Mission Intel

From Halopedia, the Halo wiki

This article is about the audio logs found in Halo 5: Guardians. For other uses, see Audio log (disambiguation).

Mission Intel are objects found in the Halo 5: Guardians campaign. Replacing the Terminals from the previous games, Mission Intel are audio logs that fill the player in on backstories to various characters and events as well as an insight into their minds. Unlike the Terminals which were all identical in appearance, Mission Intel are depicted in different ways depending on the faction (i.e: Swords of Sanghelios/Jul 'Mdama's Covenant data discs and UNSC data pads). There are a total of 117 Mission Intel pieces that can be found throughout the campaign.[1]


Osiris contains seven pieces of Mission Intel.

Halsey Research Notes 1/4[edit]

Dr. Catherine Halsey's notes on signal observation - 00:17

  • "The signal is consistent with previous, I hesitate to call them, messages; that implies communication. This is more like, echolocation. A signal bouncing off Forerunner objects. Mapping! Searching for something. But what? What could she think to find?"

Halsey Research Notes 2/4[edit]

Dr. Catherine Halsey's notes on excavating the signal's focal point - 00:11

  • "We have penetrated the structure that was a focal point for the last signal. I have yet to gain access to anything informative. Jul's people are more concerned with ceremony than allowing me to do my work."

Halsey Research Notes 3/4[edit]

Dr. Catherine Halsey's notes on discovering a Forerunner glyph - 00:17

  • "Attained scans of new Forerunner glyphs. One is completely new. Running the other through the system revealed it contains a similar design to an ancient Sangheili symbol. This symbol referred to a demon who sleeps in the ground and must not wake. How this relates to the signal I am unsure."

Halsey Research Notes 4/4[edit]

Dr. Catherine Halsey's notes on erratic Forerunner signals - 00:15

  • "All of the readings I would expect from a Forerunner structure of this scale are erratic at best. I am beginning to wonder if the signal is in fact bouncing off these locations as I theorized or if she is trying to access them directly, and failing."

Jul 'Mdama's Log[edit]

Excerpt from Jul 'Mdama's operations log - 00:14

  • "The native defense system has been disabled, but Halsey was not able to bring the alert system down in time. Promethean forces will arrive within the hour. This human is more trouble than she is worth."

Unggoy Personal Log 005[edit]

Excerpt from the personal journal of Kibkib Yany, a Covenant Grunt - 00:16

  • "Jul 'Mdama, he say we go to Kamchatka and get big weapons, but this place is so cold. I hate it. But maybe, if weapon big enough, it can smash the Arbiter! I hope he goes squish when it happens. Or maybe pop, pop!"

Covenant Combat Orders 0283[edit]

Combat orders issued by Jul 'Mdama - 00:12

  • "Fall back to the perimeter of the holy site and hold the line! If you allow so much as a Crawler to get past you, I will remove your head myself!"

  3. To the right of the Hydra is the data pad.

Test Results: Asteroidea 472A[edit]

Results of compound Asteroidea 472A tests - 00:12

  • "Compound Asteroidea 472A: results observed. We almost have a candidate here. Sufficient morbidity. Adequate LD50. However, we must shorten its half-life."

Evelyn Collins: Meridian Day 1[edit]

Excerpt from the journal of Evelyn Collins - 00:20

  • "It's a hell of a return to your home...find it completely different. Ruined. I couldn't prepare myself for the cold feeling that struck my heart when that elevator rolled down through the planet's atmosphere. The world I knew...was gone."

Evelyn Collins: Meridian Day 5[edit]

Excerpt from the journal of Evelyn Collins - 00:28

  • "We started...cutting through the glass today. Making a road to a site they've picked out to set up a shanty town they call Meridian Station. I'm starting to wonder if I can do this. Most of the folks here are signed up for the profit. I'm the only one who’s here, trying to take something back! But there's just so much...I look out on that sea of glass and I...I wonder if it can ever really be done."

Evelyn Collins: Meridian Day 17[edit]

Excerpt from the journal of Evelyn Collins - 00:24

  • "Today I found myself working alongside another former colonist. Tough old broad named Lorie, Told her about what I'd been feeling. She laughed in my face! She told me, 'Sister, you gotta forget about what Meridian was, and think about what it could be.' I like that. So now, when I chip away the glass, I picture a new world we're making."

Shipment Received 2558-8-11[edit]

Manifest of goods received on 2558-8-11 from \[redacted\] - 00:13

  • "Got a new shipment in from Bozo: a Warthog, three Mongeese, and five Pelicans. Checked them, and they're all completely clear of identifiable markings. Bozo, contrary to his nickname, knows his business."

