junior Johnson: "Aye aye, ma'am."

Johnson exits his pod.

  • Commander Miranda Keyes: "Until I can move and fight I'm going to keep a low profile. Once you leave the ship, you're on your own."

Johnson knocks twice on the hatch of John's pod as he is walking by, John-117 pounds back in acknowledgment.

  • Crewman 2: "Over the target in five..."
  • Cortana: "Hang on to your helmet!"

The pods drop, and the platoon hell-jumps onto Halo.

  • Cortana: (as the parachute deploys) "Mind the bump."

On Halo, an Unggoy and a Kig-Yar notice the pods flaming and streaking down towards them. The Kig-Yar Minor snarls in alarm. He flicks his wrist, and his energy shield snaps on. The Unggoy boards on the Shade and shoots at the pods, and soon another Shade starts firing. The pods land, John-117 breaks the cover open on his pod, scanning the area with an SMG.

  • Cortana: "Could we possibly make any more noise?!"

John-117 takes up a Rocket Launcher out of his pod and hefts it.

  • Cortana: "I guess so."



They come under fire of the Shades.

  • ODST (Private First Class Chips Dubbo): "Sir, we gotta neutralize those turrets!"
  • ODST Sergeant (Gunnery Sergeant Marcus Stacker): "Clear this landing zone! The Pelicans are right behind us!"

When John takes out all Covenant in the area:

  • Cortana (COM): "Artillery disabled, Sergeant. Landing zone secure... for the moment."
  • Sergeant Major Avery Junior Johnson: "I hear ya. Starting our approach - hang tight."
  • Cortana: "Easier said than done. Inbound Phantoms, Chief."

A Phantom drops off troops. John eliminates them

  • Cortana: "Another Phantom, on approach."
H2A DeltaHalo4

Two ODSTs in battle.

A second Phantom drops off troops. John-117 eliminates them as well.

A third Phantom drops off a squad of three Spec Ops Sangheili and a Stealth Sangheili on Legendary.

  • Cortana: "Hold here until the Pelican arrives, Chief."

If John stays and waits for the Warthog

  • ODST or Cortana: "Here comes our ride!"

A Pelican arrives, dropping off a Warthog and two Marines, if the ODSTs have been killed.

If John-117 proceeds up the path without waiting for the Pelican to arrive

  • Cortana: "Let's wait here until our Warthog arrives...unless you'd prefer to walk."
  • Sergeant Major Avery Junior Johnson: "I got a good view comin' in. There's a big building in the middle of this island's lake."
  • Cortana: "I saw it too. It looks like a temple. If I were a megalomaniac--and I'm not--that's where I'd be."

The Pelican drops the Warthog.

  • ODST Sergeant: "Saddle up! We're movin' out!"
  • Dubbo: "Whoa...it's like a postcard! 'Dear Sarge: kicking ass in outer space, wish you were here.'"
  • Sergeant Major Avery Junior Johnson (COM): "I heard that...jackass!"

Later, John-117 comes across a bridge held by the Covenant.

  • Cortana: "The Covenant have control of the bridge ahead. They're going to try to bottle us up on this side of the gorge. The controls to extend the bridge should be in this structure."
  • ODST or Cortana: "Watch out, Chief! Wraiths on the far side!"

After extending the bridge:

  • ODST or Cortana: "Good, the bridge is down. Now about those Wraiths..."
  • Sergeant Major Avery Junior Johnson (COM): "Roger that. Armor's on the way."

If John-117 stares at Regret's hologram, then walks up to the ODST

  • ODST: "Isn't that our target? What's he doing? Giving a speech?"
  • Cortana: "A sermon, actually. I've been listening to it since we landed. So far, some standard Covenant literature, but I'll translate if he says anything interesting."

If John keeps staring at the hologram

  • Cortana: "Regret's giving a speech. A sermon, to be exact. So far it's the standard Covenant liturgy, but I'll translate if he says anything interesting."

Another Pelican approaches, carrying a Scorpion Tank.

If you choose to go on foot, Warthog, or Ghost.

  • Cortana: "You don't want the Tank? Okay, we'll leave it for the others."

John-117 passes through a multitude of Forerunner ruins.