The History of Meridian 1/6[edit]

Free Frontier Education presents the History of Meridian - 00:19

  • "I've been putting together a retrospective on Meridian in these, her final days. Records indicate that 139 ships, carrying 70,003 souls arrived on this green ball in 2432. Since many of those settlers came from France, they named the first town Avignon, and established the colony of Meridian."

The History of Meridian 2/6[edit]

Free Frontier Education presents the History of Meridian - 00:19

  • "Early on, there was a big debate over the future of Meridian. Some wanted it to stay unspoiled and undeveloped. Others wanted to build it out. The debates between these Stewards and Prospectors came to an end when rich mineral deposits were found in the Mathon Mountain Range, causing a rush of new development as everyone tried to claim their piece."

Meridian Station[edit]

Eight pieces of Intel are available on Meridian Station.

Laser Operator's Personal Log[edit]

Meridian settler Priya Singh makes a mandated post-trauma entry - 00:09

  • "I found a body in the glass today. Shook me up. Doc Cale said I should talk about it, so here, I'm talking about it. Think I'm done now."

Meridian: Speculative Overview[edit]

A brief analysis of the extent of Meridian's glassing by William Khaleed - 00:22

  • "Meridian didn't get it too bad. They hit the human settlement hard, sure, and the plasma bombardment boiled some of the oceans off, but there was enough atmosphere to hold some steam in. Covies did a rush job, and the planet survived. Less than a third is lechatelierite. So we chip away at the worst parts like cutting away the rot off an apple. Quick job. Should be done inside of twenty years."

Excavation Team Personal Log[edit]

Excavator William Khaleed discusses the emotional toll of deglassing - 00:25

  • "The plasma they use to glass planets burns so hot most stuff just vaporizes. But sometimes there's a flicker in the beam and the temp drops just enough. That's how get you stuff that's still intact. And yeah, sometimes you get bodies. It's ugly, but I didn't get hung up about it. What gets me though is the dogs. Just excavated a homestead and there was a leash leading under the porch. So I'm taking the day off."

Deglass Team Personal Log[edit]

Deglasser Micah Durbec finds biological life beneath the glass - 00:19

  • "Cleared deep the other day. Cut through what used to be a forest. Dug through the glass and cracked right into a natural cave formation. Found actual plant life and pools of standing water with little white bugs hopping around in 'em. After working sterile glass for so long, seeing those bugs done me a world of good."

Deglass Team Incident Report[edit]

Deglasser Micah Durbec reports a subterranean structure of unusual metal - 00:20

  • "Running a top-level deglass south of the populated area, and we hit some kind of metal we couldn't cut through. Ran a pulse, and we got echoes of a subterranean structure or something. I don't know, I'm not on the anthro team. The thing is, there's loose soil beneath it, so whatever that metal is, it shrugged off a direct plasma bombardment. Damnedest thing."

Settler Personal Log, ID 4259[edit]

Meridian settler Priya Singh looks for meaning in glassing aberrations - 00:29

  • "The high winds the plasma kicks up? Scatters things for miles. Stuff can get thrown into the molten soil, and if it doesn't burn up, it- it sticks like a fly in amber. Or things get caught in bubbles of ash, like inside a snow globe. Sometimes things just happen. Like finding one single house, untouched in a glass field. Figure that's just to help us remember. Make us remember."

Settler Personal Log, ID 6421[edit]

Meridian settler Michelle Rivera imagines the future - 00:17

  • "Up on a station, everything's white and gray and bland. Some folk are afraid of any place the corners aren't round. Wouldn't dream of living down here, where the ground is ash and glass. Good riddance. Few years' time, kids who come up on Meridian are going to run this system. Bet your life."

Settler Personal Log, ID 0991[edit]

Meridian settler Joyce Leblanc defends Governor Sloan's rampancy onset - 00:19

  • "I don't get the guys who spend all day worrying about Governor Sloan. You can't deny he does a hell of job. Sure, he does that thing where he talks with two voices sometimes, but most folk do the same thing. Just aren't courteous enough to do it out loud. Doesn't bother me. I know he's got Meridian's best interests at heart."


There are seven pieces of Intel on Unconfirmed.

Message from Apogee Station 1/3[edit]

Message from miner Matt Riley regarding the anomaly at Apogee Station - 00:15

  • "Governor, just got a message from Thivyanathan. Losing his mind. Said he found something in the rock near Meridian Station. Unknown material, and too damn big to be man-made anyway. I need to check his readings, but I wanted to give you a heads-up."

Message from Apogee Station 2/3[edit]

Message from miner Matt Riley regarding the anomaly at Apogee Station - 00:13

  • "Governor, Thivyanathan talked me into letting him take a crew to see what was under the rock. He found, well, it looks like metal. Not slag. Nothing I know. I'll send you some sample readings shortly."

Message from Apogee Station 3/3[edit]

Message from miner Matt Riley regarding the anomaly at Apogee Station - 00:11

  • "Hey, Thivyanathan! Sloan's saying to force it open. He can't wait to see what's behind that door. He figures that Liang Dortmund might pay us a bonus if we find something good. Here's hoping for a finder's fee, yeah?"

The History of Meridian 3/6[edit]

Free Frontier Education presents The History of Meridian - 00:19

  • "Free Frontier Education presents The History of Meridian, Part Three. Despite the early success of the Prospector Party, the Stewards gained control of Meridian after a lengthy campaign known as the Free Patriot Movement. The Colonial Administration Authority eventually recognized the Stewards, ending years of strife."

The History of Meridian 4/6[edit]

Free Frontier Education presents The History of Meridian - 00:13

  • "Free Frontier Education presents The History of Meridian, Part Seven. Military production served as the colony's primary source of revenue, and the contract for the Scorpion MBT ensured Meridian's bright future."

Drill Operator's Personal Log 1/2[edit]

Drill Operator Philip Mistral comments on UNSC gel technology - 00:20

  • "Equipping a team to rehabilitate a glassed planet means accounting for its extreme conditions. Uniforms have to deal with extreme cold surface temps, as well as the heat generated by drills. Liang Dortmund set us up with some UNSC-developed tech, "gel-layer" they call it. Goes on under your clothes and keeps temperatures steady. This stuff is magic."

Drill Operator's Personal Log 2/2[edit]

Drill Operator Philip Mistral addresses Meridian's air quality - 00:20

  • "I should have listened to my brother when he said taking this job was a bad idea. The air is full of tiny glass particles, rip your lungs to shreds, you breathe enough of it. Between the masks and the air filters on every building, I haven't had a breath of unfiltered air in three years. Near the same as living on a space station."


There are six Intel pieces on Evacuation.

The History of Meridian 5/6[edit]

Free Frontier Education presents The History of Meridian - 00:15

  • "After five years of near-constant fighting, Insurrectionists lost control of Meridian to UNSC forces at the Siege of Aethia. Rank-and-file members of the Sundered Legion were offered amnesty by UNSC officials, although their leaders would go on to stand trial in UEG courts."

Offworld Message 1/3[edit]

Meridian settler Brandon Pemberson's message about the evacuation - 00:13

  • "Matilda, I just thought you should know we're being evacuated. Now, don't panic, I'm sure it's nothing. Sloan just wants us to get clear of some potential trouble, and we'll be safer off-world. I’ll call again when I’m clear.”

Offworld Message 2/3[edit]

Meridian settler Brandon Pemberson's update about the evacuation - 00:14

  • "Matilda, I just watched the last Mule take off. There's no more ships left. Sloan's telling us to move to the space elevator, so they're moving us to Warthogs. There's a lot of fighting going on out there, though. It doesn't seem safe."

Offworld Message 3/3[edit]

Meridian settler Brandon Pemberson's final message to his loved ones - 00:14

  • "Matilda, I made it to the elevator, but now I'm stuck at the base. There's a huge line. I guess it wasn't made to carry so many people at once. I'm sure it'll be my turn soon, Matilda. I'll send you another message when I'm in orbit."

Public Update: Glass[edit]

A basic overview of the composition of a glassed planet - 00:15

  • "The so-called glass is a mineral called Lechatelierite. It is a result of the Covenant lances striking the surface of the planet with plasma, converting the topsoil to glass. Any attempt to make a glassed planet habitable would mean cutting the surface down to below the topsoil

The History of Meridian 6/6[edit]

Free Frontier Education presents The History of Meridian - 00:20

  • "Almost immediately after Meridian was recaptured by the UEG, the Covenant arrived. Captain Edmund Persie of the UNSC Sevenfold Gates fought to the last, but was forced to order what few ships remained to fall back to the edge of the Hestia system. Within five hours of Captain Persie's retreat, Meridian was glassed, and all life there was eradicated."


A total of seven Intel pieces are on the level Reunion.