You Break It, You Buy It[]

  • Cortana: "Careful. We're coming up to another structure."

During the attack on the structure:

  • Marine ODST: "We got a Pelican coming in! Let's clear a landing zone!"


  • Marine ODST: "Gotta Pelican coming in! Let's clear a LZ!"


  • Cortana: "Pelican inbound! Let's clear a landing zone!"

After the Pelican drops some weapons, more Covenant arrive.

  • ODST or Cortana: "They're all pouring out of the middle! Let's get in there."

Once the outside is clear.

  • Cortana: "The Covenant are holed up in the middle of this structure. We need to clear them out."

As you progress into the building, you come across a hologram of the Prophet of Regret

  • Prophet of Regret (Hologram): "In a gesture of peace and reconciliation, the Prophets promised to find the means of the Forerunners' transcendence, and to share this knowledge with the Elites. The Elites promised to defend the Prophets as they searched. A simple arrangement, that has become our binding Covenant!"
  • Cortana: "Transcendence, huh? More like mass suicide."

Off The Rock, Through The Bush, Nothing But Jackal[]

H2A DeltaHalo3

The waterfall part of the level.

Later, you find more Covenant near a waterfall flowing into a creek

  • Cortana: "You always bring me to such nice places."

After that, you reach a massive temple

  • Cortana: "Good, still no word about In Amber Clad on the Covenant battlenet. It's odd, the Covenant knew we made landfall, but they don't seem to consider us a very serious threat. Boy, are they in for a big surprise."

As you enter the temple, you find two Honor Guards standing next to another Regret hologram

  • Cortana: "Watch yourself! Honor Guards!"

John-117 kills the Honor Guards. Fades to white.

Level ends.


Originally, Bungie had planned for the level to begin while John-117 was still in the Orbital Drop Pod. Two Pelicans would fly by a window in the pod, which the player would have to save them from the turrets seen in the opening cut scene. However, this feature was cut due to bugs and a time shortage.[1]

Main article: Glitches
  • If you jump what looks like a ramp onto the building where you extend a bridge while the bridge is still going up, you will jump a lot higher.
  • Because Delta Halo is the first part of a two-part level, your weapons will carry over to Regret, unless one of your weapons a pistol. If you finish Delta Halo with a pistol you will start Regret with a Beam Rifle and an SMG.
  • Using the Sputnik skull, it is possible to jump into Regret and find The Gate, which is a switch located where the first Gondola would arrive. Upon opening it you will hear the noise the Gondola makes when you start it up. It has been highly controversial between Halo fans because no one knows its purpose although it is most likely to be a place holder for the Gondola itself.
  • At the beginning of the level, when you clear the Covenant from the first structure, move onto the bridge area, and get the Scorpion. If you do this, the game will act as if you did not go get the Scorpion, and will spawn a Warthog. Cortana will also say "Let's wait for the Warthog, unless you'd rather walk" on your way back through with the tank.
  • When looking directly at the holographic projections of Regret, press the "melee button" and John will charge towards the projection as if you were actually about to melee an enemy unit. This is because, to save time, an alternate model of Regret with no collision model is used for holograms. This also occurs on the holograms viewing the Heretic Leader at the beginning of the level The Oracle, and The Prophet of Truth on the Halo 3 level The Covenant.
  • At the starting of the level when you hold the Temple with the Helljumpers where the Kig-Yar and the Unggoy were in the cinematic, climb up the hill, walk around until it says Loading...done. After that, go somewhere low that you can get to the ground without dying. There will be no enemies for the whole level, but you'll also be unable to get to the next level because a door will be locked. Also, all holograms of the High Prophet of Regret will just be of his Gravity Throne, with no Prophet sitting in it. In addition, at the set of buildings before the last checkpoint, you can drive a Ghost up to the area of gondolas in the next level. There will be no enemies. However, this area is inaccessible. You will fall and die instantly.
  • When you reach the temple where you must clear a Landing Zone for the Pelican and its drop pods, after you eliminate all enemies that exit the temple, about half the time all surviving ODSTs (only a maximum of 3) will suddenly vanish. Rarely, only one or two will vanish. The Marine reinforcement(s) will never disappear, only the Helljumpers.
  • After Cortana says "The controls to extend the bridge should be in this structure," drive your Warthog onto where the bridge extends. When the Wraith comes out and shoots at you go forward very slightly so that the Wraith shot will hit the back of the 'Hog. You will go flying over the gorge and land on the other side. However, even on Easy, you will die upon impact of landing. For a better view, after the Wraith hits the back of your Warthog, get out of it. You'll die the moment you get out, but you'll get a much better view, and sometimes, you'll fly over the next structure. If you are in a Ghost, and haven't yet extended the bridge, if you go where the bridge would be, and the wraith's mortar hits you, its possible that you will be flung over the gorge, and hopefully stay alive. You can continue the level if this happens.
  • It is possible to enter the next level (Regret) without activating the cut scene. The Sputnik Skull is not required for this glitch, though it does help. First, go through the level on any difficulty until you reach the part where you are on the bridge with the Weapon Pods that the In Amber Clad dropped for you. Instead of going into the tower, grenade jump on the side of the entrance to the platform above. Kill all the Jackal Snipers. Then, find your way around and jump down. You will be on the other side. There will be Covenant soldiers with most of the Grunts sleeping. They will act as if you were not there unless you bump into them. Continue to where the gondola is and you will see what appears to be a Zanzibar gate switch hovering off the coast of your platform.
  • The first hologram of Regret in the courtyard like area in the structure that you come to has a part where you can stand on it as if it was a solid object.
  • This is one of the few levels in the game where the Permanent Invisibility glitch can be preformed.
  • If you extend the bridge at the area where you get the scorpion tank, but instead get in a ghost, it is possible to get into Delta Halo's mountain range. Take out the wraith, as well as the enemy ghosts which come out of the tunnel. Go to the tunnel, but don't go inside. Instead, turn around. There should be a regular steep rock wall, with the extendable bridge to your left. Boost towards the wall. Instead of hitting it, you will begin to ride up the wall. Eventually, you will get to the top and you will be able to explore the mountain ranges. There are also giant see-through holes in the terrain, which you can easily fall into and die.