Unggoy Personal Log 083 1/2[edit]

Jeem Ribfi, a Covenant Grunt, has a religious epiphany.- 00:09

  1. Play through the level all the way until you get close to the first area with enemies.
  2. Turn left into a cave that eventually leads to a ledge.
  3. Towards the end of this ledge, you will find the data disc near Jeem Ribfi's dead body and a few Covenant boxes with a Needler sitting on top of them.

Unggoy Personal Log 083 2/2[edit]

Jeem Ribfi, a Covenant Grunt, has another religious epiphany.- 00:09

  • "Uh! I was wrong! The Demon has come! This is our punishment! They looked in my head and saw that I doubted! Ohh, I never should have doubted!"


  1. Travel to the first area with enemies. Here, Frederic-104 will say "There's the rest of the Covenant." if you already encountered Jeem Ribfi's corpse before; otherwise, he will say "Sounds like an Elite. What the hell are the Covenant doing here?".
  2. Go to the right as if wanting to obtain the Grunt Birthday Party skull.
  3. Turn left to a small ledge that has a Covenant data disc on it.

UNSC Marine Status Update[edit]

  • Note: This piece of Mission Intel has a typo and is actually spelled "USNC Marine Status Update" in the menu.

A fragment of a log update from a UNSC Marine - 00:10

  • "Separated from the rest of my squad. We were pulled in from patrol around Oban and landed...wherever this is. Bunch of Covies already here, too. That's no good."


  1. After clearing the first group of Covenant, go to the rock cliffs on the right.
  2. Turn around, jump, and climb into a dimly-lit alcove.
  3. The data pad is located inside, next to a dead UNSC Marine whose body is partially submerged into the floor, a Rocket Launcher, and a Railgun.

Forerunner Record: Search 1/5[edit]

Excerpt of a recording by an undesignated Forerunner Builder - 00:16

  • "With Bastion beyond my grasp, I turned to the possibility of the Domain. However, there is corruption. The source, untraceable. Investigations, but no returns. Time grows short."


  1. Go to the Forerunner temple that acts as the second activation site for the Gateway.
  2. Walk into an underground alcove in the center. At the end of it is the Forerunner console. When entering the alcove, though, watch out for the Shade Turrets guarding the temple above, especially on higher difficulties.

Forerunner Record: Search 2/5[edit]

Excerpt of a recording by an undesignated Forerunner Builder - 00:22

  • "Acquisition of a durance proved difficult in these final days. An ancilla has agreed to aid my efforts, yet there is concern if he will carry through. However, if Bastion has indeed achieved the impossible, I must find a way of reaching them. If that path be through death and Domain, so be it."


  1. Once you clear the first group of Prometheans, head through the canyon.
  2. Take the lefthand path. Towards the end of it is a Forerunner console sitting next to a gap. Watch out for Armiger Officers with Splinter Turrets, though.

Forerunner Record: Search 3/5[edit]

Excerpt of a recording by an undesignated Forerunner Builder - 00:11

  • "Bastion is absent. Not destroyed; simply missing. No other facility is near enough. A new course of action is required."


  1. After defeating the Warden Eternal and his Promethean forces, cross the light bridge to the final activation building.
  2. The Forerunner console is found sitting behind a wall on the platform in front of the light bridge.

Forerunner Record: Search 4/5[edit]

Excerpt of a recording by an undesignated Forerunner Builder - 00:13

  • "Bastion's location is confirmed. How, though? After dispersal of the Halos, an impossible act of reconciliation would be required. It may still be possible."


  1. Upon starting the second part of the mission, go forward until you see a breakable wall to your left.
  2. Destroy the wall and go to the right to enter a spiral-like walkway.
  3. The Forerunner console sits at the bottom of the walkable area, with a waterfall to the right.

Patrol Log - Scout 'Ghattam[edit]

Scout Jaruth 'Ghattam goads hidden Covenant forces into attacking - 00:14

  • "Claim allegiance to the Arbiter, but a traitor's working with the Covenant! Why do you skulk in the shadows? Come draw your blades! You live without honor! Must you die the same way? I will kill you all myself!"

Patrol Log - Scout 'Thrun[edit]

Scout Thet 'Thrun revels in the defeat of Jul 'Mdama - 00:10

Kit Pitlimp's Adventure Log 1/4[edit]

The inquisitive Kit Pitlimp searches for Forerunner secrets - 00:18

  • "I am Kit Pitlimp the explorer. The Covenant's future depends on ancient Forerunner secrets. That's what Jul 'Mdama said, so I will look for them. I know there are some old places around here. I will investigate at night so no Arbiter forces can see me."