Easter Eggs[]

Main article: Easter Eggs
  • The Envy Skull is found on this level.
  • There are three hidden Rocket Launchers in this level; one on the top of the first structure, which to get to you have to go to the balcony, look to the right, walk on the side of the structure, then crouch jump on top. The second is at the part where it says "you break it, you buy it. Go to where the swirling ramp is and try to park your Scorpion in a way that you can reach the ledge with the trees. In the trees, there will be a dead ODST with a rocket launcher. The third one is at the structure where the first Pelican drops in reinforcements. You have to go to the corner that is through the tunnel of where the Envy skull is. You have to grenade jump up that corner, walk across the "balcony," and look to the left after the giant piece of broken wall. There is a Marine corpse with a Rocket Launcher.
  • The Unggoy with Toys Easter Egg can be found on this level.
  • There is a Tri-Gate outside the level.
  • If you managed to reach the bridges at the last structure of the level, you can walk up to any of the Covenant forces in that area and none of them will attack you. Instead they will simply stare at you, make a random comment and run off. The Sputnik Skull may be required to achieve this task.
  • It is possible to go outside the boundaries of the map near the very beginning. You can explore the entire level up to the part when you get on the gondola, from outside the valley the level takes place in.
  • At the Checkpoint "Off The Rock, Through The Bush, Nothing But jackal," there is a hidden energy sword if you follow the stream from the waterfall.
  • Around the area of where the Envy skull is found, in the room where there's a giant block covering the doorway, there is a way of getting in the room and finding two energy swords and two dead Grunts. Just go as if you were going to get the Envy skull, and drop down the right side of the building. In the dark room, there should be two dead Grunts, and two energy swords. And you should also be able to see the block covering up the initial doorway. The block can be removed through the use of grenades.
  • There is a total of 13 ODSTs in the whole level. Three will already be alive. There are four dead ODSTs as soon as you land, but the fifth dead ODST is on top of the middle structure; there is also a rocket launcher next to him. The 6th ODST is on a ledge by the control room to lower the bridge with wraiths on the far side; there is also a sniper next to his body with eight bullets. The 7th ODST is sort of hard to find, but there is a rocket launcher next to his body. The 8th ODST is where the second Pelican drops off ammo pods with a rocket launcher. The 9th ODST is in a cave near the waterfall with two pistols. The last ODST is at the very end of the level on a ledge overlooking the structure you have to go in. The 11th, 12, and 13th are the only live ones as soon as you land.
  • The Envy Skull is found on this level. This is similar to the Hidden Sniper Rifle, which can also be found on Delta Halo. Near the end of the level, after the area with the waterfall and snipers, you will go through a tunnel and come out onto an open ledge. There will be several buildings in the distance and if you still have a Sniper Rifle or Beam Rifle, you can pick off several Unggoy, Kig-Yar, and Sangheili. Below the ledge you are standing on is the main ledge which has weapon drop pods, however if you turn right and go along the wall, you'll reach a point where you can jump up and walk along above the main ledge. This will deposit you on a hidden ledge covered in thick vegetation. On the ledge is a dead ODST and a Sniper Rifle.
  • The Floating Switch can be found in this level.