Patrol Log - Scout 'Makesh[edit]

Sword of Sanghelios Jacul 'Arach urges his Covenant-loyal brother to join the Arbiter - 00:16

Sword of Sanghelios Jacul 'Arach urges his Covenant-loyal brother to join the Arbiter - 00:21

  • "Kitun 'Arach, my brother. I remember our first hunt together, when we brought our prey home, it was a moment of greatness, of hope. The Covenant brings only shame to the Sangheili, but it will soon fall. I wish to hunt with you at my side again, brother. It is not too late."

Sangheili Personal Log 139[edit]

Covenant Elite Thev 'Mura threatens the Arbiter - 00:14

An audio log by Scouts Rhee and Vatha 'Hakkat captures a Covenant ambush - 00:22

  • "Another day of endless meetings. Our talents are wasted here."


Eight pieces can be found on Alliance.

Camp Quartermaster Personal Log[edit]

Sword of Sanghelios Lhero 'Merok explores the symbolism of his campsite - 00:27

  • "We camp below the titans of old, the stone warriors meant to guard Sunaion against us, I suppose. Or are we retaking Sunaion from the occupying Covenant, with the titans at our backs. And when the great Guardian awakes, will it save us, or forsake us? My head swims. I long for problems that can be solved with a plasma grenade."

Sangheili Medic's Personal Log[edit]

Sangheili Medic Cham 'Lokeema discusses his social status - 00:34

  • "To spill blood outside of battle is a great dishonor. Words burned into all Sangheili since they were young, and to me. And for a time, I believed. I watched my brothers die around me and never dared give aid. 'Stitching a wound closed brings dishonor, setting a broken bone brings dishonor.' Words of the ignorant who never saw undetonated Needler rounds pulsing beneath a brother's skin. If shame is the price of compassion, so be it."

Sangheili Linguistics Report[edit]

Kholat 'Khebrem, a Sangheili linguist, studies ancient glyphs - 00:36

  • "Anthropological linguistics log, Kholat 'Khebrem speaking. Our history is lost in a haze of lies and myth. As the Covenant ends, I wish to relearn what we've lost. But the eroded and half-ruined glyphs in this place are maddening. Fragments of words dance before me. Here, 'prophecy', and here 'reunite' or 'restore'. Then a warning, something about 'responsibility' and 'a great drowning'. I could study here for years."

Sangheili Personal Log 673[edit]

Sword of Sanghelios Thon 'Kemtra admires the leadership of the Arbiter - 00:36

  • "We set camp within sight of Sunaion. Audacious, but brilliant. We Swords of Sanghelios are united under no less a warrior than the Arbiter himself. He who exposed the countless lies of the San'Shyuum, and drove back the Covenant. The Arbiter shapes our future with deference to our past. 'Let us never forget those who have journeyed into the howling dark and did not return,' he once said. Have you ever heard such wisdom?"

Sangheili Personal Log 383[edit]

The personal log of Rhu 'Vrath, a Covenant-loyal assassin - 00:33

  • "When I joined the Swords of Sanghelios, I remained loyal to Jul 'Mdama. Today, I had my chance to kill the heretic, the false Arbiter. He was readying his armor. My hand fell to my weapon, then I saw the mark branded on his chest. He bears the mark, yet at that moment, I felt shame. His eyes caught mine and I looked away. It is strange. Perhaps there is more to him than I thought."

Honorguard Personal Log 1/2[edit]

Sword of Sanghelios Vari 'Damat discusses sharing camp with the Arbiter - 00:29

  • "I'm stationed so close to the Arbiter, and gods, I have never felt so nervous. I set about polishing my armor straight away, but then thought the Arbiter might frown on such vanity. In battle, should I fly my Banshee to the front and show my skill, or would he see that as recklessness? I'm petrified. I would recuse myself from battle, but that would definitely disappoint him, would it not?"

Dr. Halsey: Status[edit]

A message by Dr. Catherine Halsey to the Arbiter, Thel 'Vadam - 00:28

  • "Catherine Halsey, status update. I'm playing along with your protocol here, Thel. If the Four's bring me an active Constructor, I can interface with the Guardian. It will receive Cortana's signal the moment it activates and initiates slipspace, but I think I can make sure it leaves the sea before it jumps. I'll get it in the skies over Sunaion, like you asked. In return, send me some assistants with brains in their heads. And loosen this damn security! I'm not going anywhere."