  • In the opening cutscene, behind Miranda Keyes in the bridge of the In Amber Clad, screens can be seen with ODPs on them, this is also seen on Elongation, The Armory, and in the Cairo Station level.
  • Also in the opening cutscene, when the HEVs come down, you can see a crude image of Africa on Delta Halo when they show a downward facing view of all of the Marines and ODSTs coming down on impact.


  • The Delta Halo Vacation can be done on this level.
  • In the opening cutscene, a drop pod can be seen in the background behind the turret. This is the same drop pod that can be seen during the gameplay, so this is most likely a continuity error.
  • The opening cut scene plays in two parts. If you skip the first part of the cut scene then the music which normally plays as the SOEIV's land (part of Delta Halo Suite) will not play and the cut scene will finish without music. This is likely because normally the music is triggered in the first part of the cut scene and carries over into the second.
  • In the first cutscene you can see chunks of the skyscrapers from New Mombasa which were pulled into Slipspace. They aren't very detailed, though.
  • There is a rocket launcher located on the top of the Forerunner structure with an ODST besides it. The rocket has full ammunition.
  • The birds flying around (at the beginning where the Wraiths are) can be killed with a Beam Rifle, Battle Rifle, Covenant Carbine, or the Scorpion's machine gun; and they will explode into a blur of red blood and die. There are more of these birds in the level Regret and they can also be seen on the Halo 3 level Guardian.
  • This is the only level by default in Halo 2 that you start with a Rocket Launcher.
  • You can see the Sentinel Wall in the distance, implying that the area is pretty close to the Library.
  • This is the last level where John-117 will have the opportunity to drive a vehicle.
  • If you kill the first three Honor Guards inside the building, the beginning cut-scene for Regret will begin. If any are killed outside it, a fourth one will be on the second level, to the right.
  • It is possible that Sergeant Stacker and Sergeant Banks appear as both an ODST and a Marine in this level.
  • For the first time in Halo 2, you can see two Kig-Yar using Plasma Rifles against you.
  • When you have cleared the landing zone and the Pelican has arrived with a Warthog and two Marines, you can hear a song that doesn't appear on the soundtrack.
  • While looking through the caves in the area with the waterfall and creeks, you will see the body of a lone ODST that was armed only with two pistols which may seem somewhat strange since there isn't any evidence of HEVs other than the ones that landed alongside you in the beginning of the level.
  • When Regret's hologram is encountered throughout the level, his chanting sounds vaguely similar to the Halo theme song.
  • If you are playing on Legendary, at the beginning of the level, a third Phantom will drop off a squad of four Sangheili. All have active camo, and one is a dark brown Stealth Sangheili.
  • When you fight the Honor Guards, go up to the rubble pile and crawl through it, you will fall alongside a carbine and plasma grenades.
  • "Helljumpers" is actually another name for ODST, Orbital Drop Shock Troopers. They are elite special forces trained to the art of guerrilla tactics and unconventional warfare. They mainly specialize in clandestine and internationally illegal roles involving reconnaissance as well as assassination.
